A proposed change to the way Virginia allocates its road maintenance dollars could more than double Northern Virginia’s share of money to fix potholes and worn roadways, according to a transportation advocacy group’s analysis.

Later this month, the Commonwealth Transportation Board plans to consider shifting how it funds pavement maintenance on the state’s nearly 58,000 miles of roadways. The Northern Virginia Transportation Alliance estimates that the change could mean the region’s share of the Virginia Department of Transportation pie would increase from about $37 million a year to about $84 million.
