During closures to Bannock Street:

Bicyclists heading into Downtown Denver are advised to avoid this segment of Bannock and travel Cherokee Street from 11th or 12th Avenue to cross W. Colfax Avenue and access the 15th Street protected bike lane in Downtown.

Bicyclists leaving Downtown Denver are advised to utilize Delaware Street to cross W. Colfax Avenue and access either 11th or 12th Avenues toward Bannock.

To access Downtown destinations from the west, bicyclists are advised to use the bike lanes along Galapagos Street – which becomes Welton Street north of W. Colfax Avenue. Alternatively, bicyclists travelling from the west may use 11th Avenue to Cherokee to arrive at Downtown destinations.

To access Downtown destinations from the east, bicyclists are advised to travel north to access on bike lanes along 16th Avenue or 11th Avenue.

Bicyclists travelling on the Cherry Creek bike path who want to access Downtown destinations are encouraged to use the bike exit ramp from the trail at 11th Ave and may use Cherokee to access downtown. 

During closures to Arapahoe Street:

Bicyclists are encouraged to use the shared right travel lane along 19th Street to access the buffered bike lane along Champa towards 15th Street. Bicyclists can use the protected bike lane along 15th Street to return to Arapahoe Street.

Annual Sediment Flushing

Tues. May 22 - Wed. May 23

The U.S. Army Corp of Engineers will conduct their annual flush to clear sediment trapped in the reservoir behind the Cherry Creek Dam. High flows are likely to flood bike paths and stream crossings along the Cherry Creek Trail between the reservoir and downtown. Travel time for water leaving the dam is about 6 hours to the stream gage at the Champa St. bridge, so high flows may continue until midnight on Wednesday, May 23.

Please do not attempt to cross the creek during this operation. Use crosswalks and sidewalks at street-level instead. 

  • The flushing operation involves high releases into Cherry Creek from each of the five main outlet gates at Cherry Creek Dam, located south of Interstate 225 in Aurora.

  • When the gates are opened, the high velocity of the water leaving the reservoir scours the area immediately upstream of the gates and transports sediment with the flow. The sediment flush is required to allow proper operation of the outlet gates.

  • The travel time from Cherry Creek Dam to the stream gage located near downtown Denver at the Champa Street Bridge is about 6 hours, so high flows can continue from morning until midnight Wednesday, May 23.

  • The high flows will cause potential flooding of bike paths and stream crossings particularly in lower areas of the creek.  In the interest of public safety, the public is urged not attempt to cross the stream during this operation.

  • Denver Park Rangers have been advising trail users of the release for the past few weeks.  Our trails team will be monitoring the trails throughout the day but will not begin clean-up until the following day when the water has receded.  Clean-up will begin at 5 a.m. on Thursday at 1st and Downing and entail plowing sand and mud, handwork, sweeping and then following with pressure washing to ensure the area is thoroughly cleaned.
