St. Charles Parkway
St. Charles Parkway is an unnumbered county road in Charles County. It begins at an intersection with U.S. Route 301, here called Rosewick Road and heads northeast, bypassing the commercial center of Waldorf. Its name changes to St. Charles Parkway after meeting Radio Station Road, and the route services multiple villages in St. Charles before ending at an intersection with Maryland Route 5 and Maryland Route 5 Business, with MD 5 taking over the roadway as Mattawoman-Beantown Road.
