The Travel Channel featured MetroLink, St. Louis Metro’s light rail system, in a recent episode of its series Off Limits. The show follows host Don Wildman as he takes viewers behind the scenes and inside U.S. locations and landmarks they would never be allowed to explore.

While the main focus of the program is the city’s historic Eads Bridge, co-owned by Metro and the city of St. Louis, it includes footage of Wildman on board MetroLink talking with Eric Fields, Metro senior project manager in engineering, and walking down the tracks toward the inner portions of the bridge.

Wildman, accompanied by a crew from Authentic Entertainment, rode MetroLink to the Arch-Laclede’s Landing Station and met with Fields, who shared the history of the Eads Bridge—which opened in 1874 and crosses the Mississippi River between St. Louis and East St. Louis, IL—and the role of the riverfront in the development of St. Louis. Wildman then put on a safety harness and climbed out on the bridge while dangling over the Mississippi River with a bridge inspector.
