what is the length of the ravenel bridge
Arthur Ravenel Jr. Bridge The Arthur Ravenel Jr. Bridge is a cable-stayed bridge over the Cooper River in South Carolina, USA, connecting downtown Charleston to Mount Pleasant. The eight lane bridge satisfied the capacity of U.S. Route 17 when it opened in 2005 to replace two obsolete cantilever truss bridges. The bridge has a main span of 1,546 feet (471 m), the third longest among cable-stayed bridges in the Western Hemisphere. It was built using the design-build method and was designed by Parsons Brinckerhoff.
Thames Tunnel The Thames Tunnel is an underwater tunnel, built beneath the River Thames in London, connecting Rotherhithe and Wapping. It measures 35 feet (11 m) wide by 20 feet (6 m) high and is 1,300 feet (396 m) long, running at a depth of 75 feet (23 m) below the river surface measured at high tide. It was the first tunnel known to have been constructed successfully underneath a navigable river[1] and was built between 1825 and 1843 using Marc Isambard Brunel's and Thomas Cochrane's newly invented tunnelling shield technology, by Brunel and his son Isambard Kingdom Brunel.
