A6 highway (Lithuania)
The speed limit for most of the length of A6 is default 90 km/h (outside city limits). The section from Kaunas to Jonava has been upgraded to a dual carriageway with at-grade junctions and traffic-lights. The remaining sections are roads with one lane in each direction, leading through towns like Ukmergė, Utena and Zarasai.
A6 autostrada (Poland)
In the years after the war the damage caused by wartime demolitions was repaired, though not completely as some Oder bridges were only rebuilt with a single carriageway. After that, the motorway did not see any significant upgrades or reconstruction until the 1990s. As a result, it fell far short of modern standards, and so on some maps it is not marked as a motorway (in whole or in part). Work on upgrading the highway to modern standards began in the late 1990s, starting with the full rebuilding of Oder bridges. At present, the full 22 km from the German border to the junction with national road 10 has been reconstructed, with the last stretch fully opened on 26 September 2007. However, some interchanges are still awaiting upgrades, and a major interchange with the express road S3 opened in 2010. Additional was upgraded in June 2014 and was officially redesignated as A6. In the more distant future A6 may be extended north to Goleniów and reach a length of about .
