Melanbogenbrücke der L143
Melanbogenbrücke der L143, Road bridge in Troisdorf, Germany
The Melan arch bridge spans the Sieg River with a total length of 265 meters and consists of three sections including flood arches on both sides.
Built in 1929 using Josef Melan's patented construction method, the bridge replaced a ferry service and underwent reconstruction in 1949 after World War II damage.
This architectural monument represents German engineering craftsmanship from the early 20th century, connecting the industrial areas of Sankt Augustin and Troisdorf.
The bridge carries the L143 road between Menden and Friedrich-Wilhelms-Hütte, with vehicle weight restrictions limiting traffic to under 14 tons since 2006.
The bridge features temporary steel reinforcements called 'suspenders' installed in 2007 to maintain limited vehicle access despite structural deficiencies.
