Coal Creek Trail Closure June 2014 - September 2015

The Coal Creek Trail is closed between Dillon Road and McCaslin Boulevard through fall 2015, while crews construct a new concrete box culvert. Once the culvert is complete, the existing trail will be reestablished through the western portion of the culvert and reopened to the public. The detour utilizing Dillon Road, 88th Street, South Rock Creek Parkway, and McCaslin Boulevard will keep bicyclists safely outside of the construction zone. The detour can be found here and will be in place and signed appropriately.

Project News for the Week of July 26, 2015

Toll collection will begin on Wednesday, July 22. To use the US 36 Express Lanes for free, you’ll need to create an ExpressToll account and get a Switchable HOV pass to carpool with two or more people in your vehicle (three or more by no later than 2017). If you have questions regarding paying tolls, opening an ExpressToll account, obtaining a pass or any other ExpressToll topics, please visit

Expect detours and finish work for final construction on the Phase 1 bikeway.  Watch for detour signage or flaggers where work is ongoing. The bikeway is now open from 88th Street to Turnpike Drive. Bicyclists will need to use roadway options and existing bike trails where the bikeway ends. The final section on the east end of the project at the Westminster Hills Park is scheduled to open to the public in early August.  Also in August, the Sheridan connection near the old Westminster Mall is scheduled for completion. Additional signage is being installed during this final stage. We appreciate your patience as we work to complete the bikeway.
