The Daniel Boone Bridge is the name for two bridges carrying Interstate 64, U.S. Route 40, U.S. Route 61 and the Avenue of the Saints across the Missouri River between St. Louis County and St. Charles County, Missouri. The older bridge, which carries westbound traffic, is a continuous truss bridge, while the newer bridge, which carries eastbound traffic, is a deck girder bridge.

Interstate 64 in Missouri
Interstate 64 (I-64) passes through the Greater St. Louis area in the US state of Missouri. The entire route is concurrent with U.S. Route 40 (US 40). Because the road was a main thoroughfare in the St. Louis area before the development of the Interstate Highway System, it is not uncommon for locals to refer to the stretch of highway as "Highway 40" rather than "I-64". On December 6, 2009, the portion of the highway running through the city of St. Louis was named the Jack Buck Memorial Highway in honor of the late sportscaster.
In 2008, I-64/US 40 was closed in this area for a complete reconstruction between 2008 and 2009. Shown is the Spoede Road overpass above I-64. This overpass was demolished in June 2008.
