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 Hedrick, this four lane, two level deck truss bridge opened to the public on January 29, 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 is about 1.5 miles (2.4 km) long and carries eastbound traffic for Interstate 70 (I-70)/U.S. Route 24 (US 24)/US 40/US 169, while its sister bridge, the Lewis and Clark Viaduct, built in 1962, carries westbound traffic.
