More capacity for Olten region: Aare bridges/Aare footbridge

The Olten bridge over the Aare river is part of the Olten bypass road while the Aare footbridge is the new footpath and bike trail connection over the Aare and thus creates the link both to the city centre and districts to the south of the SBB line.

Olten Aare bridge: The Aare bridge is part of the Olten bypass road. The new bridge crosses the Aare river with no supports. The tunnel portal of the Hausmatt tunnel that follows is integrated into the bridge project and forms a static component of the bridge construction. The two pretensioned main beams simultaneously prevent falls from the side and serve as noise protection. They span the river with no supports over a distance of 88.5 metres. To reduce stress and deformation, the beams are suspended on pretensioned concrete sails and braced to the tunnel portal on the left bank of the Aare. The portal structure thus becomes a supporting component of the bridge.

Aare footbridge: The Aare footbridge is the new footpath and bike trail connection over the Aare: it is used for non-motorised traffic in the area of the Gäu train bridge from the various parts of Olten city on both sides of the rivers and is thus the connection both to the city centre and districts to the south of the SBB line. It has a total length of 88.35 metres and a usable width of 5 metres and thus provides more space for slow-moving traffic than the previous Aare crossing.
