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.

I don't know because I would get off at RT 273 in Newark and cut down Elkton Rd to Maryland and get back on.

BTW it's probably about 15 miles. As a native, it was wonderful when they put the toll on the State line only.
