Nevada Department of Transportation officials are warning some motorists that their vehicle may not make it through Cave Rock tunnel during construction.

Work started earlier this month to secure the rock so it doesn’t keep falling on the highway. The tunnel is be lengthened and other work done to solve the problem.

Traffic is being routed through the eastern tunnel. Vehicles wider than 8-feet, 6-inches and taller than 14-feet, 6 inches will not fit. Vehicles larger than this will have to find a route other than Highway 50.

The project is expected to be finished in the fall.
