John P. Grace Memorial Bridge : ウィキペディア英語版 | John P. Grace Memorial Bridge :''This article is about the original bridge which was demolished. For the bridge that was demolished along with it, see Silas N. Pearman Bridge. For the current bridge, see Arthur Ravenel Jr. Bridge.'' The John P. Grace Memorial Bridge, or the Cooper River Bridge as it was familiarly known, was a cantilever bridge that crossed the Cooper River in Charleston, South Carolina. It opened on August 8, 1929 and was built by the Cooper River Bridge Company. Shortridge Hardesty of Waddell & Hardesty, New York designed the bridge.〔(Hardesty & Hanover timeline, 1887-1938 ), accessed April 26, 2007〕 The Silas N. Pearman Bridge was opened beside it in 1966 to relieve traffic. They were both replaced by the Arthur Ravenel, Jr. Bridge in 2005. ==History== The ribbon was cut on August 8, 1929, at 1:12 p.m. by Col. James Armstrong, and between 30,000 and 50,000 people crossed the bridge during its first day. The bridge was owned by Cooper River Bridge, Inc., a private company. President of the company was John P. Grace, former mayor of Charleston. The bridge was built by a consortium of four engineering and construction firms. Construction lasted seventeen months, and the final cost of the bridge was six million dollars, to be financed by a 50-cent toll. The bridge had two lanes. In 1946 the state bought the bridge from Cooper River Bridge, Inc. and the 50-cent toll was removed. Unfortunately the same year a freighter rammed the bridge ripping down a section of it. Widening occurred in 1959 for a breakdown lane. Construction on the parallel Silas N. Pearman Bridge - intended to alleviate load limits on the Grace bridge - was completed in 1966. In 1979, a 3rd lane was added to the Grace bridge at the Charleston approach. By 1979, the bridge became functionally obsolete and there were many plans to replace the bridge, but not enough money.
