Pioneer Crossing Design-Build Submitted by Kiewit/Clyde JV
Pioneer Crossing is a design-build project that included six miles of new east-west connector from American Fork Main Street through Lehi to Redwood Road in Saratoga Springs, Utah.

Project elements included improvements at the Interstate 15 American Fork interchange, and a new 60-in. waterline for the Central Utah Water Conservancy District. Components included a 5- to 7-lane urban arterial with PCCP pavement, new bridges over the Jordan River and UPRR, new concrete box culverts at Dry Creek and Lehi Trail crossing, noise walls, retaining walls, aesthetics/landscaping, drainage, utility relocations, ATMS and traffic signal work.

An innovative diverging diamond interchange bridge at I-15 replaced the existing diamond interchange and included new ramps and I-15 widening. The DDI, which included twin, two-span prestressed concrete girder structures replacing an existing four-span structure over I-15, is an innovation in transportation design. Individual spans are up to 190 ft, 8 in. long and weigh approximately 2,300 tons each.
