Just looked at the NVDOT traffic cameras and there are big tractor trailer rigs going through it.

I do not know the exact height but I am at 11'2" and did not even think twice about passing underneath.

I’m 12’2. Concur with others... I can’t imagine anyone having issues. Plenty of clearance. It appears that commercial traffic transits frequently due to construction on ramp on other side of bridge tunnel. Has to be at least 15ft or more.

Thank you. Just drove through there for my visit to Carlin Canyon. The underpass is at least 20 ft tall. Had no trouble getting in or out.
