Uddevalla Bridge
Template:Use dmy dates Template:Infobox Bridge
The Uddevalla Bridge (Template:Langx) is a cable-stayed bridge crossing Sunninge sound near Uddevalla in the province of Bohuslän on the west coast of Sweden. The bridge was constructed as part of the rerouting of the European route E6 outside Uddevalla, which reduced traffic congestion in the city and shortened traveling distance by Script error: No such module "convert"..
Dimensions
The total length is Script error: No such module "convert"., with a main span of Script error: No such module "convert"., there are a number of small approach spans at each end, and the two cable stayed side spans are Script error: No such module "convert". each. It is Script error: No such module "convert". wide, the clearance below the bridge is Script error: No such module "convert"., and the two pylons are Script error: No such module "convert". high. The cables are organised in a semi-fan arrangement.[1][2]
The bridge was constructed in 1996–2000 and was opened for traffic on 20Script error: No such module "String".May 2000.[1]
Construction notes
Structural engineering for the bridge was carried out by Johs Holt AS, and Skanska Teknik AB. Skanska also served as general contractor, with subcontractors Alpin Technik und Ingenieurservice GmbH (general), VSL International (cables), Mageba (bearings), and PERI GmbH (formwork and scaffolding).[1]
The cables are steel and the deck is composite steel-reinforced concrete, while the pylons are reinforced concrete.[1] About Script error: No such module "convert". of structural steel and Script error: No such module "convert". of concrete were used. The bridge and the connecting Sunningeleden cost of SEK 900 M (US$111 M) in 2000 currency values. [3] 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 Script error: No such module "convert". longer.[3] 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]
