Transport Infrastructure Projects Çanakkale Ezine Ayvacık Küçükkuyu Road

Çanakkale Ezine Ayvacık Küçükkuyu Road

A divided road providing safe, uninterrupted transport between Çanakkale's coastal settlements

Phase 1 construction: 2011 to 2013; Phase 2: 2013 to 2017; Phase 3: 2017 to 2022

Çanakkale Ezine Ayvacık Küçükkuyu Road

General Information

Location

Çanakkale, Balıkesir and İzmir route, Türkiye

Employer

Karayolları Genel Müdürlüğü

Project Scale

84 km to divided road and hot mix asphalt standards (BY-BSK), 2x2 lanes

Project Duration

Phase 1 construction: 2011 – 2013Phase 2 construction: 2013 – 2017Phase 3 construction: 2017 – 2022

Principal Engineering Structures

2 twin-tube tunnels1,693 m Assos Tunnel + 4,017 m Troya Tunnel = 11,420 m in total3 grade-separated interchanges6 bridges21 at-grade junctions

Safety

Upgrading the Çanakkale İzmir road from single carriageway surface treatment (TY-SK) to divided road hot mix asphalt (BY-BSK) increased width from 8.00 m to 26.00 m. Geometric improvements enhanced driving safety and comfort. Completed works minimized potential accidents and fatalities.

Çanakkale, whose glorious resistance holds a place in our nation's epic history, continues developing through its historical fabric, coastal, cultural and thermal tourism, agriculture and related industries. The city is an important crossing linking Asia and Europe and connecting the Black Sea and Marmara Sea to the world.

Architectural and Engineering Details

Numerous major and minor engineering structures were designed and implemented with modern techniques respecting Çanakkale's history and nature. Between Ayvacık and Küçükkuyu, the twin tube Assos (1,693 m) and Troya (4,017 m) tunnels, totaling 11,420 m, and landscaping minimized impacts on the unique Kaz Mountains landscape containing ancient Gargara. The works added lasting value to regional infrastructure.

Technologies and Innovations Used

Special junction and tunnel designs addressed route requirements and geographical challenges, with modern landscaping and traffic arrangements throughout.

Project Stages

Construction Stages

Stage 1: Çanakkale Ezine Section

Stage 2: Çanakkale Ezine Ayvacık Section

Stage 3: Ayvacık Küçükkuyu Section (Assos and Troya Tunnels

Solutions

Modern engineering suited to terrain and environment, including grade separated intelligent interchanges and tunnels, combined with divided road standards to provide uninterrupted transport, improve safety and eliminate traffic problems, especially in summer.

Sustainability

Economic and Social Impact

Reduced lost working time, fuel use and carbon emissions saved TRY 463 million annually, contributing to the national economy. Opening improved access to regional tourism and trade, stimulating the local economy.

Sustainability and Environmental Sensitivity

Construction considered all environmental impact assessments. Opening as a divided road targets decades of service, creating an environmentally sensitive transport network in fuel consumption and carbon emissions.

Of the 84.00 km road connecting Çanakkale to Balıkesir and İzmir, 74.37 km opened in the first two phases. Assos and Troya tunnels in phase three prevented Kaz Mountains problems caused by summer traffic and winter weather. Improved physical and geometric standards increased route safety and driving comfort.
