2020 Periodic Updates

(These updates provided by Coconino County cover the overall project, including the water and sewer upgrades)

September 4 - The FUTS reroutes at the north end of the project, near University Heights, have been removed and trail users are back on the original FUTS alignment. FUTS temporary reroutes at the south end (from Purple Sage Road into Fort Tuthill County Park) remain in place and trail users are temporarily rerouted onto Purple Sage Road. Please watch for vehicular traffic and follow detour signs.

Beginning Tuesday, Sept. 8, the project contractor will begin work in the Mt. Dell community and will be setting up traffic control and a digital message board now in preparation for that. Actual traffic control, flagman, and delineators will be set up next week once work begins. Please be alert and drive with caution in the area.  

August 14 - FUTS Trail users along the Sinclair Wash segment (west end) will continue to experience temporary trail reroutes near University Heights to Mt. Dell due to sewer construction. The reroutes began August 10 and will last approximately three weeks. Trail users should follow all detour signs and stay out of the construction zone for their own safety due to heavy equipment and water/wastewater line trenches. During the weekends, this portion of the FUTS trail is open with fencing and signage in place at the construction site.

Trail users will continue to experience temporary FUTS trail reroutes further south on this segment, where trail users are being rerouted onto new singletrack and on to Purple Sage Road, which is open to vehicular traffic. This reroute is expected to stay in place until October. Please use caution and be aware of traffic.

August 6 - FUTS Trail users along the Sinclair Wash segment (west end) will experience temporary trail reroutes near University Heights beginning August 10 for approximately three weeks. Trail users should follow all detour signs and stay out of the construction zone for their own safety due to heavy equipment and water/wastewater line trenches.

Trail users will continue to experience temporary FUTS trail reroutes further south on this segment, where trail users are being rerouted onto new singletrack and on to Purple Sage Road, which is open to vehicular traffic. Please use caution and be aware of traffic.

July 31 - Trail reroute update: The Soldiers Trail reroutes have been removed and trail users are back on the original trail alignment. The temporary reroutes for the FUTS Trail north of the park remain in place; please follow all detour signs and do not enter the construction area for your own safety.

July 24 - Attention Soldiers Trail users at Fort Tuthill County Park: The recent construction work with the water/wastewater line has required us to put in a reroute on portions of the Soldiers Trail in the park. Please follow all reroute signage and do not enter the construction area for your own safety. These are temporary reroutes, as are the FUTS reroutes north of the park, and we’ll be getting you all back on the original trails soon. Thanks for your patience. 

July 13 - This week, contractors for the Fort Tuthill Utility Improvement Project are installing water line in the north section of Fort Tuthill County Park and along the FUTS Trail in that area. Work is expected to take a couple of weeks. FUTS Trail users will experience reroutes in this area and will be rerouted onto Purple Sage Road and an internal ADOT road within the park. Please follow detour signs and be aware of traffic on Purple Sage Road.
