Central Park Boulevard & I-70 Interchange Design-Build

SEMA partnered with The City & County of Denver on Denver’s first design-build project. SEMA constructed a new interchange between Stapleton’s Central Park Blvd and I-70.  The $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. The project was awarded the 2013 ENR Best Project Award in Highways/Bridges.
