The Turkish Ministry of Transport has announced a significant milestone in regional infrastructure development, confirming that the Antalya — Alanya high-speed highway is now 30% complete. This ambitious project aims to modernize the transport corridor along the southern coast of Turkey, providing a high-capacity alternative to existing coastal roads. Once finalized, the new route will fundamentally alter the logistics of the Turkish Riviera, facilitating faster movement between major tourist hubs and urban centers.
Technical Specifications and Infrastructure Scope
The project spans a total length of 122 kilometers, starting from the Serik junction, passing through the Manavgat district, and terminating at the western Alanya junction located in the Konaklı district. To navigate the complex regional topography, the engineering plan incorporates several large-scale structures designed to maintain high speeds and safety standards.
The infrastructure requirements for the route include:
- Five specialized tunnels to bypass mountainous terrain.
- Sixteen viaducts designed for structural durability and elevation.
- Seven strategically located interchanges to manage local traffic flow.
Under the current technical guidelines, the permitted speed limit for the main arterial road is set at 140 km/h, while the connecting access roads will support speeds of up to 110 km/h. These speed limits are among the highest in the Turkish road network, reflecting the highway's classification as a premier high-speed transit route.
Economic Impact and Travel Efficiency
The most notable benefit for travelers and residents alike is the drastic reduction in transit times. Currently, the journey between Antalya and Alanya can take up to 2.5 hours depending on seasonal traffic congestion. Upon commissioning, the high-speed highway is expected to shorten this duration to approximately 36 minutes.
Regarding the financial model, the highway will operate as a toll road. Current estimates suggest the cost for a full trip will range between 350 and 450 lira, payable through the existing HGS (Fast Pass System). The HGS system uses electronic stickers or tags to automate payment, reducing wait times at toll plazas.
The completion of this highway is expected to bolster the tourism sector by making the eastern regions of the Antalya province more accessible to international arrivals from the airport. Furthermore, the diversion of transit traffic from the coastal D400 highway may lead to improved safety and reduced emissions in residential beach areas. As of August 26, 2026, construction continues according to the scheduled timeline provided by transport authorities.
