According to allcitycodes, the Daniel Boone Bridge is a truss and girder bridge in the United States, located in the state of Missouri. The bridge spans the Missouri River at Weldon Spring, a suburb of St. Louis. The bridge is part of Interstate 64.
The Daniel Boone Bridge are actually two parallel bridges with slightly different dimensions. The bridge is a total of 797 meters long with a main span of 156 meters, but the bridge to the east is wider than the bridge to the west. In addition, the bridge to the west is a truss bridge and to the east a girder bridge. The bridge has 4 lanes in both directions, but the bridge to the west has no hard shoulder. Interstate 64 runs across the bridge. The bridge is toll-free. It is the westernmost bridge over the Missouri River in the urban area of the St. Louis region.
The first bridge was built between 1932 and 1935, over which US 40 ran at the time. This was a steel truss bridge. This bridge originally had 4 lanes of traffic. With the growth of suburbs in St. Charles County, traffic increased and a desire arose to extend I-64 west from St. Louis to I-70 at Wentzville, via the Daniel Boone Bridge. To this end, a second bridge with 4 lanes was constructed in 1989. After that, the old bridge from 1935 was narrowed to 3 lanes for traffic safety.
Between January 2013 and November 2015, the bridge from 1935 was replaced by a new bridge. The new bridge was constructed upstream (west) of the existing bridges. The new bridge has 4 lanes, an emergency lane and a bicycle/pedestrian path, and was opened to traffic heading east on 29 June 2015. The bridge from 1989 was subsequently renovated, after which traffic heading west has been driving over this bridge since November 5, 2015, and the old bridge has been decommissioned. The old bridge from 1935 was subsequently demolished. The old bridge was blown up on February 18, 2016.
The bridge is named after Daniel Boone (1734-1820) an American explorer and icon of American history. He was one of the first Europeans to move west through the Appalachian Mountains. He spent the last years of his life in eastern Missouri, in what is now Defiance, about six miles west of the bridge.
In 2012, 98,000 vehicles crossed the bridge every day.

The Discovery Bridge is a truss bridge in the United States, located in the state of Missouri. The bridge spans the Missouri River in St. Charles, a suburb of St. Louis.
The Discovery Bridge are actually two identical parallel bridges. The bridge is 1,053 meters long and has a main span in the form of a truss bridge with a length of 190.5 meters. The bridges just don’t touch each other. Crossing the bridge is State Route 370, a bypass of St. Charles. The bridge is equipped with 2×3 lanes. The bridge is an alternative to the Blanchette Bridge of I-70 further south. The bridge is toll-free.
The Discovery Bridge was built at the same time as State Route 370 between 1990 and 1993. This new highway was intended to relieve Interstate 70 of local traffic. The bridge opened to traffic in 1992 or 1993. During the replacement of the Blanchette Bridge from I-70 in 2012-2013, the capacity of the Discovery Bridge was temporarily increased to 2×4 lanes by rearranging the lanes and closing the bike path.
In 2012, 59,000 vehicles drove over the six-lane bridge every day.
