This fall, two employees of transportation consulting firm TranSystems Corp. will take the host of a new cable television show 90 feet up the Eads Bridge in St. Louis to explain how they identify, evaluate, and specify structural steel, masonry, and concrete repairs. The 6,442-foot span over the Mississippi River was the world's longest arch bridge when it was built in 1874. “We went over the safety regulations and he was ready to climb,” says Senior Bridge Engineer Jared Wigger of Don Wildman. According to its Web site, “Off Limits“ accesses “off-limits mega structures” to show “the true but forgotten narrative of how our cities came to be.” Visit www.travelchannel.com for air times.
