New bridge deck on Interstate 80

Award of Excellence

Interstate 80, 4 Bridges in 37 Hours
Mountain Dell to Lambs Canyon
Salt Lake County, Utah

Since maintenance of traffic was driving project costs, the design-build team proposed replacement of the superstructure of all four I-80 bridges using self-propelled modular transporters. Innovative positioning of the temporary abutments at the lifting points eliminated additional stresses during the moving operation, greatly increasing the life of the bridges.
