E18 Retved-Vinterbro bridges

Mannvit was a consultant for the design of various bridges in Norway, over and near the E18 motorway between Oslo and Stockholm. The E18 Retved-Vinterbro project involves planning and designing the final part of the new four-lane H9 motorway from the Swedish border to Vinterbro, to the east of Oslo.


Planning and designing of bridges

Longest bridge

“It is an interesting challenge to participate in the design of eleven bridges totalling 1,680 m in length, the shortest 25 m and the longest 345 m. This is probably more bridge building than has been built in Iceland in the past few years.”
