SANTA FE — Beginning Monday Oct. 14 and extending to Dec. 1, the popular Gilman Tunnels will be closed to all traffic, including motorized, non-motorized, and foot traffic to conduct a rock stabilization project.

“The Jemez Ranger District experienced a storm event in 2022 that caused considerable rock fall at the Gilman Tunnels,” Jemez District Ranger Jeremy Golston said. “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.”

The Gilman Tunnels and Forest Road 376 Slope Stabilization project involves removing the immediate rock fall danger as well as 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 injected resin will not be visible after project completion; ensuring this historic landmark will maintain its beauty while providing safe access for all locals and visitors. Similar stabilization work was last completed in 2017.

For more information on this project, call the Jemez District Office at 575.829.3535 or visit the offcie at at 51 Woodsy Lane in Jemez Springs.
