Discovery Bridge

Discovery Bridge is a road bridge spanning the Missouri River in the St. Louis region, connecting St. Louis County to St. Charles County. It features six traffic lanes and includes a separated pathway for pedestrians and cyclists along its northeast side.

Construction took place between 1989 and 1992, establishing a major crossing over the Missouri River for the St. Louis region. This project represented a significant infrastructure development connecting two counties.

The bridge structure includes a dedicated path on the northeast side that connects travelers to the Katy Trail, a long-distance recreational path below.

This bridge handles heavy traffic and is accessible for pedestrians and cyclists year-round. Drivers and travelers crossing during peak hours should be prepared for busy conditions.

The main steel trusses were built 500 feet downstream on temporary supports before being moved to their final position. This construction method allowed workers to assemble the structure away from the active river.
