The Ministry of Infrastructure has unveiled plans to modernize the main highway leading out of Tbilisi, transforming it into an eight-lane roadway with two parallel tunnels to be constructed under Koshigora. The project aims to address growing traffic congestion and improve connectivity between Tbilisi and the country’s western regions. An Environmental Impact Assessment (EIA) and detailed design documentation have been submitted to the Department of Environmental Supervision, which is currently reviewing the proposal. Citizens will have the opportunity to submit comments and feedback on the project in the coming months.
According to the submitted plans, Davit Agmashenebeli Alley will be expanded, and an overpass will be built parallel to the Agrarian University and the Georgian national team training base. This new section will connect to the twin tunnels located near the Škoda Center. The tunnels will be approximately 1.6 and 1.9 kilometers long and will connect directly to a new bridge, creating a bypass route that allows traffic to flow toward Mtskheta without entering the city.
Overall, the modernization will cover an 11-kilometer section of the Tbilisi exit road, fully converting it into an eight-lane highway. The project is being implemented by the Georgian Roads Department, with feasibility studies conducted by SMEC International, an Australian engineering firm. The goal is to improve traffic flow and ensure long-term efficiency for one of the busiest road segments in the country.
The design documentation notes that the current four-lane road, which serves around 60,000 vehicles daily, is no longer adequate for increasing traffic volumes. Studies conducted by SMEC International found that even a six-lane expansion would not be sufficient in the coming years. Based on projected traffic growth, engineers concluded that the highway must be expanded to at least eight lanes to prevent future congestion and ensure the sustainability of Georgia’s main transport artery.
