heavy truck underpass and bridge weights

You can search the POI files index for the low clearance file, but methinks you would be better served by purchasing a copy of the Rand McNally Street Atlas for Truckers from a truck stop. It has a much more comprehensive list of clearances and bridge restrictions than any of the POI files might have.

ok i think in the future they will be there in the poi files. only a matter of time. the boss has every line and transformer, switch, you name it on his gps. im sure they can stick on bridge weight and underpass soon

The problem you are going to run into with the clearance files here is that it isn't complete, or comprehensive.

I don't even think there is a bridge weight file. the file for each state would be nearly unmanageable.

Being an ex truck driver, I just wouldn't want to rely solely on those files. It's a heck of a lot easier to just plan your route, check the R-M book and then make adjustments. Using a POI file is going to run you almost to the bridge or underpass before it will warn you.

There is another source, sold at truckstops and online also is Co-Pilot. It's designed specifically for commercial trucks and contains updated lists of clearances and weight limits taken from the same source that R-M gets them.

You have good advice about stopping at a truck stop and picking up the printed version from Rand McNally.

Most use Excel or another spreadsheet program to create the CSV files because they are column oriented. CSV files are really text files, so you can create them in virtually any text editor. As you have a 660, you will probably want a 4 column file. Notepad will allow you to create a text file with the 4 columns, but I would suggest you get a spreadsheet program for the ease. A free set of programs that include a word processor, spreadsheet program, presentation program, and other goodies is available from openoffice.org. Download it and you will be on your way.

There are several websites that will provide you with coordinates. GPSVisualizer is one that's easy to use, and there are others. POI Verifier II and GeePeeEx Editor are two programs developed by contributors to this site and are available for a small fee.

Building POI takes a bit of practice - at least to do it efficiently. I would load up Open Office and download a couple of POI and load them into CALC, the spreadsheet program, to get a feel for how they are supposed to look. I will warn you, building POI files is a great time sink - you will be amazed at the amount of time you sink into making files.

ok im gonna start downloading programs. i wont give up till i get it. this is a great site.

is currently being worked on by driven1. I think the new file should be available shortly after the first of the year (01 Jan 2009). I personally think that bridges with limited weight would be a nightmare to create and/or maintain. This file (like most all of the other files) are tools to be used with an abundance of "COMMON SENSE". You should keep checking for "Low Clearances file update".

Hope this helps.

i will say this site is a great one. like i said before i work for a electric company. when a storm starts and there are way over 100,000 people out of power we work 30 to 60 hours straight..no sleep..in the dark..in strange towns. if this file no matter how incompleate it may be, if it saves a convoy of up to 15 bucket trucks just one time it is well worth it and could quite save a live. your site here may be a hobby an fun thing to do. but your users are helping out people in need and your not getting the thanks you deserve. so i will start by saying thank you. im still working on my own area here . im trying to find a way to download favorite from my 660 to map source waypoints that way i can just touch and save as i drive by. no luck yet.
