As far as I can tell, no MD tollbooth has been erected at the state line. As of August 2010, when I last drove up there, there were just the Susquehanna River tolls in MD and the state line tolls in DE.
...and those two toll plazas have been there for as long as I can remember. They were there when I first went to Philly in 1979, and were certainly there years prior to that time.
You are correct; there’s the Susquehanna River toll north in I-95 (currently $5.00), and on the Delaware side of the same road, both directions (currently $4.00). Going south, I take the backstreets around the Delaware tolls and get back on I-95 just after crossing the state line. Going north, I used to take the Bay Bridge and pay only $2.50, then go east on U.S. Route 50 until I reached U.S. Route 301, where it connected with I-95 just past the Delaware toll, and avoid both the MD and DE tolls. I may need to reconsider my alternate route now. Have any ideas?
Wrongo. Try driving north on I95. Hold onto your wallet.
