This trail project will construct two miles of new Bonneville Shoreline Trail (BST) on the west flank of Grandeur Peak. This critical new trail section will connect the west end of the Pipeline Trail in Millcreek Canyon to the lower Quarry Trail accessed via the Grandeur Peak Trailhead. This will create a continuous BST segment from Millcreek Canyon to Parleys Canyon.

This non-motorized section of BST between Millcreek and Parleys Canyons has been in high demand and planned for over 20 years, but the project has not been feasible due to private property holdings across the west side of Grandeur Peak. The final two private parcels have now been purchased by Salt Lake County with funding from the Utah Office of Outdoor Recreation and this segment, which includes USFS property, is included in the 2005 Salt Lake County BST Master Plan. NEPA environmental assessments found no significant impact.

In 2021 a new Rattlesnake segment of BST was built from the Rattlesnake Trailhead in Millcreek Canyon to the Pipeline Trail by Trails Utah in cooperation with the USFS. Also in 2021, a new four mile segment of BST was built by Trails Utah going north from Parleys Canyon to Carrigan Canyon. Both of these new trail segments were immediately embraced and heavily used by the community. This newly proposed section of BST will join these two new trails creating almost 10 miles of continuous BST, including the paved trail and existing pedestrian bridges over I-80 at Parleys Canyon.

The completed trail will be a multi-use trail open to hikers, mountain bikers, and equestrians. Construction will begin in 2022.

This trail is on Salt Lake County Open Space and protected by Utah Open Lands Conservation Easement.
