Antalya–Alanya Highway: The highly anticipated “Antalya–Alanya Highway Project,” which will speed up transportation between Antalya and Alanya, is officially underway. According to the General Directorate of Highways, the project was tendered on December 15, 2023, under the Build-Operate-Transfer model, and the implementation contract was signed on October 14, 2024. The process is now advancing in line with the official schedule.

The Ministry of Transport and Infrastructure had announced that the groundbreaking ceremony would take place on Friday, July 25, 2025. The Antalya Governorship later confirmed that the ceremony was held last month, with Minister of Transport and Infrastructure Abdulkadir Uraloğlu and Minister of Culture and Tourism Mehmet Nuri Ersoy attending. This marks the official start of construction.

Project Scope: A 122 km Modern Network

According to the official project brief, the highway will feature 84 km of 2×3-lane main route and 38 km of 2×2-lane connection roads, totaling 122 km. The route will start at Serik Junction, follow the foothills of the Taurus Mountains, and end at the Alanya Junction north of Konaklı. This design aims to divert traffic away from the D-400 coastal road, reducing congestion in the heart of tourism hubs.

The project’s FAQ notes that the construction period is planned to last approximately 3 years. This timeline suggests that, following the groundbreaking, viaduct and tunnel works will progress in a coordinated manner to meet the schedule.

Key Benefits for the Region

• Shorter travel times, more comfort: Peak-season congestion will be reduced as main lanes and connection roads are separated, allowing for significant time savings on trips between Antalya city center, Serik, Manavgat, Side, and Alanya. The Highways Directorate emphasizes that such investments lower fuel consumption and vehicle maintenance costs, while reducing noise and emissions for environmental benefits.
• Boost for tourism and trade: Improved access to airports and logistics hubs will accelerate supply chains for hotels, malls, and new investments. The Ministry highlights that the project will directly contribute to touristic, economic, and social growth.
• Safe and uninterrupted travel: Multi-lane standards, modern interchanges, tunnels, and viaducts will enhance traffic safety and minimize “bottleneck effects” during seasonal peaks. The Governorship also stated that the project will provide a faster, safer, and uninterrupted corridor.
• Relief for the D-400 road: The highway will serve as a load-reducing alternative to the D-400 coastal road, easing city traffic and improving east-west transit in Alanya with complementary bypasses and connection roads.

Why It Matters Now

The number of vehicles and tourism mobility between Alanya and Antalya grows each year, causing frequent bottlenecks on the D-400. With the new highway, through traffic will bypass city centers, heavy vehicles will shift to the new route, and urban quality of life will improve. As officials underline, the time and cost savings will also strengthen the region’s competitiveness.

“When Will It Be Completed?”

Based on the information shared after the groundbreaking, the construction period is planned for about 3 years. This means that (taking the July 25, 2025 groundbreaking date as a reference) phased openings could start around 2028. Official announcements and progress reports will clarify the exact schedule as construction advances.

Bottom Line

The Antalya–Alanya Highway promises a permanent solution to chronic traffic congestion while providing fast and safe access for tourism and trade. With its multi-lane design, modern interchanges, and connection roads, the project will deliver savings in fuel, time, and emissions. Now that construction has begun, this investment is set to transform the eastern corridor of Antalya Bay into a safe, fast, and sustainable transportation route.

Note: Local municipalities’ complementary bypass and connection road projects (such as East/West ring roads) will further enhance the impact of the highway once completed.
