Most of the highway construction funds are to be used around Baltimore City rather than it which further encourages suburban sprawl. There has also been a recent movement to move back into cities especially young single adults and empty nesters. They, along with college students are the most likely to use transit. The worst part of it is every highway construction project takes away the likelihood of transit lines being built. Don't believe me? Well here's a list of construction projects in and around Baltimore that will take away funds and ridership for transit lines.
