The Cooper River Bridges were a pair of cantilever truss bridges that carried traffic over the Cooper River in Charleston, South Carolina, United States. The first bridge opened in 1929, a second one opened in 1966 to relieve traffic congestion. The Grace Memorial Bridge was designed and constructed by a private company known as Cooper River Bridge, Inc, and the Pearman Bridge was designed by HNTB Corporation and constructed by SCDOT. The bridges were replaced with the Arthur Ravenel Jr. Bridge in 2005.
