The bridge opened on November 1, 1957, [10] connecting two peninsulas linked for decades by ferries. At the time, the bridge was formally dedicated as the "world's longest suspension bridge between anchorages", allowing a superlative comparison to the Golden Gate Bridge, which has a longer center span between towers, and the San Francisco–Oakland Bay Bridge, which has an anchorage in the middle.
The bridge was also listed on the National Register of Historic Places on May 3, 1977. [8] [9] In 1990, the National Railway Historical Society placed a historical plaque on the structure noting its size as the world's largest concrete bridge, completing the Summit cut-off project for the Delaware, Lackawanna and Western Railroad.
The bridge is the largest double-swing-span bridge in the United States, and second largest in the world. [1] [2] The toll bridge was named for George P. Coleman, who from 1913 to 1922 was the head of the Virginia Department of Highways and Transportation, predecessor to the Virginia Department of Transportation (VDOT).
The bridge has a central span of 4,260 feet (1.30 km; 0.81 mi). It was the longest suspension bridge in the world until it was surpassed by the Humber Bridge in the UK in 1981. The bridge has the 18th-longest main span in the world, as well as the longest in the Americas.
At 7,869 feet (1.490 mi; 2.398 km) in length (floating portion 6,521 feet (1.235 mi; 1.988 km)), it is the longest floating bridge in the world located in a saltwater tidal basin, and the third longest floating bridge overall. [3] It opened in 1961 and was the second concrete floating bridge constructed in Washington.
