Ashton-Tetonia Trail Paving Project Update:

🚧 Trail Closure Notice 🚧

Exciting improvements are coming to the trail! 🎉

Starting April 1, 2026, the trail will be closed from the Ashton trailhead (N 3600 E in Marysville) to the Fall River Trestle as we begin paving this section. This closure will remain in place until further notice while crews work to make the trail smoother and more enjoyable for everyone.

We kindly ask that you respect all closure signs and traffic control devices and give our crews the space they need to work safely.

👉 Looking to hit the trail? The next available access point will be the Grainville parking lot.

Be sure to follow our page for the latest updates as the project progresses. We appreciate your patience and can’t wait for you to enjoy the finished product! 🌲🚴‍♀️✨

  • We’re excited to share progress on the Ashton-Tetonia Trail Paving Project! This multi-phase project will make the trail more accessible, enjoyable, and sustainable for years to come. Here’s the updated plan:
  • Paving 5.5 miles of trail, including:
  • Marysville to Fall River Trestle
  • Judkins Parking Lot toward Bitch Creek Trestle
  • Tetonia Parking Lot to Highway 33
  • Paving 5 parking areas for improved access
  • Installing 14 upgraded gates
  • Adding new trail signage for easier navigation

 

Thank you for your patience and support as we work together to enhance this treasured trail for our community and visitors alike.

Special Projects

Ashton-Tetonia Trail Paving Project The Idaho Department of Parks and Recreation plans to pave the Ashton-Tetonia Trail, Some work will begin this fall, with the majority scheduled for next year. Seeking to attract more users and to decrease the annual maintenance of the trail, the department secured federal funding to pay for the $3 million project. Based on the experience with the Coeur d’Alene Parkway and the Trail of the Coeur d’Alenes in North Idaho, the department expects the paving will be beneficial to the area’s economy. Project Details
  • Construction:

-3.56 miles from Ashton to Falls River Trestle

-0.92 miles from Judkins Parking Lot toward Bitch Creek Trestle

-0.94 miles from Tetonia Parking Lot to Highway 33

-Paving 5 parking areas for improved access

-Installing 14 upgraded gates

-Adding new trail signage for easier navigation

  • Length: Paving 5.5 miles of trail
  • Width: 8-10 feet
  • Thickness: 3 inches of asphalt over a 9 inch base layer of compacted material.
Funding comes from an EDA federal grant, which is designed for economic development. An economic impact study showed that the Coeur d’Alene Parkway and Trail of the Coeur d’Alenes contribute $1.4 million and $1 million, respectively, each year to the local economy. The benefits of a paved trail include a smooth surface for cyclists, parents with baby strollers, and for those with wheelchairs or other adaptive equipment. Asphalt will last many years with relatively low maintenance, alleviating the need to weeding, grading and other maintenance, which experience has shown to be a challenge.
