Theodor Heuss Bridge, Mainz

The Theodor Heuss Bridge in Mainz is a stunning example of an arch bridge that stretches across the Rhine River, linking Mainz, the capital of Rhineland-Palatinate, with the Mainz-Kastel district of Wiesbaden in Hesse. This essential connection between the Bundesstraßes 40 and 455 has a main span of 102.94 meters and serves not only as a key roadway but also as a popular route for cyclists and joggers, offering spectacular views of the river and the Mainz skyline.

The area has a long history of bridges, beginning with a Roman bridge built in 27 AD. However, the first modern arch bridge was inaugurated on May 30, 1885, constructed using 3.5 million kilograms of wrought iron and costing 3.6 million gold marks. The original toll system, which helped recoup the construction costs, was eventually abolished in 1912 after nearly three decades.

The bridge's five steel arches, supported by sandstone pillars, span the river with a rhythm of 87-99-103-99-87 meters, creating an elegant and functional design. This was a project born from a nationwide competition, with the companies Philipp Holzmann and the Benckiser brothers winning the bid. Despite setbacks caused by flooding during construction, the bridge was completed in 1885 and became an instant landmark.

The Theodor Heuss Bridge underwent widening from 1931 to 1934 due to increasing traffic. Unfortunately, it was destroyed by German military engineers during World War II, on March 17, 1945, to prevent advancing Allied forces from using it. Rebuilt between 1948 and 1950, and partially reconstructed in the 1990s, it remains a vital link between the two states. Its historical significance and architectural elegance continue to make it a cherished landmark, symbolizing connection and resilience across the Rhine.
