Visitors and downtown employees can park free and take a free shuttle from Market Street. (Take Exit 7 from Interstate 95. The lot will be on your left.)
The shuttle will run every 10 minutes Fridays and Saturdays from noon to 1:30 a.m. and Sundays from noon to 11 p.m. until the end of the year. Through August, the shuttle also runs Thursdays from 4:30 p.m. to 1:30 a.m.
The shuttle circulates between the 120+ space parking lot at the Connect Community Church on Market Street and the Hanover Street bus stop adjacent to the High/Hanover Parking Garage.
For more information, including where the shuttle is right now (during operating hours), see shuttle web page.
