To counteract traffic grid-lock in Oslo, Norway, city planners decided to upgrade the entire road network and build a ring road at a cost of $1300 million. Begun in July 1988, it is scheduled for completion by 2001. This article describes the construction methods utilized in the Granfoss section of the ring road, due to be finished in October 1992. The drill and blast-driven tunnels, which at one point pass a mere 2m below a river, will use a special waterproofing membrane to prevent ice formations on the tunnel sides and road surfaces.
