It runs from Kaunas to the Polish border, toward Suwałki and ultimately Warsaw.

A section of the A5 highway - Kaunas-Marijampolė, has been upgraded to a motorway, accessed only via grade-separated junctions, and completed in 2017/18.

It is the first motorway built after Lithuania entered the European Union in 2004.

The entire reconstruction up to the Polish border is due to be completed by the end of 2025.

It is a segment of the part of E67 named "Via Baltica", that spans the eastern shore of the Baltic Sea.
