Legend in my own mind
The OP said he has EZ Pass MD, which gets him across the I-95 bridge into Ceciltucky. What he doesn't have is EZ Pass DE, which gets him across the border. If you take the "red" route above, you will have the least issue in trying to defeat that toll. I grew up in that area, and work in that area. I am there right now, in fact.
EZ Pass is EZ Pass. It will get you through any place that will accept EZ Pass. I have used my EZ Pass from MD going out west many times through Pennsylvania, Indiana and even Illinois. The OP said he is tired of paying the high tolls and wanted to know if there was a shorter route of bypassing the toll other than going down Rt 4 to Elkton Rd.
