High-level routing guide - given origin/destination return states travelled

We are not looking for detailed routing but more high level type of
routing.  Do you know of a way (outsource/system/program) that when given a
origin and a destination that the states travelled can be programmatically
derived?

We are running into issues with trying to manage bridge weight laws in 7
states right now.  So there are two pieces: 1.)  generate State list 2.)
work with State Bridge law table.  We can easily maintain a table on the 7
states.  Programmatically determining the states travelled on a given
shipment is a little tougher.  Any thoughts?
