There is no solution to this problem that I'm aware of and I have worked
extensively with the Tiger data over the last 10-12 years. The data does
not exist in the Tiger data set, unfortunately. You will also note that
one-way road information does not exist, so you are likely routing down
the wrong side of dual lane digitized interstates also.
