Traffic redevelopment Aarwangen-Langenthal North
All traffic between the motorway junction Niederbipp and the area of Langenthal leads today directly through the town of Aarwangen. The narrow roads are being used by pedestrians, bicycles, cars, lorries and the Langenthal-Solothurn railway alike. The traffic in Aarwangen has reached a level that severely restricts and strains both the residents and the road users. Forecasts predict a further increase in traffic until 2030, which will aggravate the problematic traffic situation additionally.
A two-lane, 3.6km long bypass road will be constructed for the heavy and transit traffic. This road crosses the river Aare in a 470 meter long bridge and passes underneath a forest in a 500 meter long tunnel.
In Aarwangen, north of the town center, bicycle measures are planned on both sides. In the center, the railway systems are to be directed in a double track on the road and a cycle lane will be marked. South of the center, the separately running railways will be renewed and secured.
