Angers Bridge, also called the Basse-Chaîne Bridge, was a suspension bridge over the Maine River in Angers, France. It was designed by Joseph Chaley and Bordillon, and built between 1836 and 1839. The bridge collapsed on 16 April 1850, while a battalion of French soldiers was marching across it, killing over 200 of them.
The bridge spanned 102 m, with two wire cables carrying a deck 7.2 m wide. Its towers consisted of cast iron columns 5.47 m tall.
