Grenland Bridge (Norwegian: Grenlandsbrua) is Norway's highest cable-stayed bridge with a tower height of 168m (551feet). The bridge, which opened in 1996, is part of the European Route E18 highway and it crosses the Frierfjord, a fjord in Telemark county. The bridge connects the town of Brevik in Porsgrunn Municipality to the town of Stathelle in Bamble Municipality. When built, it replaced Brevik Bridge (Breviksbrua) as the primary route across the fjord.[1] [2]
The 608m (1,995feet) bridge uses cable stayed construction to provide clearance for vessels up to 50m (160feet) in height. The stay cables are arranged in 21 cable pairs with lengths from 84to. The bridge's span is 305m (1,001feet). It has two lanes, one per direction.
In 2021 the construction of a similar bridge started just west of the existing bridge. It will be opened in 2025, and then there will be four-lane motorway traffic with one direction per bridge.[3]
