Ralph L. Wadsworth Construction led the design-build team that widened 13 miles of I-15 southbound through the Salt Lake Valley, widened a segment of 7200 S. to three eastbound and westbound lanes, and reconfigured the I-15/I-215 interchange. Work included rehabilitation, widening, or narrowing of 24 bridges and building MSE walls in this tightly constrained corridor. The team met UDOT’s goal to reduce impacts to motorists by limiting lane closures to nighttime.
