CDOT I-70 Twin Tunnels Expansion
JV Project (Kraemer North America & Obayashi Corp.)
Kraemer led the I-70 Twin Tunnels Expansion Program CMGC, which included the EB and WB tunnel widening projects, as the lead JV partner with Obayashi. Kraemer/Obayashi JV widened the EB bore to 53 feet and widened 3.5 miles of I-70 through challenging and environmentally sensitive terrain and an active waterway, ahead of schedule and under final contract budget. Kraemer/Obayashi JV worked with CDOT, the designer, and numerous active and engaged stakeholders to expedite the WB bore preconstruction phase. The WB project was completed on time under an aggressive schedule.
