Temporary Greenbelt Closure near Julia Davis Park for Geothermal Repairs 

Starting Monday, March 31 a short section of the Boise River Greenbelt under Capitol Boulevard will be closed while the city’s Public Works team repairs a geothermal pipe. The closure is expected to end the week of April 21. Greenbelt users are asked to follow all posted signs and use the detours at the Boise State Friendship Bridge and Ann Morrison Park Pedestrian Bridge.

Please note, detours are also in place at the 8th Street intersection adjacent to the Idaho Anne Frank Human Rights Memorial as mobility improvements are underway.

Warm Springs Grill + Golf Greenbelt Impacts

The Warm Springs Grill + Golf facility is under construction at Warm Springs Golf Course. The Boise River Greenbelt path along the north side of the Boise River that passes through the golf course is expected to remain open during construction. However, users should be aware of golf carts crossing the Greenbelt as well as heavy equipment working in the area.

Please slow down when traveling along the construction zone and pay attention to all posted signs, including stop signs at marked crossings, for your own safety. Temporary detours and re-routes near the construction site are expected as this project is built-out.

We will ensure the necessary alerts are provided and signage is posted to communicate temporary re-routes as the project progresses. This may also require cyclists to dismount and walk their bicycle through the area.

Thank you for your attention and understanding as we keep the safety of pedestrians, cyclists and golfers top of mind throughout the project.
