Verrazano-Narrows Bridge a little less than 2 miles long overall, Toll $11.00. Technically that is for a round trip (provided you are coming back that way) so it varies from $5.50/mile to $2.25/mile. It may be the most expensive toll access in North America.

For non-bridge/tunnel my guess is the toll on I-95 in Delaware. If my memory is right its around $5 for a I think what is 5 miles of road.
