Tower Bridge is a combined bascule and suspension bridge in London, England over the River Thames. It is close to the Tower of London, which gives it its name. Tower Bridge is sometimes mistakenly referred to as London Bridge, which is actually the next bridge upstream.
Construction started in 1886 and took eight years with five major contractors – Sir John Jackson (foundations), Baron Armstrong (hydraulics), William Webster, Sir H.H. Bartlett, and Sir William Arrol & Co. – and employed 432 construction workers. E W Crutwell was the resident engineer for the construction. The bridge was officially opened on 30 June 1894 by the Prince of Wales, the future King Edward VII, and his wife, Alexandra of Denmark.

Also known as the “haunted” bridge, Roseman is where two sheriff’s posses trapped a county jail escapee in 1892.

In Robert James Waller's novel The Bridges of Madison County and the movie of the same name, Roseman is the bridge Robert Kincaid seeks when he stops at Francesca Johnson's for directions; it is also where Francesca leaves her note inviting him to dinner.

The Anthony Wayne Bridge was named for General "Mad" Anthony Wayne, a military man with a ton of influence in the Maumee River valley (from Fort Wayne, IN downstream to Toledo, OH). The Anthony Wayne Bridge was built upstream of the former Cherry Street Bridge and opened to traffic in 1931. The $3 million suspension bridge is 3,215 feet long including approaches and raises 104 feet above the water at its midpoint.
The towers feature various lattice patterns, and some of the structural steel on them is itself latticed.
