This design-build project featured a reconstruction of I-15 through Lehi from Main Street to SR-92 with a new one-way frontage road system in the area around Thanksgiving Point. The $450 million-dollar project with construction from 2018 to 2020 included two new lanes in each direction from Lehi Main Street to SR-92 (Timpanogos Highway). The work also included one new bridge and 13 bridge replacements. In addition to preliminary geotechnical investigations, RB&G provided geotechnical design reviews, construction-phase program management support, and teamed with the Utah Department of Transportation and HNTB in developing geotechnical RFP requirements. RB&G also provided Owner Verification Testing (OVT), construction engineering, and program management during construction.
