Dare to look up at the Maintalbrücke Veitshöchheim. This impressive railway bridge gracefully spans the Main valley near Würzburg. It carries high-speed trains on the Hannover-Würzburg line.
The Maintalbrücke Veitshöchheim stretches 1280 meters. It stands 30 meters high. The bridge crosses the Main River at kilometer 244.86. It also crosses the Main-Spessart Railway and the B27 highway.
Imagine the challenges faced during its construction. The Maintalbrücke Veitshöchheim’s planning began in the 1970s. Many route options were considered due to Würzburg’s dense development.
Initially, there were citizen protests against the bridge. People worried about its impact on the landscape. They feared it would spoil the view from the Veitshöchheim Hofgarten. The bridge height was reduced from 50 meters to 29 meters because of these concerns. The original steel arch design was changed to a flatter bridge for aesthetic reasons.
The construction of the Maintalbrücke Veitshöchheim faced other hurdles. There were debates about where to deposit excess soil from the construction. A tunnel was proposed as an alternative. However, the railway company rejected it. The tunnel would have been too expensive.
Construction of the Maintalbrücke Veitshöchheim finally began in 1985. It took 31 months to complete. The costs amounted to approximately 40 million DM. The bridge’s arch over the Main was finished in December 1985.
The Maintalbrücke Veitshöchheim features a prestressed concrete beam superstructure. The longest span measures 162 meters. The bridge has a distinctive polygonal arch made of reinforced concrete.
The superstructure was built using the incremental launching method. This involved pushing sections of the bridge into place from one side. In 1986, this method set a world record here. The Maintalbrücke Veitshöchheim became the longest bridge ever built using this technique.
During construction, liquid nitrogen cooled the concrete to increase its final strength. Temporary cable-stays and counterweights balanced the load. They addressed the asymmetry caused by the superstructure’s weight.
Today, the Maintalbrücke Veitshöchheim stands as a testament to engineering and perseverance. It allows trains to travel at speeds of up to 250 km/h. The bridge connects regions and facilitates travel. As trains thunder across the Maintalbrücke Veitshöchheim, remember the debates, innovations, and dedication that made it possible.
