I-10: Highland road to la 73 design build

Location: Baton Rouge, LA
Dates: January 2018 – August 2020

Huval and Associates led the design of all bridges for this project, consisting of 1 new twin bridge on mainline I-10, 1 widened twin span bridge on mainline I-10, and rehabilitation of an exisiting bridge on mainline I-10 in Baton Rouge.

The I-10 mainline bridge over Highland Rd. consisted of a full replacement of 2 existing twin structures utilizing a 3-span structure which included 2 presteressed girder spans and 1 steel plate girder span of 190′.

In order to maintain the high volume traffic on I-10 while reconstructing the bridge, the new bridge had to be constructed in 3 seperate phases.

The I-10 bridge over Bayou Manchac consisted of widening of 2 existing slab span structures supported by pile bents. The widening of the structures occured toward the centerline of the project so traffic could be maintained during construction.

LA 928 consisted of a bridge rehabilitation / girder replacement / span jacking of the existing 4 span prestressed girder structure. The rehabilitation consisted of repairing spalls, cracks, and cleaning. The girder replacement was necessary since a girder had been struck by an over height vehicle. The bridge also required the jacking of spans to facilitate the necessary vertical clearance of the new widened roadway section.
