Height clearances of overpasses and bridges

[xray0111]

We are new to RV'ing and have just purchased a Class A 45' RV. with the vertical height of 12'9". Our plans call for us to travel from Jackson, MS. to Branson, MO. using I55-I40-US65. Are there any bridges or overpasses that would hinder us with the 12'9" height of the RV.?

Also, any opinions on Treasure Lakes RV Resort in Branson?

Thanks,
Xray

Exactly Truckers Atlas (I have one) is great for major roads. They don't cover backroads, say like the one that might lead to a campground. The reason is long-haul truckers don't take those and locals would know all the clearances.

You have some options. There is a place that sells a POI "add on" to a GPS that can alert you to underpasses. The down-side is it alerts you based on distance, so that low overpass may be on a side road, not the road you are on (link).
I have this and it works, and works well.

Then there are RV or trucker GPS's which have this (and sometimes more) built in.

*Garmin is going to sell (in a couple weeks) the RV-760 LMT, which has over-passes, campgrounds, etc, built in.

*Rand has a series (5510, 7710, 7715, 7720, 7725) that also have this, but the older models have a rep for crashing, freezing and dying. Hopefully they fixed this in the newer models.

*Garmin also has Trucker GPSs, that have an RV mode (but no campgrounds, etc). The Dezl series is their current line.

I would not think someone would build a campground on a road that had a low overpass...JMHO

My TT was only 11 ft. A 12 ft 6 inch overpass was no big thing.

Bridges and overpasses that were built to specifications 50 years agomay not be high enough now. Roads have been repaired and repaved many times, in some cases reducing the clearance somewhat. If an 18 wheeler at 14' can get through, you can too at just 12'6". Just send him through first. Aside from that, the route you want to take is OK, but as you travel, watch out for crowned overpasses, which may be a lot lower on the sides than in the middle.

Some of those in WA east & west north of the columbia river. I believe 12' 6" on edges. I'm at 12' 11"

A little OT, but, you are new to RV'ing but you jumped directly into a 45 footer? God Bless you sir, you are truly a brave man.:B

I would watch. For a couple of years, the vac we took, if a 18wheeler can make it we can.always have something to go back on.now it's all happy-camping

..and another thought..we've been full-timing for 16+ years and our preferred way of traveling is off the interstates and we have a 40' motorhome. We've gone to Alaska, also. We choose public campgrounds - national forests, etc. We have never 'checked' the overpasses by various means and don't use a trucker's atlas. However, we don't get into big cities (the interstates going through them are all o.k. - truckers do them all the time), but we don't get off on a small city street and wander through town. I think if you use common sense you'll really be o.k. Just think how all the delivery trucks delivery their goods to places. Good travels!!

you might talk to the gentleman that collapsed the interstate bridge
in washington last month. he was well under 16 feet.

Come to think of it, as a former OTR Truck driver, I have also seen a few big trucks delivering a bridge or two :S :h :? :E

Good point about WA. "The state DOT said there were 21 bridge-strikes involving trucks last year, 24 in 2011 and 14 in 2010." the state Does Not Guarantee Height Clearance, old article http://www.huffingtonpost.com/2013/05/24/i-5-bridge-collapse-caused-by-oversize-load_n_3331363.html

lol width is a little different than height. i recall that truck may have been oversize. and to respond to wyotraveler....ive been driving a tractor through this country for many moons my friend. i will bet my ac on it.

As others stated I agree, a truckers atlas will give the best info. However, if you are like me at all, I like to have basic info to plan immediately before I buy the hard copy and in this "online age" here is a link that should help
America's Independent Truckers' Association, Inc. - Low Clearances, Bridge Heights and below normal ...
