And to top it off - the bridge clearance is actually 11' 10.8" As stated from the website 11foot8.com
, the clearance was measured by DOT workers after a street repaving. The 11' 8" sign gives the state a 2.8 inch safety margin. The MUTCD
allows for a maximum of 3 inches difference between the signage and the actual clearance.
Plus there are signs on all the streets leading up to this bridge, as well as a trip system that turns on the warning lights before you get to the bridge if you're too tall.
It's pretty crazy how the crash bar just sweeps the roofs of all the RV's clean.
I don't know about others, but when I got our RV one of the first things I did was get up on the roof and measure from the tops of both a/c's to the ground. I then made myself a diagram that stays in the motorhome, so I know that we are:
- 10' 8" to the top of our roofline
- 11' 10" to the top of our a/c's
- 13' 4" to the top of our radio antenna (that is mounted on a spring ball)
I won't travel under any bridge that is less than 12' and even at that, I prefer to look for a way around first.
These are numbers that everyone that travels in a vehicle taller than a pickup truck should know!
