The Lewis and Clark Viaduct (previously the Intercity Viaduct and historically the Interstate Viaduct; also known as the 6th Street Viaduct or Woodsweather Bridge) are two nine span viaducts that cross the Kansas River in the United States. Designed by Waddell and Hedrick, the first viaduct, a four-lane, deck truss bridge, opened to the public on January 29, 1907, the second bridge, also of the deck truss design, opened to the public on November 12, 1962. It rises above the West Bottoms, and several sets of railroad tracks. The 1907 viaduct is notable for being 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 Interstate 70/U.S. Route 24/U.S. Route 40/U.S. Route 169 (I-70/US 24/US 40/US 169). The I-670 Viaduct serves as a complementary to the viaduct, it was built in 1990 to the south.
