Road tunnel extension for Norway capital Oslo?

Plans are being worked on in Norway for a new tunnel development for part of capital Oslo’s ring Road. The Norwegian Directorate of Public Construction and Property (Statsbygg) has proposed that part of ring road Ring 1 in Oslo should be placed underground where it runs close to the government quarter. The proposed changes are part of a risk assessment for the government quarter decreed by the Defence Estates Agency (Forsvarsbygg). Knut Jørgensen, project manager in Statsbygg, says that Statsbygg recommends that the stretch between the Hammersborg and Vaterland tunnels should be covered. The project would be likely to cost around €173.06 million (NOK 1.6 billion) and would also help improve traffic flow.
