Interstate 70 off-ramp to close weekdays as Aurora project work on new interchange

The westbound Interstate 70 off-ramp to Colfax Avenue in Aurora will close for about two weeks starting Monday because of the city’s I-70 Picadilly Interchange Project.

The project will close the off-ramp Monday through Friday from 9 a.m. to 3 p.m. until Sept. 20. The ramp will be open Saturdays and Sundays, according to the news release.

To access Colfax Avenue during the closures, drivers can continue west on I-70 and exit to Tower Road, the release said.

The ramp is closing so crews can perform direct work in the I-70 median to build the project’s diverging diamond interchange, which will have advanced signaling systems and better lighting for drivers, pedestrians and bicyclists, according to the release.

Construction on the new interchange began last year and is expected to continue until late 2025.

The I-70 Picadilly Interchange Project is funded by the city, the Aerotropolis Regional Transportation Authority and a $25 million federal grant from the Federal Highway Administration, according to the city’s website.
