Height clearances of overpasses and bridges

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.

Federal law ,all interstate bridges must have at least 16 feet of clearance from roadway, to any useable portion of that roadway, this includes the shoulder. These rules were put in place when the interstate system was started during the Dwight Eisenhower administration. The General saw how well these roads were constructed in Germany for there war effort, thus we also started this same system, allowing rapid troop transit during an emergency . But today it is outdated, except for us who use them

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

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 bridge clearances

get an atlas like stated. typically highways are fine. remember to check for heights. main problem would be back roads. but highways and interstates are atleast 13'6.

I wouldn't bet my A/Cs & tv ant on that.

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,

There is a free "low clearance app"
Plus there is also a free website you can use.

The truckers atlas also has info. You can get it at most truck stops fo $60

The answer to your question is no... there is no height problem on your chosen route. We've driven from Kansas City MO. all the way down Hwy 65 to I-20 with our 5th wheel which is 13'4" with no problems.

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.

"generate routes based on the height and weight restrictions of roads and bridges."
