Several tunnels in Hordaland, Sogn and Fjordane, also Rogaland closed during the night in the near future.
For the next two weeks Mundalsberg and Bjørsviktunnel on E39 in Lindas Hordaland are closed every night except Sundays, according to NRK news.
The work is part of a larger Statens Vegvesen project where a series of tunnels on the west coast will be upgraded to satisfy EU rules.
Also four tunnels on the E16 in Sogn and Fjordane will be shut at night, as part of the same project.
In addition Byfjord Stavanger is closed. Proposals state a column could run every hour through the night.
After the Road Administration is finished with the mentioned tunnels it will be a small step towards the 148 tunnels to be upgraded.
