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 is about 1.5 miles (2.4 km) long and carries Interstate 70 (I-70) eastbound traffic, while 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 on 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 spanned the Kaw River. Ground broke to mark the building of the bridge in 1905.
- 1907: Bridge opens to two lanes of toll traffic, with streetcar tracks.
- 1908: Bridge survives 1908 flood.
- 1911: Bank forecloses the bridge because the toll did not cover the bridge's cost.
- 1917: Bridge purchased by Kansas City, Kansas, and Kansas City, Missouri
- 1918: Ribbon cutting ceremony held to open bridge to free traffic under city control and ownership.
- 1930: Steel deck truss beams converted to a lower level, two lane automobile deck.
- 1936: Streetcar rails removed, and bridge opened to four lanes of traffic on upper level.
- 1951: Bridge survives 1951 Kansas City flood, the only bridge to remain open to traffic during the flood.
- 1962: The Lewis and Clark Viaduct is built to the north, old steel piers tubed off, and coated with concrete.
- 1969: Bridge renamed the Lewis and Clark Viaduct after its sister bridge.
- 1993: Bridge survives 1993 Kansas City flood.
- 1999-2000: Lower level of original (eastbound) bridge rehabilitated for pedestrian and bicycle access.
- 2007: Bridge turns 100 years of age, and several people gather from West Bottoms on the same day it opened in 1907, holding lights to the bridge in honor of its 100 years of service.
