Live the experience by Nicholson Construction: the Merchants Bridge Project in Saint Louis, Missouri
Merchants Bridge is a historic through-truss railroad bridge that crosses the Mississippi River north of St. Louis, Missouri. The bridge is the sixth busiest freight train crossing of the Mississippi River and hosts approximately 32 trains per day. The combination of the bridge’s location within the New Madrid fault system and the increased weight of rail traffic made the case for a repair project, which included expanding and encasing the existing piers, replacing the exiting truss spans and expanding and encasing the approach spans.
Nicholson was contracted by Walsh Construction to perform micropile installation as part of a rehabilitation project to upgrade the existing pier capacities. This required our team to work from land as well as on water. The work began in February 2020 and was completed in June 2021.
The project is on track for completion by early 2023.
