S9 highway (Georgia)


The Georgian S9 route to the S4 Highway near Rustavi. The bypass intersects with the S5 "Kakheti Highway" near the Tbilisi International Airport and is part of the European E60 and Asian AH5 and AH81 routes. Transit traffic is mandated to take the bypass around Tbilisi.
The bypass is entirely two lane and has a limited number of junctions, some of which have grade separation, although the Mtskheta end of the bypass passes through residential area. The northern terminus is located in the Mtskheta-Mtianeti region, while the northern part of the bypass is in the Tbilisi capital region and most of the bypass is located in the Kvemo Kartli region.

Background

The S9 Tbilisi Bypass was commissioned in 1996, when the Georgian road numbering system was revised to replace its old Soviet system.

Future

Feasibility and design studies into the upgrade of the S9 Tbilisi Bypass to four lane motorway standards have been finalized in 2020. Financed by the Asian Development Bank the studies included a northern extension via Natakhtari to Zhinvali on the left bank of the Aragvi river.
