The Eads Bridge is a steel technology combined road and railway bridge over the Mississippi River at St. Louis, connecting St. Louis and East St. Louis, Illinois. Opened in 1874, it was one of the earliest long bridges built across the Mississippi, the world' first all steel construction, and built high enough so steamboats could travel under. As such, the St. Louis Landmark is listed on the U.S. National Register of Historic Places, as a U.S. National Historic Landmark. As of April 2014, it carries about 8,100 vehicles daily, down 3,000 since the new Stan Musial Veterans Memorial Bridge opened in February 2014.The bridge is named for its designer and builder, James B. Eads. When completed in 1874, the Eads Bridge was the longest arch bridge in the world, with an overall length of 6,442 feet (1,964 m). The ribbed steel arch spans were considered daring, as was the use of steel as a primary structural material: it was the first such use of true steel in a major bridge project. The cost of building the bridge was nearly ten million dollars.The Eads Bridge was also the first bridge to be built using cantilever support methods exclusively, and one of the first to make use of pneumatic caissons. The Eads Bridge caissons, still among the deepest ever sunk, were responsible for one of the first major outbreaks of "caisson disease" (also known as "the bends" or decompression sickness). Fifteen workers died, two other workers were permanently disabled, and 77 were severely afflicted.
The MacArthur Bridge over the Mississippi River between St. Louis, Missouri and East St. Louis, Illinois is a 647-foot (197 m) long truss bridge. Construction on the bridge was begun in 1909 by the city of St. Louis to break the Terminal Railroad Association of St. Louis's monopoly on the area's railroad traffic. Money ran out before the bridge approaches could be finished, however, and the bridge did not open until 1917, and then only to automobile traffic. Railroad traffic would not use the bridge's lower deck until 1928.The bridge was initially called the "St. Louis Municipal Bridge" and known popularly as the "Free Bridge." Tolls were added for auto traffic beginning in 1932. In 1942 the bridge was renamed for Douglas MacArthur.The MacArthur Bridge was one of several bridges in St. Louis which carried U.S. Highway 66 until the completion of the nearby Poplar Street Bridge. At one time U.S. Highway 460 crossed the bridge, terminating on the west side of the bridge. In 1981 the bridge was closed to vehicles because of pavement deterioration and the eastern ramp approaches were torn out. The bridge is now in use only by railroads. The disused vehicle deck has been removed.By 2007 only about 30% of the total deck reserved for automobile use had been removed. Most of the removed sections were on the East St. Louis side. The western ramp was relinquished to Ralston Purina and turned into a parking lot. In 2013 the TRRA began removing all of the auto deck over the river. By late 2014, the vehicle deck on the bridge proper had been removed, and work was progressing onto the western approach.
