Faidherbe Bridge

As boats were insufficient to handle traffic between Saint-Louis island and the mainland, a bridge opened in 1865 and named after the colonial administrator Louis Faidherbe. With the introduction of rail traffic across the bridge, it too became insufficient and the current bigger one was opened in 1897, but it inherited the name of the older bridge. There's a myth that the bridge was designed by Gustave Eiffel – it's not, though his company indeed came second in the bidding process.
