Update, 5:30 p.m. – Fairfax County Police have re-opened Reston Parkway and Fox Mill Roads in all directions. However, traffic will likely be impacted throughout rush hour.
Update, 4 p.m. — The roads are still closed heading into rush hour. If you are planning to head that way, use Fairfax County Parkway or other routes as an alternative.
Reston Parkway is blocked in both directions from Glade Drive to Fox Mill Road as of 1:15 p.m. Thursday due to emergency repair of a gas line.
Fairfax County Police said construction crews hit a four-inch gas line on Fox Mill near Reston Parkway just before 1 p.m. Crews are working to repair the leak, but it may take more than an hour.
Westbound Fox Mill also closed until the leak is repaired, police said.
