On a recent weekend, drivers stopped at a Pennsylvania Welcome Center, just north of the Maryland line, to take a break on their trips. Cars and trucks whizzed by on Interstate 83. Peter and Jackie Speaks, who were on their way home to Harrisburg, said they recognize the challenge the state is facing with its deteriorating roads and bridges. They’ve heard about plans for tolls to pay for work needed, but they don’t know if that’s the answer. Jackie Speaks motioned to nearby tractor-trailers parked at the rest stop and mentioned how much harder new tolls would be for the industry.
