It was certainly the largest oversize load that Interstate 15 in Utah County had ever seen or likely ever will see, as the Utah Dept. of Transportation�s I-15 CORE team moved the 354-ft, four-ton Sam White Bridge into place over the new freeway overnight on March 26.
The event near the town of American Fork on a misty, cold Saturday night was not only a milestone for UDOT’s accelerated bridge construction (ABC) program but also the largest bridge in the western hemisphere to be moved using self-propelled modular transporters (SPMTs).
