⭐ Core Definition: Nordhordland Bridge

The Nordhordland Bridge (Norwegian: Nordhordlandsbrua) is a combined cable-stayed and pontoon bridge which crosses Salhusfjorden between Klauvaneset (in Bergen Municipality) and the island of Flatøy (in Alver Municipality) in Vestland county, Norway. It is 1,614 meters (5,295 ft) long, of which the pontoon section is 1,246 meters (4,088 ft) long. The cable-stayed section consists of a single 99-meter (325 ft) tall H-pylon which has a length of 368 meters (1,207 ft) and a main span of 172 meters (564 ft). This allows for a clearance of 32 meters (105 ft).

The floating section is a steel box girder bridge with ten pontoons, which because of the fjord's depth are not laterally anchored. The roadway sits on an orthotropic deck. The pontoons and the cable-stayed bridge are built in concrete, with the main span being supported with 48 cables. The fjord end of the main span is supported by a 30-meter (98 ft) deep foundation, where the two bridges meet. From there and for 414 meters (1,358 ft), the roadwall has a 5.7 percent gradient on a viaduct anchored to the pontoon bridge.

👉 Nordhordland Bridge in the context of Flatøy

Flatøy is an island in Alver Municipality in Vestland county, Norway. The 2.2-square-kilometre (0.85 sq mi) island lies in the district of Nordhordland, just north of the city of Bergen. The main village on the island is Krossneset on the southern part of the island. The northern part of the island, on the southwest shore of Kvernafjord, is very sparsely inhabited. Historically, the island was one of the two main islands of the old Meland Municipality.

The island is strategically located at a major transportation crossroads. It lies between the Salhus neighborhood of Bergen Municipality (to the south), the island of Holsnøy (to the west), and the village of Knarvik to the east. The island is connected to these larger communities by three bridges: Nordhordland Bridge connects it to Salhus, the Krossnessundet Bridge connects it to Holsnøy, and the Hagelsund Bridge connects it to Knarvik. Since the only road connection from Bergen to Nordhordland is via the Nordhordland Bridge, Flatøy serves as the entry point to the whole Norhordland district.

Nordhordland Bridge in the context of Pontoon bridge

A pontoon bridge (or ponton bridge), also known as a floating bridge, is a bridge that uses floats or shallow-draft boats to support a continuous deck for pedestrian and vehicle travel. The buoyancy of the supports limits the maximum load that they can carry.

Most pontoon bridges are temporary and used in wartime and civil emergencies. There are permanent pontoon bridges in civilian use that can carry highway traffic; generally, the relatively high potential for collapse and sinking (e.g. due to waves and collisions) and high continuous maintenance costs makes pontoons unattractive for most civilian construction. Permanent floating bridges are useful for sheltered water crossings if it is not considered economically feasible to suspend a bridge from anchored piers (such as in deep water). Such bridges can require a section that is elevated or can be raised or removed to allow waterborne traffic to pass. Notable permanent pontoon bridges include the Hood Canal Bridge and the Nordhordland Bridge.

Nordhordland Bridge in the context of Åsane

Åsane is a borough of the city of Bergen in Vestland county, Norway. The borough makes up the northern part of the city, north of the city centre.

Åsane is connected to downtown Bergen by the E16/E39 highway. The E16 highway continues on through Åsane to the southeast to the neighboring borough of Arna. The E39 highway continues north through Åsane to the Nordhordland Bridge and then on to the northern municipalities in Vestland county. There are plans to shorten the E39 highway through Åsane, including the construction of two tunnels: Eikås Tunnel (start of construction 2010) and the Nyborg Tunnel (still in the planning stages). Most buses passing through Åsane stop at the centrally located Åsane Terminal.
