It was originally known as the St. Louis Bridge, later renamed after its designer, the self-taught engineer James B. Eads. The first cornerstone of the Eads Bridge was laid in 1868 and When developing the design of the bridge, Eads faced a number construction was completed in 1874, with General William Tecumseh of challenges due to restrictions in place at the time, including that Sherman driving in the last spike to officially open the bridge on July 4, the bridge could not be made of wood, could not be a drawbridge 1874. The Eads Bridge was the largest bridge ever constructed up to or suspension bridge, and had to be tall and wide enough to that time, with three spans each more than 500 feet long. It required accommodate all types of river traffic. To address these challenges, Eads more than 5,500 tons of steel and wrought iron to complete. developed a design noteworthy for a number of construction firsts: Today, ownership of the bridge is shared by the City of St. Louis • The first bridge, and one of the first structures in the country of any and Bi-State Development. kind, to use steel as a primary construction component • The first bridge in the U.S. to employ pneumatic caissons • The first bridge built entirely using cantilever construction methods, which kept the river open for commerce • The first bridge in the U.S. to use hollow tubular chord members The rehabilitation work performed has extended the life of the Eads REHABILITATION Bridge for at least another 75 years. The project team also completely replaced the MetroLink structural The Eads Bridge Rehabilitation Project began in 2012, the first full-scale flooring system, ties and rails on the bridge, and replaced messenger rehabilitation of the bridge since its opening in 1874. and contact wires with new overhead conductor rail, making Metro one of the first transit systems in the nation to use this state-of-the-art In preparation for the project, a new rail interlocking was installed just technology to power MetroLink more efficiently and reliably. west of the East Riverfront MetroLink Station in 2011, which would allow both eastbound and westbound MetroLink trains to use the The Eads Bridge Rehabilitation Project was completed in 2016, and both same track on one side of the Eads Bridge, while crews could work on MetroLink tracks returned to service on June 13, 2016—the first time the other side.

The Bridge for the duration of the project. City of St. Louis, which co-owns the bridge with Bi-State Development, contributed a $4.8 million federal grant toward the project, During the rehabilitation of the Eads Bridge, crews installed more than and remaining costs are supported by local sales tax. 1,167,000 pounds of steel to replace struts, bracing and other support steel that dated back to the 1880s. As many as nine layers of paint, rust and corrosion were blasted off of the bridge down to the bare metal inside of an environmental containment system that protected the air, the river, the workers, and people traveling across the bridge from contaminants. To replace it, more than 7,500 gallons of a multilayer anti-corrosion coating were applied to the bridge. In total, crews made about 1,200 structural repairs to the bridge, as well as substantial reconstruction of the concrete that supports the road deck. CONTRACTOR K.
