The tunnel on the first round is the longest road tunnel in the World, 24509 meters. Here's a time lapse video from 2019 when I drove through it. I came out from that end which was in the game. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-4BxM2zzHCXw.html
I had big luck with Lærdalstunnelen and Nygårdstunnelen, but I had to search the others a little. I should have been a lot faster at least in Kristiansand where I used over a minute.
