Nordhordland Bridge set to NOK 20 for five years, and then after the completion of the first stage, the toll will be NOK 40 for fifteen years. The toll plaza is scheduled to reopen in 2013. Among the projects is a new four-lane Nyborg Tunnel which will shorten the distance of E39 from the bridge with the motorway at Nyborg in Bergen.

It is long, of which the pontoon section is long. The cable-stayed section consists of a
Pontoon effect Pontoon effect The pontoon effect refers to the tendency of a vessel whose flotation depends on lateral pontoons to capsize without warning when a lateral force is applied. The effect can be sudden and dramatic because pontoon boats usually cannot rely on the righting effect of a keel (which contains ballast). The vessel is stable and self-righting up to the point that the centre of gravity shifts past the centre of buoyancy of the ship and the vessel rapidly capsizes. The pontoon effect is theoretically possible whenever the vessel's entire weight exceeds the buoyancy of the pontoon(s) on either side.
