US Low Clearance POI

 

Due to the apparent amount of interest in this POI (172 downloads already) I figured it would be a good idea to get a forum topic going on it for additions or corrections.

Again, I will state here that this file's use is totally the responsibility of the user. I make absolutely no claim to its height or location accuracy. The file is to be used as a guide ONLY!

If you would like to add new locations and heights or submit corrections, please do so here.

When submitting a correction, please give the original location coordinates and height and then the corrected info.

When submitting a new location, please submit it in the format of the current POI. This will make it much easier for me to update the file.

Thanks for your interest in this POI!

NOTE: 3/13/07

Due to some user input I am completely going over this file line by line due to locational inaccuracies. Please submit only new locations that are not already within the file. Thanks!

Note: 4/29/09

Due to a lack of time to spend on updating this file, I've offered ownership of it to Firenutts. Firenutts has graciously accepted the offer and as soon as Miss POI does the transfer, he will upload an updated file. He has updated almost all of the locations for accuracies and has also added some new locations.

I would like to thank all of those who helped me develop the file initially or pointed out innacuracies or omittances (which there will always be).

I'd also like to apologize to those who've been frustrated by the lack of an update. I am truly sorry that I wasn't able to pull it off.

This is not an easy file to keep updated and/or accurate. Firenutts is going to have his hands full! I hope that all of you will help him as you've helped me.

The Low Clearance Project thread will still be available to users to provide updated locational info or comments about the project.

Again, Thanks to all and especially Firenutts for "keeping it alive."

I know this may be a loaded question, but how complete is this POI? I drive from NY to FL and have a high (13'8") boat. I was going to purchase the CoPilot but it only operates in "truck" mode. I am only concerned with low bridges so I was thinking that I could just get a loaded POI to warn me of bridges. Will this POI tell you the height of every bridge approaching?

The author is very specific not to use this file as a 'warning' system, only as a 'Guide'. He also specifies "Nor do I claim that this file is/will be all inclusive." I'd consider this as "very good advice"!

re: how complete... I have

re: how complete...

I have found both missing bridges AND bridges that are in the POI file but gone from the highway. Still... with that caveat -- I have yet to find a better collection of data for this.

Also... wrt to giving this to a technology averse person -- make sure they have common sense! If there is a sign that says "low bridge" but the GPS is silent... BELIEVE THE SIGN. Also, if the GPS is chirping at you but there are no signs - proceed with caution.

I'm going to try...

to polish this the new file off before the year's out. You'd be suprised how much time it takes to verify locations, etc. Time hasn't been easy to aquire for the past few months. I've had many e-mails inquiring if it's done yet. Quite frankly, this file will never actually be "done."

As has been noted in other posts, some spots are missing, some aren't quite where they should be, some aren't listed at all, some heights may be wrong.

Someone asked if it could be used in its current state as a general planning tool. Yes, but it may not be all that accurate.

Someone else asked if it's totally up to date and all inclusive. No. It never will be. Nor would I ever state that it would. Things change. Old stuff comes down, new stuff goes up. It's next to impossible for one person to keep track of all of it.

For those of you who've set the file up with the alarm feature turned on. If you get a warning, it's already too late. You're probably already in a situation where you can't turn around and re-route. The file should be used as a planning tool ONLY! And yes, It's possible that the underpass below the one you're on is the actual "low" underpass.

If you want to be totally sure that the route you're going to take is "Tall Vehicle" friendly, I highly reccommend that you check your route against the Motor Carriers Road Atlas published by Rand-McNally. BTW the new POI will have the most current MCRA listings included wherever possible. Even those are tough to decipher at times.

It turns out that I may have someone to help me with the file as well. Will have more on that later.

So with that, keep your eyes peeled for the new file.

Happy Holidays!

Emergency Brake? What Emergency Brake?

Disclaimers and Lost File

The best source that I'm aware of for low clearance is the truckers guide. Never depend upon any file for your high boat. It's likely that the file was never complete or accurate (that does not mean that it's not valuable or useful). Plus reading through the posts will reveal that part of the data was lost and there was no backup.

I think the low POI file

I think the low POI file would be great for truckers.

File Update

Driven1,

Good news about the pending update. I was validating an address that I had never been to through satellite images, etc. and it did take time so I can appreciate your effort. In my case the location was on the back of the property which caused the GPS to route across other buildings. With a street entrance location the routing would have been on normal streets.

Low Underpass Clearances file

Has this file been updated yet? If so, where is it located so I can download? I am interested in using it as a planning tool for planning a trip with my 13ft high 5th wheel.

Thanks

Has this file been fixed?

Other restrictions

I posted a comment on tunnels, propane, and other road height restrictions. I hadn't searched for bridges and overpasses so I missed this information. As RV'ers this is a constant concern for us.

Error in file

I just downloaded this file and installed it on my Nuvi 660. I got an error message that stated there was a formatting error on line 13, all data after that line will be ignored. I checked the file and found a lot of formatting errors involving quote marks ("). A lot of the files had a single quote mark (") after the inches number and needed a double quote mark there (""). Others had a double quote mark followed by a comma ("",) but needed a triple quote mark followed by a comma (""",). Both of these errors cause errors in the way the file is loaded and displayed. The double quote marks just insert a quote mark in the displayed text but are otherwise ignored.

I have corrected this particular error and can upload the corrected file if you like.

You like to visit runaway truck ramps during your trips? LOL LOL wink

That's good

I never saw that when I wrote it grin You know what I was thinking... If there's a runaway ramp, it's a good indicator that's a long grade; whatever goes up has to come down, you know?

Are you interested only in the down grades or are the long, slow upgrades of interest as well?

As the same hill would qualify for both depending on direction of travel would you put a POI at each end?

Possible Low Clearance Discovered accidently

I was researching Gas Stations, when I accidently discovered a low clearance bridge that I could not locate in the low clearance file. I do not know how low it is, but here is the information:

1066 Quinnipiac Ave, New Haven, CT 06513

-72.87718,41.31611

Some helpful Information

I am an Over The Road truck driver using MS Streets and Trips and the POIFactory as been awesome, i use the logitudes and latitudes and import them in to it, and I use my laptop for my logbook, gps, and email my paperwork to get paid. Here is a web page (no logitude and latitude info tho) that i use for checking my routes for low clearences along with the Rand McNally Motor Carriers Road Atlas and restricted routes for us OTR Drivers. Maybe it will be helpful or not, thought I would share something since I have used this site so much now...
