The **Uddevalla Bridge** (Swedish: *Uddevallabron*) is a [cable-stayed bridge](/source/Cable-stayed_bridge) crossing [Sunninge](/source/Sunninge) [sound](/source/Sound_(geography)) near [Uddevalla](/source/Uddevalla) in the province of [Bohuslän](/source/Bohusl%C3%A4n) on the west coast of Sweden. The bridge was constructed as part of the rerouting of the [European route E6](/source/European_route_E6) outside Uddevalla, which reduced traffic congestion in the city and shortened traveling distance by 12.8 km (8.0 mi).

## Dimensions

The total length is 1,712 m (5,617 ft), with a main span of 414 m (1,358 ft), there are a number of small approach spans at each end, and the two cable stayed side spans are 179 m (587 ft) each. It is 23.3 m (76 ft) wide, the clearance below the bridge is 51 m (167 ft), and the two [pylons](/source/Tower#Transportation_support) are 149 m (489 ft) high. The cables are organised in a semi-fan arrangement.[2][3]

The bridge was constructed in 1996–2000 and was opened for traffic on 20 May 2000.[2]

## Construction notes

Structural engineering for the bridge was carried out by [Johs Holt AS](/source/Johannes_Holt), and [Skanska Teknik AB](/source/Skanska). Skanska also served as general contractor, with subcontractors Alpin Technik und Ingenieurservice GmbH (general), VSL International (cables), Mageba (bearings), and [PERI GmbH](/source/PERI) (formwork and scaffolding).[2]

The cables are steel and the deck is composite steel-reinforced concrete, while the pylons are reinforced concrete.[2] About 9,000 t (20,000,000 lb) of structural steel and 35,000 m3 (1,200,000 cu ft) of concrete were used. The bridge and the connecting *Sunningeleden* cost of [SEK](/source/Swedish_krona) 900 M (US$111 M) in 2000 currency values. [1] There is a problem with ice sticking to the cables in the winter, which can fall onto cars. The bridge has to be closed a few times per year for this reason. The alternative road is 12.8 km (8.0 mi) longer.[1] Civil engineers have tested pulse electro-thermal de-icing - a way to use a burst of electricity to remove ice caked on walls or windows. For surfaces coated with a special film, the jolt gets rid of ice in less than a second, far less time than it takes to hack at it with an ice scraper.[4]
