Mainbrücke Stockstadt, Prestressed concrete road bridge in Stockstadt am Main, Germany
Mainbrücke Stockstadt is a prestressed concrete bridge that carries the A3 Autobahn across the Main River. The structure features a prominent central span over the water while supporting six lanes of traffic across its length.
The bridge was built in the late 1950s to establish a direct autobahn connection between Frankfurt and Nuremberg. Later structural challenges led to substantial modifications that reshaped the original design.
The bridge design represents German engineering achievements of the 1950s, incorporating modern structural principles that influenced regional infrastructure development.
The bridge remains open for continuous traffic on the autobahn, allowing passage in both directions without interruption. Travelers should note that the roadway can be heavily congested during peak hours and standard autobahn safety rules apply.
The structure experienced a partial collapse in the 1980s, marking a turning point in German bridge construction methods. This incident prompted engineers to reconsider and improve their construction approaches.
