The Intercity Viaduct (officially the Lewis and Clark Viaduct since 1969) is an automobile and pedestrian crossing of the Kansas River in the United States. Designed by Waddell and Redrick, this four lane, two level deck truss bridge was built in 1907. It rises above the West Bottoms, and several sets of railroad tracks. It was the first roadway bridge to connect Kansas City, Missouri with Kansas City, Kansas non-stop all the way across. It about one and a half miles long and carries Interstate 70 eastbound traffic, its sister bridge, the Lewis and Clark Viaduct built in 1962, carries westbound traffic.
The eastbound lanes were built as the Intercity Viaduct, carrying both east and west lanes, but renamed the Lewis and Clark Viaduct January 25, 1969, taking the name of its sister bridge that would now carry the westbound lanes, built in 1962 to the north.
Designed by the engineering firm, Waddell and Redrick in 1903, the viaduct followed a flood that same year that wiped out all but one of the 17 bridges that spawned the Kaw River.[1] Ground broke to mark the building of the bridge in 1905.[1]
