Melanbogenbrücke der L143, Road bridge in Troisdorf, Germany
The Melanbogenbrücke der L143 is a road crossing over the Sieg River between Troisdorf and Sankt Augustin with a total length of about 265 meters and three sections including flood outlets on both sides. The arch is the most striking feature that gave the structure its name and sets it clearly apart from other bridges.
The structure was built in 1929 using a patented method developed by Josef Melan and replaced a ferry service at that time. After damage during the Second World War, the bridge was rebuilt and returned to service in 1949.
The bridge links two industrial towns and shows how vital this crossing was for the region's development. It stands as a reminder of when such structures formed the backbone of local economic life.
The route carries the L143 road between Menden and Friedrich-Wilhelms-Hütte but has had a weight limit for vehicles of under 14 tons since 2006. Visitors should note that the crossing is therefore only open to light vehicles and pedestrians.
The structure was fitted with temporary steel reinforcements in 2007 to allow limited use despite structural deficiencies. These supports are clearly visible and show how long engineering skill can keep an old structure standing.
