Rebuilding the Merchants Bridge while Keeping Traffic Moving
Manage episode 339757708 series 30874
Replacing an active railroad bridge while limiting disruptions to both rail and river traffic presents significant challenges in design and construction staging. The 1889 Merchants Bridge at St. Louis – the oldest remaining rail bridge across the Mississippi River – needed to be upgraded to modern standards. The work involved removal and replacement of three truss spans, accomplished in separate time windows, and demanding the precise coordination of multiple contractors, as well as rail and waterways operations.
In this podcast we talk with Dan Sieve, Senior Project Manager for Walsh Construction, the company that led the effort, to learn how the work was done.
