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.
