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.
