Sammendrag

This end-report summarizes the results of analyses of adaptions to, and effects and consequences of a capacity reduction from four to two lanes in the Bryn-tunnel in 2016, and of the tunnel regaining full capacity a year later in 2017. The delays and adaptions caused disadvantages to all types of users, but not large negative consequences. A main finding is hence that halving the capacity of one of Norway's heaviest traffic links did not cause crisis or chaos. We discuss what we can learn from these findings. Thorough descriptions of knowledge-base, theoretical framework, methods, analyses and findings are available in a documentation report (TØI-report 1733/2019).
