Trail Construction & Detours

Denver Parks and Recreation is constantly working to improve the over 100 miles of trails in the parks system. When doing improvements there may be temporary detours due to construction. We are committed to providing the safest detours available for the shortest amount of time necessary in order to minimize impacts to users.  For additional information related to current or planned detours, please refer to the project list below. (Under Construction, Available Soon)

Although we make every attempt to keep the public informed about the status of our multi-use trails, there are times when they must be closed immediately and may not be noted on this page.  Please be aware of unforeseen conditions due to weather or other unexpected events and be prepared to use alternate routes if necessary.

Project: Great Divide/River North Storm Sewer Outfall
Detour duration: April 20-May 22, 2015
Portion of trail closed: 38th - 31st St.
View detour map

Project Summary:
The closure of the South Platte River Trail is needed to accommodate the construction of the new storm sewer outfall from the Great Divide Brewing Company (which will provide drainage for both The Great Divide and the future River North Park site).  The project will need to remove a portion of the trail during construction so that the new outfall pipe and headwall can be built.  Once completed, the trail will be restored.

Project: 6th Ave. Bridge Reconstruction
Detour duration: January 29 – May 15
Portion of trail closed: 7th Ave. – Bayaud Ave.

The closure of the South Platte River Trail (7th Ave. – Bayaud Ave.) is needed to accommodate reconstruction of the US 6 Bridge as well as improvements to trail between Frog Hollow and Phil Milstein Parks. The concrete trail will be widened from 8 feet to 12 feet and a soft-surface running path will be added adjacent to the concrete trail.

Trail users traveling southbound should use the on-street detour of:
th Ave. > Bryant St. > 2nd Ave. > Tejon St. > Bayaud Ave.

Trail users traveling northbound should follow the same detour in reverse:
Bayaud Ave. > Tejon St. > 2
nd Ave. > Bryant St. > 7th Ave.

Project: Confluence Park/Shoemaker Plaza
Detour duration: late February 2015 - August 2016
Closure: Shoemaker plaza;
S. Platte Trail- 19th St. to Speer Blvd.

The first phase of Confluence Park’s master plan will begin in late February and includes the closure of Shoemaker plaza and surrounding portions of the S. Platte River Trail until August 2016. Shoemaker Plaza is located on the west side of the South Platte River near the REI store and was built in the 1970s. As part of the larger plaza reconstruction, its concrete ramps will be replaced by a 12 foot wide, fully accessible bicycle and pedestrian ramp that will meet today’s Americans with Disabilities Act (ADA) requirements. This ramp is a key connection to the South Platte River regional trail system and will provide better access to the plaza, which will be reconfigured to create more usable outdoor space for social activities and other events in Confluence Park. The cost of this project is approximately $4.2 million.

Project: Washington Park – Downing Street Irrigation
Detour Duration: June 1 - July 15, 2015
Portion of Trail Closed: Exposition Avenue entrance to E Kentucky Ave entrance.

View detour map

Project Summary: The closure of the running trail is needed to accommodate the installation of new irrigation laterals and mainlines between Downing Street and the restored Perennial Gardens.  The project will require trenching through the existing trail which necessitates closing this section of the trail for safety reasons.  The trail will be fully restored using the same crusher fines and reopened in mid July.  Running trail users can detour from the crusher-fines running path onto the shared pedestrian section of the Loop Road just north of the Parking Lot southwest of Smith Lake (see map), then continue on the Loop Road until the E Kentucky entrance where they can rejoin the crusher-fines running trail.
