Default Bridge Clearance while trailering

I am having a Raydome installed on my boat and it will end up being 12 feet above road level. I think bringes have a 13 foot clearance so I should be fine. Anything else to consider?

Thanks

Bridges vary WIDELY from state to state and highway to highway, and there is no "13 ft above the road level" rule.

The only "rule" is on Federal highways built after 1976, and that height (clearance) is 15 ft, and most states building "state" highways after 1976 have complied with the 15 ft Federal height requirement.

Low hanging tree limbs are my biggest hazard.

If you check around, there are swing down mounts available for radar domes.

Watch the powerlines! I've come home to more than one mark on the dome! - this was before I checked clearance to all wires to and from the ramps I use.

The generally accepted level is 13' 6". If you buy a motor carrier's atlas By Rand McNally which come out yearly and can be obtained at the local truck stop and some WalMarts, it will indicate where the low bridges are. It gives the Interstates, the Federal highways and the local restrictions. I would be more worried about service stations etc--than highway bridges. I have a 2 meter ham antenna on my truck which is set about 2" above my Radar arch--if any question I go slow and listen for the antenna to scrape--that gives enough room to back out if necessary.

You should be fine.13'6" should clear power lines and overpasses,but do check.Now as someone before me posted about trees.Do watch for them.If it rains,they do hang lower,WATCH OUT!At 12',you should still be ok on most main roads.
