Default Low Clearance Solutions

I have been trying out various low clearance avoidance tools after witnessing a horrible accident and having a close call myself. Obviously I look out for the signs ahead, but not all bridges are posted and it's no good for planning a route anyway.

So what are the options?


Rand McNally Motor Carrier Road Atlas

Pros - Much more than a low clearance list, with an abundance of useful information.

Cons - Limited to just over 1000 low clearances. Can't use while driving. Costs around $50.

POI-Factory.com low clearance POI database for GPS

Pros - Free to download. Accurate. Ready to install.

Cons - Limited data, not much more than 300 entries.

Available at: http://www.poi-factory.com/node/1154


DiscoveryOwners.com low clearance POI database for GPS

Pros - Free to download. Accurate.

Cons - Limited data, approximately 400 entries. Many duplicates across several databases. Only available in text format.

LowClearances . com low clearance POI database for GPS

Pros - Huge database, up to 10 times larger than the others available. Accurate. Regularly updated. Ready to install.

Cons - Costs $20 for annual subscription.

Available at: Blocked



There are also a few fully integrated GPS systems available, but these are very expensive and I cannot vouch for their accuracy or the number of low clearances in their databases.

Hope this is of use.

Nice work! If only there was a way to merge the free databases and weed out the duplicates... sounds like a project that we could all benefit from. Is there a way to divvy this up among interested members?
