DENVER, CO

Awarded the 2013 ENR Best Project Award
SEMA partnered with The City & County of Denver Denver’s first design-build project. SEMA constructed a new interchange between Stapleton’s Central Park Blvd and I-70. This $30 million project included the design and construction of three bridges, including a six-lane bridge over I-70 and two ramp bridges. The interchange connects CPB and two major interstate highways: I-70 and I-270. More complex than a typical diamond-type interchange, a network of braided ramps was necessary along the north and south of I-70.
