Preparation of a planning programme, development plan and construction plan - new thirteen bridge in Øyer municipality - Stage 1

Description du marché

Thirteen bridge (built in 2012) collapsed 15 August 2022. The bridge is connected to the east and west side of Thirteen together and it is a part of county road 254. The bridge was a truss bridge made of steel and wood. The main span was 70 metres and a total of 148 metres of bridge with two lanes and pavements was initiated. Temporary bridge, stand-by bridge loaned by the Norwegian Public Roads Administration, came into place in the summer of 2023. Temporary bridge has 10 years approval. A feasibility study was first prepared, of which four different placements were assessed. Here a new bridge was adopted near the existing bridge. The location had to be directly upstream or downstream, as the existing location was "seized" by a temporary bridge. The draft project provided further details on the feasibility study. The recommendation from Cowi was submitted in January 2024. The sketch project assessed 3 different routes in connection with the existing bridge, as well as 3 different bridge types. The recommendation was a steel and concrete work bridge, with a culvert over the E6. The recommended route was straight upstream for the existing bridge. The feasibility study and sketch project are included in the tender documentation.
