A20 is indicated on OSM but not on GM/GSV. GSV is from 2012
(all over Lithuania).
According to
wegenwiki, the bypass was built by the municipality but rededicated to A20 in 2014. I'll go with OSM and add the route.
According to
wegenwiki,
wikipedia and OSM, there is also an
A21 at the border to Russia. The construction of the bypass was started in 2014 and it's (not yet) indicated on GM/GSV. It was
completed in August 2015 but not yet opened because the Russian section is not yet completed. Not adding.
K202 - continues north
The only sign I found is
this one on 2012 GSV at the current end. I guess it was rededicated or just signed after 2012.
wikipedia also indicated that it ends at Kirtimai and has a length of 27km. I'll extend it.
K219 - Pik -> R2703?
I couldn't find R2703 on OSM/GM/GSV. What's your source?
Edit:
K145 - R2001 needs moving
Really? All streets are one-way streets.
