Project Description

The Tullhus Bridge is a 1st prize winner in an invited architectural competition organized in 2008. This new bridge is located in Norrköping and takes pedestrians and cyclists from Strömsholmen to the north quay in the city centre. The bridge has been part of the urban planning already since the early 50’s, but it wasn’t until now, when the city begun building a new residential area around Strömsholmen, the plans were brought into effect. In 2008 the municipality invited Erik Andersson Architects to an architectural competition and the construction of the long awaited bridge, which will link the new area to the existing city centre, could begin in 2012 The 72 meter long bridge is constructed of steel and has an hourglass-shaped body tapering towards the center both in plan and section. The middle portion depth is 0.86 m. The bridge is painted in silver metallic and its shiny underside reflects the water in Motala Ström that has played a central role in the life of the city since the Middle Ages. A built-in hot-air system makes it possible to heat the bridge and keep it clear from snow in the winter. The first air-heated bridge in Sweden required a complicated construction process. It was prefabricated in one piece and, after welding and sandblasting, transported in one single piece 3 km through the streets of Norrköping before reaching the building site. The bridge connects two banks of distinctive character. On one side sits an old industrial dock, while a natural shoreline marks the other. The body consists of welded plates, which have been sandblasted and painted, while the walkway is draped by a layer of acrylate. The width of the walkway as well as the height of the beam increase towards the middle of the bridge. The beam height is 1.6 m at the supports and 0.86 m at the middle of the bridge. 
The bridge has vibration dampers to counteract vertical oscillations. The structure employs a welded hollow beam and 12mm thick plates covering the underside of the bridge. The handrails feature a built-in LED lighting system, illuminating the walkway and guiding pedestrians and cyclists over the snow-free bridge.
