Detailed Design of the Neckar Valley Bridge Horb, Germany
The Regierungspräsidium Karlsruhe has awarded the contract for the construction of the new Neckar Valley Bridge Horb to PORR Germany.
LAP is in charge of the detailed design of the viaduct on behalf of PORR. The design is to be carried out according to the BIM method. LAP has already been involved in the design of the bridge since 2008 (feasibility study). Between 2016 and 2021, LAP carried out the preliminary, basic and tender design on behalf of the Regierungspräsidium Karlsruhe.
The Bridge across the neckar Valley near Horb is part of the Horb bypass. It will create an additional crossing of the Neckar valley to the east of the town and thus provide comprehensive relief for the through road.
The Neckar valley bridge is a 6-span extradosed beam bridge that spans the up to 70 m deep Neckar valley incision with spans of 61 m - 115 m - 157.5 m - 157.5 m - 115 m - 61 m. The total length of the semi-integral structure is 667 m. The superstructure is designed as a haunched continuous girder.
Construction of the elevated bridge will start in 2023, with traffic opening planned for 2026.
