WOW, I have to relate the latest brilliant idea of the government of Maryland.

There have been tolls on I-95 ever since it was built. The toll has been $1.00 per automobile (more for trucks) for quite a few years. Last year, in an economy move, it was decided to raise the toll to $2.00, but collect it on only one side of the highway. So the tollbooths were removed from the southbound side and you pay the toll on the northbound side. This means it's free to enter the state (from Delaware) but it costs you to leave. I think there is a deep meaning here, but not sure what it is.
