I-70 Aerotropolis Parkway Interchange

About the Project

This is a local agency project for the Aerotropolis Regional Transportation Authority. The project consists of building a new interchange on I-70 east of E-470.

Work includes:

• Realigning the south portion of Colfax Avenue/I-70 Frontage Road
• Adding drainage ponds
• Building on and off ramps 
• Constructing a new bridge spanning I-70
• Constructing roundabouts on the north and south ends of the interchange that will eventually tie into future roadways

Project Benefits

• Provide much-needed access to the new Aurora Highlands community from Aurora and Adams County
• Improve connectivity to Denver International Airport and the adjacent Colorado Aerotropolis development

Work Schedule

• Working hours are 6 a.m. to 6 p.m., Monday to Friday
• Some overnight (7 p.m. to 5 a.m.) and weekend work also expected

Traffic Impacts

Motorists can expect the following impacts during the period of construction:

• Single overnight lane closures will occur in both directions of I-70 within the project limits from 6 p.m. to 6 a.m., Sunday to Thursday
• Single lane closures can be expected in both directions of I-70 within the project limits at anytime on Saturday and Sunday
• A full closure of I-70 will be in place to set girders for the new bridge structure later in the project, with detour routes posted
• Traffic shifts, lane closures and changing conditions will exist on the Colfax Avenue/I-70 Frontage Road during day and night work
• Signs and construction devices will be present to alert motorists to the work zone, impacts and other restrictions
• Construction schedules are weather dependent and subject to change
