Kolbäcksbron ( German Kolbäcksbrücke ) is a 530 m long one-hip cable - stayed bridge in the Swedish city of Umeå . Together with the Lillå Bridge, it forms the fourth road link over the Ume älv , which crosses the main roads E4 and E12 and is part of the main ring road around the city, which is due to be completed in 2017 [obsolete] .
Kolbäcksbron leads the streets from the eastern part of the city over the larger arm of the Ume älv, the Storån, to the island of Ön . The Lillå Bridge crosses the smaller arm of the river, Lillån, which lies between the island and the western part of the city.
Kolbäcksbron was designed by Inger Berglund. Construction by the Swedish company Peab began in 1998. There were several delays during construction . The pipes for anchoring the cables had to be cut off and re-welded because they were initially misaligned; furthermore, a girder failed during the concreting work due to a construction error. The opening took place eleven months late on September 5, 2001, which cost the construction company a contractual penalty of around SEK 10 million. The total construction cost was 120 million Swedish kronor.
The 20 m wide steel deck is supported by an asymmetrically placed pylon . The pylon, designed as a square frame, carries the roadway with 24 support cables arranged in a fan shape. The roadway has two north-facing lanes, one south-facing lane and a wide pedestrian and cycle path.
