Denver’s Department of Transportation and Infrastructure (DOTI) announced two significant closures on busy streets that may cause commute changes. Alternate routes for the two areas are advised.

A “travel and safety improvement project” will shut down the ramp to southbound Interstate 25 on Broadway from Oct. 9 to 14, according to a press release from DOTI.

Drivers heading south on Broadway can reach southbound I-25 by taking the Alameda Avenue. Drivers heading northbound on Broadway can reach I-25 south by heading west on Mississippi Avenue and then north on Santa Fe Drive. Signs for the detour will be posted in the area.

The improvement project looks to add a new elevated on ramp, a new entrance to the RTD Park-n-Ride on Bannock Street and a new bikeway on Broadway to reach the RTD station.
