Road-and-Rail Bridge Over Mississippi Gets a Physical
A joint venture participating in a massive steel-bridge-widening project in New Orleans is establishing a stress baseline for the structure before it is loaded with new steel by installing an 827-sensor monitoring array from end to end.
CTL Group, Skokie, Ill., is installing the sensors on the Huey P. Long Bridge to monitor it for changes during the $489-million third-phase superstructure-erection portion of the $1-billion project. Monitoring is a stipulation of the contract, says Steve Underwood, project manager for contractor MTI, a joint venture of Massman Construction Co., Kansas City; Traylor Bros. Inc., Evansville, Ind., and IHI Inc., New York City.
