This presentation will discuss the challenges the C70 project team encountered and overcame in delivering the Colorado Department of Transportation’s (CDOT) largest design-build/P3 project to date. These challenges included coordination and reconstruction of the UPRR mainline crossing over I-70 into Denver, minimizing environmental impacts to the surrounding community during construction and viaduct demolition, coordination with local agencies and the community on the construction of a new 4-acre park over I-70, and construction of the lowered interstate through a Superfund site.

This presentation will disseminate best practices, lessons learned, and innovative techniques used by the Central 70 project team to deliver this critical infrastructure for the State of Colorado successfully.
