This report presents analyzes and findings related to effects and consequences of capacity reduction from four to two lanes in the Bryn-tunnel. The report addresses the situation before the capacity was reduced as well as the situation when the capacity was reduced. Road users adapted to the new situation in ways resulting in significant reductions in traffic volumes in the tunnel and on this part of the road system. In other parts of the road system, we find only minor changes in traffic volumes and speeds. Travelers adapted by choosing other routes, other means of transport, other time of travel and more frequent use of home office. The delays and adaptions have caused disadvantages to all types of travelers, but not large negative consequences. A main conclusion is hence that halving the capacity of one of Norway's heaviest traffic links did not cause crisis or chaos.
