Route 10 Tunnel Portal Road Rehabilitation
Zion National Park » Route 10 Tunnel Portal Road Rehabilitation » Document List
The National Park Service (NPS), in cooperation with the Federal Highways Administration – Central Federal Lands Highway Division, is proposing to complete road rehabilitation on Route 10 in the vicinity of the Zion-Mount Carmel tunnel in Zion National Park (Zion), Utah. The road work would primarily occur on the east side of the tunnel in a 0.25-mile segment beginning at the east tunnel entrance. Some road work would occur on the west side of the tunnel within several hundred feet of the tunnel entrance. Modifications on the east side of the tunnel would include slurry sealing the road surface and scaling rock slopes on both sides of the road; minor road widening to incorporate a safety median; reconfiguring two parking areas; creating a painted center median with rumble strips; relocating the crosswalk from parking area 1 to the Canyon Overlook Trail; constructing a sidewalk from parking area 2 to the Canyon Overlook Trail; eliminating three informal pullouts, one of which would be reconfigured as a slow vehicle passing lane; establishing erosion-control measures for the Pine Creek slot canyon access; and replacing and relocating the ranger kiosk.
The area outside of the west tunnel entrance would be modified to include a painted center median with rumble strips, and a new ranger kiosk. The improvements are needed to enhance overall traffic control and safety conditions for visitors and park rangers in this congested area and enhance resource protection.
The proposed project would provide a safer traffic control situation for park rangers and visitors, permit safer access to the Canyon Overlook Trail for visitors, reduce the potential for rockfalls onto waiting traffic and traffic control rangers on the east side of the tunnel, create better defined parking areas and better defined areas for park rangers to direct traffic, eliminate informal parking and associated resource damage and the problems associated with traffic control for visitors and vehicles in these informal parking areas, provide a slow vehicle passing lane; and minimize erosion on the Pine Creek slot canyon access.
