The Huey P. Long Bridge Widening was a four-phase project vital to the recovery of Greater New Orleans.
The widening added an additional travel lane, as well as inside and outside shoulders to each side of the bridge, providing a safer and more reliable crossing over the Mississippi River.
This phase of the project entailed the replacement of the east and west approach structures and construction of a three-lane deck, widening both sides of the existing bridge.
The westbound and eastbound approach work includes roadway, roadway structures, concrete slab span, precast, prestressed concrete girder and steel plate girder bridges, bridge deck, and related work. The work also includes installation of structural steel stringers and a cast-in-place deck onto the newly widened truss superstructure.
Major contract modifications included a change in bolsters and alternate barrier using newer design for the mainline bridge; defective BT-78 girders; rotator method credit claim; and additional traffic maintenance aggregate.
