Innovative Ideas Modernize 78-year-old Bridge

The Huey P. Long Bridge that spans the Mississippi River just north of New Orleans, Louisiana was in desperate need of renovation. The bridge was the largest steel railroad bridge in the United States at 22,995 feet when it opened in 1935 and it is still ranked among the longest today. The ability to move people and goods across the Mississippi River by train and vehicle opened commerce routes between ports and cities that were previously only serviced by ferries and bridges that were located over 200 miles away. This article discusses some of the innovative ideas that were used to modernize this aging bridge. In addressing capacity and safety issues for the bridge, a number of firsts were achieved, and these include: (1) an innovative method of lifting pre-constructed spans of widening trusses to minimize impact to vehicle, train and maritime traffic; (2) continuous community outreach and use of social media to keep the general public informed of progress, as well as potential inconveniences; (3) well-planned, integrated to project activities and interaction with the highway and railroad owners and the U.S. Coast Guard; and (4) the project was completed on budget and ahead of time.
