322-metre-long Römershag viaduct in North Bavaria to be renewed by 2028 by a consortium made up of HABAU, Bickhardt Bau AG and MCE GmbH


April 2022 marks the go-ahead for the replacement construction of the Römershag viaduct in North Bavaria, Germany. In a comprehensive call for competition, the consortium consisting of HABAU Hoch- und Tiefbaugesellschaft m.b.H., earthworks and road construction partner Bickhardt Bau AG and steel engineering company MCE GmbH secured the contract commissioned by the federal government to renovate the viaduct built in 1946. The anticipated end of construction is the end of 2028.


The construction measures include the replacement construction of the Römershag viaduct as part of the A7 federal motorway between the junctions of Bad Brückenau/Volkers and Bad Brückenau/Wildflecken, in addition to all associated construction activities such as road construction, drainage, cable laying and noise protection and the construction of a new mobile silo.

“We are very happy to be able to bring our expertise in the construction and project management of complex bridges to this procedure. Together with HABAU, Bickhardt Bau AG and MCE, we are taking on the responsibility for this ambitious large bridge project, thus consolidating our position in the German market”, HABAU GROUP CEO Hubert Wetschnig is pleased to report.


Römershag viaduct: technical project scope of the major bridge construction


The existing Römershag viaduct will be replaced with a 322-metre-long, five-span steel composite bridge and will be implemented as a steel composite tubular truss with cast nodes in each direction of travel. Worthy of special mention is the fact that the cross-sectional geometry involves a triangle standing on its apex, which will be inserted lengthways in this position. Over the next few years, a total of 32 tonnes of steel and 14,500 cubic metres of concrete will be installed. In addition, 2,600 square metres of noise barriers will be put into place.
