The Aerotropolis Regional Transportation Authority and contract partner, Ames Construction, will begin construction of the I-70 Aerotropolis Parkway Interchange in Adams County in mid-August 2025. 

Part of ARTA’s planned regional transportation infrastructure improvements across the district, the purpose of the project is to provide much-needed access to developments from Aurora and Adams County, and to improve connectivity to Denver International Airport and the adjacent area served by the Aerotropolis Regional Transportation Authority.

Work includes realigning the south portion of East Colfax Avenue/I-70 Frontage Road and adding drainage ponds, building on and off ramps and a new bridge spanning I-70, and constructing roundabouts on the north and south ends of the interchange that will eventually tie into future roadways.
