New Orleans Landmark is Widened and Strengthened

This article describes the third phase of a deck-widening project for the Huey P. Long Bridge, which crosses the Mississippi River above New Orleans. The 71-year-old bridge, notorious for its narrow lanes, is the longest railroad bridge in the U.S. Currently the bridge carries two rail tracks and four lanes of traffic on U.S. 90. The project will widen the bridge 43 feet to allow three, 11-foot-wide lanes in each direction. The project includes beefing up the pier in order to add big trusses to cantilever the new lanes. The article describes in detail how the sides of the piers will be encased in up to 18 inches of concrete, and the use of a limpet cofferdam system. The bridge, first built in 1935, is expected to be completely renovated by late 2010.
