In May, 2005 in Baku the Azerbaijan, Georgia and Turkey Presidents signed the tripartite declaration according to the construction project of a railway main line Kars - Akhalkalaki - Tbilisi - Baku. The general extent of the highway is 105 kilometers. From them the 76 kilometers will pass on the territory of Turkey and 29 kilometers on the territory of Georgia. For the Georgian party besides especially economic benefit the railway main line has also a certain political value. Russia bypassing Georgia can cut through the road to Europe for the trains. It is planned that the railway main line Baku-Tbilisi-Kars will be started in 2015.
