The very clever folks at OneShift.com has come out with an ERP mapping program via Google Earth to allow drivers to route their driving directions to avoid (or least try to avoid) most of the money-sapping gantries.

(hint: way too many)
Check their cool map program out over at http://www.oneshift.com/erp
There is another site for ERP, more useful functions within a few clicks, easy to use too. Go http://www.TripSum.com
