Georgian S12 Samtredia - Lanchkhuti - Grigoleti highway is under upgrade with major redesign of the route within the East-West Highway project. The map includes portions of the S1 and S2 redesign as they are related.
The pink line represents the (old) S12 route, the dashed red lines are the new S12 motorway sections under construction, and the straight red lines are the opened motorway section between Japana and Lanchkhuti (2020) and Khajalia and Grigileti (2022). 
The bright blue line represents the route of the S2 since the 2018 opening of the Kobuleti Bypass. The dark blue line is the S2 motorway section under construction which will connect fluently with the S12 motorway. 

The dots are (proposed) grade separated exits in the new two/four-lane expressway sections.
