Antalya Alanya highway: where it ends, when it opens and what it changes for Alanya

The Antalya Alanya highway is a toll motorway under construction that ends at the D-400 in Telatiye, east of Konaklı, opens by October 2028 under its contract, and changes the trip to Alanya less than its 36-minute headline suggests. The highway's 84 km main line runs from Serik to a point north of Konaklı, where cars will most likely drive at 140 km/h, the limit Turkey's General Directorate of Highways sets for build-operate-transfer motorways, but the D-400 coastal road still carries the traffic at both ends. The lenders' traffic study therefore models a saving of about 30 minutes for long-distance drivers, which brings an Antalya Airport transfer to roughly 1.5 to 2 hours rather than to 36 minutes. Tolls start from a December 2023 bid of EUR 0.0598 per km before VAT (value added tax), about EUR 5.29 between the Serik and Alanya toll stations, and the state guarantees the operator revenue for 100,000 car-equivalent vehicles a day, four times the traffic forecast for 2028. In the Alanya district, the motorway's three junctions, its quarries, a construction camp and the predicted noise exceedances concentrate in the west, from Çakallar to Telatiye, while Oba, Kestel and Mahmutlar gain through the Eastern Ring Road from Hasbahçe, and Kargıcak still waits for the ring road's last 3.2 km. The project's own impact assessment expects property values to rise near junctions but gives no figure, and no published study measures a price effect. Owners of the 1,080 affected parcels in Alanya face a negotiation round planned for the end of 2026, with 15 days to answer the state's purchase offer before the case moves to court.

What is the Antalya Alanya highway?

The Antalya Alanya highway is a toll motorway under construction between Serik and the western edge of Alanya, financed and built by a private company under a build-operate-transfer contract with KGM (Karayolları Genel Müdürlüğü, Turkey's General Directorate of Highways). Its main line runs 84 km with three lanes in each direction. Seven junctions connect the main line to the existing road network through two-lane link roads. The contract holder, Antalya Alanya Otoyolu İnşaat Yatırım ve İşletme A.Ş., belongs to the Limak group.

Build-operate-transfer, yap-işlet-devret (YİD) in Turkish, decides who pays for the road and who earns from it. The company builds the motorway, collects the tolls for a fixed period and then hands the road to KGM. The concession for the Antalya Alanya highway lasts 15 years: 3 years of construction followed by 12 years of operation. Both the project's Environmental and Social Impact Assessment (ESIA), ÇSED in Turkish, and the project page of the Asian Infrastructure Investment Bank (AIIB), one of the lenders, give that split. On the contract timetable, the motorway therefore passes to the state around 2040.

The traffic study attached to the ESIA puts total investment at about EUR 2.3 billion (2024 estimate), and the project company signed EUR 1.7 billion of loans in October 2025. Five tunnels with a combined length of 4,365 m and 16 viaducts with a combined length of 5,966 m carry the main line. Sources that still quote eight tunnels and 19 viaducts are using the December 2023 tender announcement, made before the design was revised. All five tunnels lie between Km 54 and Km 89, in the Serik and Manavgat districts. The Alanya section has no tunnel at all, and crosses Akdam, Türkler and Emişbeleni on two viaducts instead.

Which highway numbers measure what?

Ten numbers circulate about the Antalya Alanya highway, and most of the contradictions between sources come from setting numbers side by side that measure different things. Each figure has a defined scope and a named source.

The two time figures answer different questions. The 36 minutes is how long the main line takes at 140 km/h. The 30 minutes is how much shorter the modelled trip becomes once the D-400 legs at both ends are counted. A buyer comparing an agency's "36 minutes to Antalya" with a transfer company's quote is comparing a motorway segment with a whole journey.

Where exactly does the Antalya Alanya highway end?

The Antalya Alanya highway's main line ends at Km 136, north of Konaklı, and a 5.7 km two-lane link road then turns south and joins the D-400 in Telatiye, east of Konaklı. Telatiye is a neighbourhood of the Alanya district, between Konaklı and Alanya city centre. The junction there, Alanya Batı (Alanya West), lies inside the area covered by the town's zoning plan, and the ESIA schedules construction works on the D-400 itself at that point.

KGM describes the motorway as ending at the Alanya West junction north of Konaklı, which is true of the main line. A driver comes back down to the D-400, the coastal state road, at Telatiye, about 5 km further on and still west of the city. Neither the ESIA nor the project's Resettlement Action Plan (Yeniden Yerleşim Eylem Planı) mentions any connection to an Alanya ring road. The link road itself was added at KGM's request after the 2018 environmental impact assessment.

The gap was raised at the ESIA public meeting in Konaklı in August 2025, where a resident complained that the motorway offers no entry into Alanya after Konaklı and asked for the road to continue. A driver bound for Oba, Kestel or Mahmutlar starts the drive through or around Alanya at Telatiye, on the D-400, whatever the motorway has saved before that point.

Which junctions does the highway have, and where does each one lead?

The Antalya Alanya highway has seven junctions, and each one reaches the existing roads through its own link road with a toll station on it. The ESIA lists the junction positions, the roads each link joins and the link lengths.

Three junctions serve the Alanya district: Alarahan, Konaklı and Alanya Batı. Alarahan sits near Çakallar and reaches the coast along the Okurcalar-Alara road. Konaklı junction was moved north during design, near Km 132+500, to avoid buildings that appeared after KGM approved the preliminary design in October 2024. The longest link is at the Antalya end: drivers from Antalya leave the D-400 at the Serik trumpet and drive 10.7 km inland before the main line begins at Km 52.

The gap between Alarahan (Km 117.6) and Konaklı (Km 133.4) is about 16 km with no exit. That stretch runs above İncekum, Avsallar and Türkler, so Avsallar, the largest of the three by population, has no junction of its own. An Avsallar resident heading to Antalya Airport would join at Alarahan or at Konaklı, depending on where in Avsallar the apartment stands.

Does the highway connect to Antalya Airport or reach Gazipaşa?

No. The Antalya Alanya highway connects to neither airport: traffic from Antalya Airport reaches the motorway along the D-400, and the motorway stops west of Alanya, while Gazipaşa lies a further 44 km east of Alanya. The 44 km follows from KGM's official distance table, which places Alanya 138 km and Gazipaşa 182 km from Antalya by road.

The airport side improves without a direct link. The ESIA includes the last 10 km of the D-400 before Serik junction, between the end of Antalya's Northern Ring Road and the Serik trumpet, in the project. That stretch is being rebuilt from two to three lanes in each direction, and its at-grade junctions at Çardaklı and Kocayatak become grade-separated. The airport leg therefore gets faster, but it stays a state road with junctions and local traffic.

Gazipaşa was once on the route. The motorway's 2018 environmental impact assessment ran the line on to Gazipaşa, and the project now ends at Km 136 at KGM's request. The tender-stage route ran from Km 0, south of Ekşili in north-west Antalya, to Km 155.6, east of Alanya. The ESIA's traffic study cites the national 2053 Transport Master Plan, which lists an Alanya-Silifke motorway for 2035. Mevlüt Çavuşoğlu, an AK Party member of parliament for Antalya, said on 6 September 2026 that an extension to Gazipaşa is planned, without giving a route, a cost or a timetable. For an owner in Gazipaşa, the motorway's benefit ends at Telatiye, and the choice between Gazipaşa and Antalya airports remains a separate question from the motorway.

When will the Antalya Alanya highway open?

The contract requires the Antalya Alanya highway to open within 36 months of the financing signed on 6 October 2025, which means by October 2028; an opening before May 2028 is a political target, not a contractual date. Physical progress reached 30% on 25 August 2026, according to Transport and Infrastructure Minister Abdulkadir Uraloğlu.

The project's dates run from the public interest decision to the contractual opening.

The contract clock gives a simple test of both dates. On 25 August 2026, 10.6 of the 36 months had passed, 29% of the time, against 30% physical progress, so the project was running at contract pace. Finishing the remaining 70% by October 2028 needs about 2.8 percentage points a month, the same rate as so far. Opening by May 2028 needs about 3.5 points a month, roughly a quarter faster. Tunnels and viaducts take longer than paving, so physical progress rarely moves in a straight line, and the arithmetic shows direction rather than a forecast. Ali Çetin put the third tunnel's completion in October 2026 and the last two in 2027.

For a buyer, the dates translate into seasons. A viewing trip in 2027 shows a construction corridor, not a road. If the political target holds, summer 2028 is the first season with the motorway. If the contract date holds, the first full summer is 2029.

How long will Antalya Airport to Alanya take once the highway opens?

Expect a trip about 30 minutes shorter than today, not a 36-minute trip: the lenders' traffic study models a saving of about 30 minutes for long-distance drivers, because the D-400 legs at both ends of the motorway remain. Even at the legal maximum on every leg, a drive from Antalya city centre to the D-400 at Telatiye takes just over an hour.

The trip from Antalya splits into four legs before the final drive to an address.

The 42 km first leg is KGM's road distance from Antalya to Serik. Antalya Airport lies north-east of the city centre, on the Serik side, so the airport leg is somewhat shorter. Those times are a floor, not an estimate, because nobody drives a busy state road at a constant 110 km/h.

The motorway does not make the trip shorter in kilometres. Its own roads, from the D-400 at the Serik trumpet to the D-400 at Telatiye, add up to about 100 km. KGM's distance table leaves about 96 km of D-400 between Serik and Alanya (138 km minus 42 km). The motorway saves time by being faster and free of settlements, not by being more direct.

The traffic study attached to the ESIA puts the saving at about 30 minutes for long-distance users and expects local traffic to stay on the D-400. Set against the 2 to 2.5 hours an Antalya Airport transfer to Alanya takes today, that points to roughly 1.5 to 2 hours from Antalya Airport to central Alanya once the motorway opens. The saving is likely to be largest in July and August, when car traffic on the D-400 runs about 40% above its annual average. For a Mahmutlar owner, the drive after Telatiye continues on the D-400 into Alanya and then on the Eastern Ring Road from Hasbahçe.

Will the speed limit on the highway be 140 km/h?

Very likely, for cars: KGM's own speed limit table sets 140 km/h for cars on motorways operated under the build-operate-transfer model, against 130 km/h on motorways that KGM operates itself. The Interior Ministry announced on 30 June 2022 that motorways under construction or yet to be designed would open with the 140 km/h limit. The Aydın-Denizli motorway, built under the same model, opened its first 80 km on 3 November 2023 with a 140 km/h maximum.

The ESIA uses 140 km/h as the main line's design speed and 110 km/h for the link roads, and leaves the posted limit to Turkish law. The final signage therefore comes at opening. At 130 km/h, the main line would take about 39 minutes instead of 36, so the speed limit question is worth about three minutes, a small fraction of the time lost on the D-400 legs.

Why is "2.5 hours to 36 minutes" the wrong comparison?

The official headline sets the time for part of the new trip, the 84 km main line, against the whole of the old trip, city to city on the D-400. The two figures share no start point and no end point, so their difference is not a saving anyone will experience.

The D-400 explains where the real saving comes from. KGM's 2023 traffic counts on the sections that compete with the motorway range from 28,097 to 54,315 vehicles a day, and the traffic study rates most of those sections C or D on the A to F level of service scale that traffic engineers use. Car traffic runs about 40% above the annual average in July and about 25% below it in January. At the legal maximum, the 96 km of D-400 between Serik and Alanya would take about 52 minutes, against about 45 minutes for the motorway's 100 km. The motorway's advantage is therefore escaping congestion, settlements and junctions, not a higher speed limit.

How much will the Antalya Alanya highway toll cost?

No tariff exists yet, because KGM publishes it at opening; the only fixed reference is Limak's winning bid of EUR 0.0598 per km in December 2023, a figure before VAT and before the contract's indexation. The motorway works as a closed system. Every link road carries a toll station equipped for HGS (Hızlı Geçiş Sistemi, Turkey's electronic toll tag), with staffed booths for cash, and KGM may add a main-line toll barrier at Km 52.

Tolls in a closed system follow the distance between the entry and exit stations, which the traffic study measures for each pair.

The traffic study's own 2028 model uses EUR 6.12 for a full-length trip, a figure the study treats as a modelling input, not a tariff. A family flying into Antalya four times a year drives eight one-way trips, which comes to about EUR 42 at the December 2023 bid before VAT. A holiday-let owner who drives 30 one-way airport runs in a season pays about EUR 159 on the same December 2023 basis. The D-400 remains toll-free for drivers who would rather save the toll than the time.

Who pays if fewer drivers use the highway than expected?

KGM does: the contract guarantees the operator toll revenue for 100,000 car-equivalent vehicles a day, and when traffic falls short, KGM pays the difference. The traffic study values the guarantee at EUR 729,560 a day, calculated as EUR 0.0598 times 122 km times 100,000 at the December 2023 bid.

The same study forecasts 25,007 car equivalents a day in 2028, rising to 35,574 in 2030 and 60,372 in 2040. Its own conclusion is that the guaranteed level is not reached within the period it analyses. In the first year, forecast traffic is about a quarter of the guaranteed level, and the difference is paid from the public budget. For a driver, the arrangement has two plain consequences: the operator has no commercial reason to cut tolls to attract traffic, and the free D-400 alternative stays in place.

What changes for each Alanya neighbourhood?

Western Alanya gets the motorway's three junctions and most of its construction work, while eastern Alanya, from Oba to Kargıcak, gains only through the combination of the motorway, the D-400 from Telatiye and the Eastern Ring Road. The figures come from the ESIA and the Resettlement Action Plan, both published by the project company.

Eleven parts of the Alanya district line up differently against the motorway.

A neighbourhood in the expropriation column contains affected parcels; the listing does not mean every property in it is affected. Avsallar shows why the parcel count alone misleads. Only 6 parcels are listed, but they cover about 61 hectares, almost all of it state forest. The same neighbourhood hosts the construction camp, two spoil areas and the nearest asphalt plant, so Avsallar's exposure is construction traffic until 2028 rather than land loss.

How does the Alanya Eastern Ring Road fit with the highway?

The Eastern Ring Road is the second half of the journey to eastern Alanya: it starts at Hasbahçe, runs 12 km to Mahmutlar through three tunnels, and keeps traffic from the motorway off the D-400 through Oba, Cikcilli and Kestel. The Ministry of Transport and Infrastructure opened the Hasbahçe to Mahmutlar section on 20 December 2025, out of a planned total of 15.2 km.

The opened section carries three twin-tube tunnels: Oba at 653 m, Dim at 1,692 m and the Mahmutlar cut-and-cover tunnel at 363 m. The ministry expects the completed ring road to cut the crossing of Alanya from about 35 minutes to 10, on a route that carries about 33,000 vehicles a day. The last 3.2 km, from Mahmutlar to Kargıcak, had not opened by October 2026. A zoning rearrangement over 700 decares was planned in December 2025, and KGM scheduled expropriation talks for the Hasbahçe to Kargıcak line in Mahmutlar for 8 July 2026.

The two projects do not touch. Between the motorway's end at Telatiye and the ring road's start at Hasbahçe, traffic uses the D-400 through western Alanya. For a Kestel owner in 2029, the route from Antalya Airport is therefore D-400 to Serik, motorway to Telatiye, D-400 through the western city, and the ring road's tunnels to Kestel.

Will the D-400 coast road get quieter?

Quieter, not quiet: the traffic study expects about 44% of the traffic on the competing D-400 sections to move to the motorway at opening and about 72% by 2040, which still leaves about 23,000 vehicles a day on the D-400 in 2040. Local traffic, the trips between neighbourhoods and towns along the coast, stays on the D-400 throughout.

Heavy vehicles show the change most clearly. Lorries and buses make up about 15% of today's D-400 traffic, and the study expects them to be 27% of the motorway's traffic in 2028. The through lorries that now pass seafront blocks in Avsallar, Konaklı or Mahmutlar are the traffic the motorway is most likely to take. A D-400 apartment on the coast keeps its local traffic, but may lose part of its lorry traffic.

Will the highway raise property prices in Alanya?

No study measures a price effect from the Antalya Alanya highway, and the project's own impact assessment, which expects values to rise near junctions, attaches no figure to that expectation. The ESIA states that the project will contribute to rising property values, especially near motorway junctions, with potential gentrification in some areas. The same document expects speculative development and land-use change, especially around new exits and service areas.

The ESIA is an environmental and social assessment written for lenders, not a valuation. In the Alanya district, the places its description fits are the Alarahan, Konaklı and Alanya Batı junctions and the service area planned at Km 135.5 in Toslak. What can be measured today points both ways. Access arrives in 2028 at the earliest. Construction traffic, quarries, a camp and spoil areas arrive now in western Alanya. The 2040 noise model predicts limit exceedances in Çakallar, Emişbeleni and Konaklı.

A listing that sells "minutes from the new motorway" prices in a road that was 30% built in August 2026. Compare such a listing with similar units sold before the motorway became a selling point; the method for building that comparison is set out in the guidance on how much of an Alanya asking price is negotiable. An apartment in Avsallar, for example, sits between two junctions about 16 km apart, so "near the motorway" there means a view of the line rather than an entrance to it.

What happens if you already own land on the highway route?

KGM first offers to buy the land at a price set by its own valuation commission, and if no agreement is reached, a civil court sets the price and registers the land to KGM; in Alanya, the negotiation round is planned for the end of 2026. In September 2025, KGM had not yet started negotiations in any Alanya neighbourhood. The project's July 2026 land acquisition guide targets the third quarter of 2026 for Km 116 to 141 and the end of 2026 for the Alanya meetings.

The Alanya district carries a large share of the corridor's land. The Resettlement Action Plan lists 1,080 parcels in 11 Alanya neighbourhoods, 597 of them privately owned. Of those parcels, 109 carry houses and 210 carry greenhouses. That puts 30% of the corridor's parcels, 47% of its parcels with houses and 60% of its parcels with greenhouses in Alanya.

Expropriation Law No. 2942 sets the steps and the deadlines.

1. KGM asks the land registry to annotate the expropriation decision on the title (Article 7). A sale is still possible, but the registry reports the new owner to KGM, and the annotation lapses if no court case is filed within six months.
2. KGM sends the owner a registered letter inviting a negotiated sale (Article 8). The owner has 15 days from notification to apply, and the agreed price cannot exceed the valuation commission's estimate.
3. KGM pays and registers the land within 45 days of a negotiated agreement.
4. KGM applies to the civil court of first instance when no agreement is reached, and the court sets the price and registers the land to KGM (Article 10). The law gives a first hearing within 30 days; the Resettlement Action Plan says the court process takes about two years in practice.
5. KGM can use urgent expropriation under decision No. 9708: the court sets the value within seven days, KGM deposits it and takes possession, and the possession order is annotated on the title as a ban on transfer (Article 27).
6. KGM's decision can be challenged in the administrative court within 30 days of the court's notice, and the owner can ask in writing within 30 days for an unusable leftover piece of a parcel to be expropriated too (Articles 12 and 14).

The project's lenders require more than Turkish law provides. The Resettlement Action Plan, prepared to the International Finance Corporation's Performance Standard 5, admits that the law pays neither full replacement cost, nor transaction costs, nor tenants. The project company covers part of the gap from a dedicated fund.

The EUR amounts are the plan's figures as of September 2025. They are lender conditions accepted by the project company, not rights under Turkish law, and claims go through the project's community liaison officers rather than the court.

Timing rules cut off late improvements. For road projects, the public interest decision is posted at the muhtarlık (neighbourhood headman's office) for 15 days, and buildings or trees added after that posting are not compensated for five years (Article 25). The Resettlement Action Plan applies its own cut-off date in each settlement, the date of its asset inventory.

Owners who live abroad face the tightest deadline. The plan contains no separate procedure for foreign owners, and KGM identifies owners and addresses from land registry, tax and population records. An owner who misses the 15-day window in Article 8 loses the negotiated route and goes to court; where no address is found, the court notifies by public announcement and blocks the compensation in the bank. Keep the address on Turkish tax and registry records current, and give a representative in Turkey a power of attorney that covers expropriation and court matters. The plan covers power of attorney costs without limit, and the YİMER line, 157, takes complaints from foreign nationals. The project's own grievance line is 0850 202 07 07.

What should you check before buying near the highway route?

Check six things before buying within sight of the route: the title deed, the parcel's distance from the alignment, the construction sites nearby, the noise prediction, the setback rules and the zoning around the junctions.

1. Request the tapu kayıt örneği (title deed registry extract) and look for a kamulaştırma şerhi (expropriation annotation). An annotation does not block the sale, but it means KGM is acting on the parcel. Its absence proves less than it seems: an annotation lapses after six months if KGM files no court case, and in Alanya the negotiation round is still ahead.
2. Locate the parcel against the alignment, not against a sales map. The ESIA records the route passing directly over the nearest buildings of Çakallar, Alara, Avsallar, Akdam, Türkler, Soğukpınar, Emişbeleni, Toslak and Konaklı-Telatiye.
3. Map the construction sites within reach of the address. Saburlar, Karamanlar and Soğukpınar quarries, Camp 3 with its plants at Km 124+300, and spoil areas in Avsallar, Akdam, Türkler and Payallar operate until the road opens. The ESIA rules out surface blasting within 100 m of settlements where another method works, and records the condition of buildings within 100 m of the route before and after construction, so ask whether that survey covered the building.
4. Ask about noise at the specific address. The ESIA recommends a 3 km, 4.5 m high barrier in Emişbeleni, subject to KGM approval and monitoring. Çakallar and Konaklı also exceed the noise criterion in the model without a barrier, and Toslak, Türkler, Soğukpınar and Elikesik had no measurement point at all.
5. Confirm the setback. In zoned areas, the Resettlement Action Plan records a building line of 5 m from the road boundary for housing and 25 m for commercial buildings, and no separate protection strip beyond the expropriation corridor. A house just outside the corridor can therefore sit lawfully close to the carriageway.
6. Obtain the imar durumu (zoning status certificate) from the municipality and ask whether any plan change is pending around the Alarahan, Konaklı and Alanya Batı junctions or the Toslak service area.

A resale apartment on the coast in Konaklı and a greenhouse plot in Toslak need different subsets of the six checks. The apartment mainly needs checks 4 and 6. The plot needs all six, starting with the annotation, because Toslak has 167 parcels in the expropriation plan.
