The $22 million Peoria Crossing Design-Build Project represents an unprecedented collaboration between the (Owners): City and County of Denver and the City of Aurora, and the additional: Regional Transportation District and Colorado Department of Transportation, to enhance the safety of the traveling public and operational efficiency of Peoria Street. Peoria Crossing is an important connection between Denver and Aurora that was hampered by the at-grade crossing of the Union Pacific railroad tracks. SEMA Construction, Inc. and Parsons Brinckerhoff, Inc. (Project Team) provided a design-build solution involving the construction of a grade-separated structure elevating Peoria Street over the UPRR yard and the future RTD East Rail Line.
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.
This $11.5 million award-winning project will reconstruct the existing interchange at Fillmore Street and I-25 in Colorado Springs, CO. The reconstructed interchange will be a diverging diamond interchange. Two new 2-span bridges will replace the existing structure. Each bridge is approximately 215 FT in length comprised of precast concrete U girders (U60). Additional work includes lengthening the SB off-ramp and the NB on-ramp.

“Thanks to a job well done with the Fillmore work over the past two weekends. I know this was a challenging period in many people’s lives as people put in long hours and time away from family. I recognize and see the hard work. It is a benefit to the traveling public as we will have a chance to finish early. I can already tell that traffic is running better.Take care, be safe and watch out for each other.” CDOT, Fillmore/I-25 Project Owner
Completed one year ahead of schedule, this $143 million design-build project was located on I-25 through Colorado Springs from Bijou Street to North Academy Blvd. Construction on I-25 widened the highway to three lanes along this 12-mile stretch. Scope included 12 miles of roadway with 18 bridge structures, seven major drainage structures, 250,000 SF of retaining wall, and work over the UPRR and BNSF railroads. SEMA was the only contractor to deliver every additional required element necessitated by the project owner.
This project involves the construction of a new two-lane vehicular bridge over Clear Creek which will connect Stanley Road to the Fall River Road/I-70 Exit 238 Interchange. Approximately 845 ft. of Stanley Road will be reconstructed to raise the roadway profile to the new bridge. Other work includes moment slabs, guardrail, roadway lighting, minor drainage improvements, and final striping and signing.
This $25 million project includes the reconstruction of Pecos Street between 56th Ave and SH 76, as well as construction of Osage Street from 59th Ave to 62nd Parkway. Work includes two cast-in-place concrete segmental bridges, four-lane roadway with a new bridge, MSE retaining walls and a two-lane roadway connecting 62nd Parkway with a new bridge and MSE walls. Project located within UPRR and BNSF ROW.
