New A73 underpass for fast cycle traffic

Two variants were put to the vote, which can be realized in the course of the construction of the Stadt-Umland-Bahn (StUB): a solution with a two-sided footpath and cycle path and the smaller and significantly cheaper variant with a one-sided footpath and cycle path. The Zweckverband Stadt-Umland-Bahn (StUB), which is planning the route and the underpass structure, needs the decision at this point in time in order to coordinate further preliminary planning with the federal government's Autobahn GmbH and to draw up a corresponding planning agreement in good time, as the new underpass to be built will become the property and maintenance responsibility of the federal government's Autobahn GmbH after completion.

In future, the underpass under the freeway will play a central role in connecting the inner city and the Regnitzstadt to the Wiesengrund and the western districts as well as in the city's cycle path network. Cycle traffic will be routed without crossings on an important and extensive main axis.

The current technical data for the structure are as follows: The underpass is planned with a width of approx. 16.10 meters. The streetcar tracks are located in the northern section of the underpass with a width of 8.10 meters and a clearance height of 4.50 meters. Shared use of the tracks for bus services and emergency vehicles from the police, fire department and rescue services has been taken into account. The areas for cycling and pedestrian traffic are to be located to the south of the StUB route. These include the high-speed cycle link and a footpath with a combined width of 7.50 meters and a clearance height of 4.00 meters.
An initial estimate puts the costs for the city at between 6.5 and 7.5 million euros for the additional cycle and pedestrian undercrossing.
