Hochbrücke Wismar, Prestressed concrete road bridge in Wismar, Germany

Hochbrücke Wismar is a 398-metre prestressed concrete road bridge on Landesstraße 12, opened on 7 August 1970 and partly crossing the Mühlenteich. It was built to relieve the Rostocker Straße, then the only eastbound exit road, and cost 15.3 million GDR marks. Since 2012 it carries two lanes instead of four.

Built because Rostocker Straße, the only eastern exit road, had become a bottleneck, the bridge was inaugurated on 7 August 1970. The 398-metre structure cost 15.3 million GDR marks. Poor subsoil and resulting statics problems forced a complete overhaul in 2004 and 2005, which also changed traffic routing and footpaths.

The planned replacement bridge was to use the site of the Wismaria malt factory, built in the 1890s. After a new owner took over the ruin in late 2019 and the state heritage office confirmed its value as a monument, the demolition plans were dropped and new variants had to be examined.

The bridge undergoes regular inspections due to structural concerns and operates with certain lane limitations at present. Visitors using this route should be aware that traffic conditions may vary and peak times can bring congestion.

The preferred replacement route presented in April 2021 would run directly beside the old bridge, but it is contested: some residents and the AG Baukultur favour an underpass, and a 2022 competition sought solutions without a new high bridge. The old structure was rated 3.5 (insufficient) from 2015.
