The District of Columbia plans to replace a pedestrian bridge that collapsed June 23 after being struck by a truck. The 65-year-old steel-and-concrete structure, which spans a six-lane highway, was three inches lower than D.C.’s minimum clearance of 17.5 ft and was found to be in poor condition following a recent inspection. D.C. transportation officials said the bridge’s condition did not contribute to the collapse. The replacement bridge, which the District hopes to complete within three years, will cost approximately $25 million to build.
