Are the roads maintained by the city? If so, How can they barricade access to Mount Vernon is it is not paid for with gov’t money?
No, the Mount Vernon Parkway, the bike path, and land to the riverbank is part of a long, skinny, federal park that runs from Jones Point Park in the City of Alexandria through Fairfax County to Mount Vernon. Any offence committed there, including speeding on the parkway, goes before a federal magistrate at the EDVA District Court in Alexandria.
