Gilman Tunnels to close for stabilization project

JEMEZ VALLEY — The Gilman Tunnels closed Monday for a rock stabilization project, with the closure extending to Dec. 1.

The Gilman Tunnels will be closed to all traffic, including mortorized, non-motorized and foot traffic.

“The Jemez Ranger District experienced a storm event in 2022 that caused considerable rock fall at the Gilman Tunnels. At that time, we identified the need to schedule periodic maintenance to mitigate rockfall hazards and ensure this popular destination can be enjoyed by future generations,” said Jemez District Ranger Jeremy Golston in a release.

The project includes removing immediate rock fall danger and stabilizing the rock cliffs surrounding the tunnels.

“A contractor will first identify and remove loose and unstable rock using a combination of hand tools and mechanical equipment. Then polyurethane resin is injected into each fracture to secure the cliff walls and tunnel portals, and finally rock bolts are installed to increase stability,” the release says. A similar project was completed in 2017.

It also says the resin will not be visible when the project is complete, “ensuring this historic landmark will maintain its beauty while providing safe access for all locals and visitors.”
