The Georgian S6 route (Georgian: საერთაშორისო მნიშვნელობის გზა ს6, Saertashoriso mnishvnelobis gza S6, road of international importance), also known as Ponichala–Marneuli–Guguti (Armenian border), is a "road of international importance" within the Georgian road network and runs from Ponichala in Tbilisi via Marneuli and Bolnisi to the border with Armenia near Guguti over a distance of 98 kilometres (61 mi).[1] After crossing the Georgian-Armenian border the highway continues as M3 to Vanadzor and Ashtarak, northwest of Yerevan.

The S6 highway is entirely part of European E117 route xwhile the Ponichala to Marneuli segment is also part of the Asian AH81 highway. The route connects with the Georgian S4 highway at its northern terminus in Ponichala and with the S7 highway in Marneuli. Furthermore, the road is mostly located in the Kvemo Kartli region as a two lane road, while the three kilometers in Ponichala are located in the capital region with four lanes.

Background

Since the early 1980s the current S6 route was referred to as A304 within the Soviet road network, which extended to Gyumri via Tashir in the Armenian SSR (nowadays Armenian routes H31 and M1). In Marneuli the A304 connected with the A310 highway (Georgian S7 highway). Prior to the 1980s the route was one of the few Soviet roads to have a number, highway 16, which ran from Vladikavkaz (Ordzhonikidze) via Tbilisi to Gyumri (Leninakan).

In the first years since Georgia regained independence in 1991, the Soviet route designations were maintained until the road numbering system was revised in 1996 and the "roads of international importance" (S-)category was introduced. Then the "S7 Ponichala–Marneuli–Guguti (Armenian border)" replaced the A304 designation.[2]

The S6 is part of the most popular route between Tbilisi and Yerevan, with most traffic taking the Georgian S7 highway in Marneuli which offers alternative routes within Armenia.

Future

As of 2021 there are no plans to upgrade the S6 highway to higher standards or capacity. Most noteworthy is the 2020 rehabilitation of 13 kilometres (8.1 mi) between Saparlo and Guguti (Armenian border). This section was in a very poor condition.[3]

Route

The S6 highway branches off the S4 highway in Ponitchala at the south side of Tbilisi. For the first 4 km within the Tbilisi capital region the road has 4 lanes with a median. Upon entering the Kvemo Kartli region it narrows to a 2 lane highway. Until the town of Marneuli the road passes a few villages, while at Koda the important Sh31 regional highway to Tsalka and Ninotsminda branches off. The centre of Marneuli is an important crossroads. The S7 highway to Armenia begins at the central roundabout in town. This is the most popular way to Armenia from Tbilisi. The S6 continues to Bolnisi and passes through a string of villages. After Bolnisi the road turns south towards Armenia and passes some important historic sites in Georgian history.

Intersections

The entire S6 route overlaps with E117.
