From VDOT:
THREE MAJOR PARKWAYS NOW PRIMARY ROADS
New route numbers and funding for Fairfax County, Prince William, and Franconia-Springfield parkways
FAIRFAX—The Commonwealth Transportation Board approved the transfer yesterday of the Fairfax County Parkway, Prince William Parkway and Franconia-Springfield Parkway to primary roads, making them eligible for new funding and maintenance priorities.
As primary roads, the routes can receive federal funding for paving, guardrail, bridge improvements and other projects. Federal funding typically covers 80 percent of the cost to maintain interstates and primary roads, with the remaining 20 percent from state funds.
The Fairfax County Parkway (Route 7100), which runs from Route 1 to Route 7, will be renamed Route 286. The 32-mile road carries between 22,000 and 75,000 vehicles per day.
The Franconia-Springfield Parkway (Route 7900), which runs from Beulah Road to the Fairfax County Parkway, will be renamed Route 289. The 4-mile road carries between 53,000 and 57,000 vehicles per day.
The Prince William Parkway (Route 3000), which runs from Route 1 to Route 234, will be renamed Route 294. The 16-mile road carries between 25,000 and 54,000 vehicles per day.
