Central Park Boulevard Interchange with I-70 Design-Build - Denver, CO

This signature $30 million interchange design and construction project for the City and County of Denver serves as a gateway for visitors entering the city from Denver International Airport, as well as providing an important new interstate access within the city limits.

Minimizing impacts to the traveling public was identified as a key project goal which led to a combination of Accelerated Bridge Construction (ABC) techniques and Construction Management/General Contractor (CM/GC) delivery. This was the first bridge design and construction utilizing this method for CDOT.

Braided ramp networks on both sides of I-70 provides direct access to and from both I-70 and I-270 with the Stapleton community, and local shopping.
