Tunnel upgrade Oslo E18 Sjølyst and Bygdøylokket

Kort beskrivning

When the E18 was built, Hoffselva was led in a pipe under a road. The road has since had settlement damages above the pipe and the pipe's capacity is now insufficient. The pipe will therefore be dug up and replaced with a new culvert construction that crosses under Sjølystlokket. Due to the geographical proximity, the establishment of a new culvert for Hoffselva and the renovation of Bygdøylokket and Sjølystloket will be carried out in a joint contract. The annual daily traffic count on this part of the E18 is approx. 77,000 vehicles per 24 hours (2019). In addition various signing work on the E18 is included in the contract, from Lysaker to Filipstad, as well as a stretch on Ring 3 from Økern to Ryen, and by Storo/Sinsen.
