The George Washington Memorial Parkway was fully reopened Saturday afternoon after the repair of a 10-foot-deep sinkhole that had caused closures over two days, officials with the National Park Service said.

Crews worked overnight in McLean to fix the 12-foot-wide and 30-foot-long sinkhole, which officials said was caused by a broken storm-water pipe deep below ground.

The parkway in both directions near Turkey Run was closed for nearly five hours on Friday morning. Southbound lanes reopened by midday, but northbound lanes remained closed until around 2 p.m. Saturday.

Crews worked overnight, officials said, putting more than 350 square feet of new asphalt over the hole after the damaged pipe was excavated. Sinkholes are common after heavy rains, like the storm that hit the region Thursday.

In coming weeks, the Park Service will repair damage to the median and monitor the area for settling, officials said, which will require some nighttime lane closures.

One driver traveling northbound just before 6 a.m. Friday hit the sinkhole and lost control of the vehicle, according to the Park Service. The vehicle hit a stone wall and stopped just off the side of the parkway. The driver was evaluated by paramedics on scene but declined medical treatment.

The Friday morning closure had a major impact on commutes, with northbound traffic diverted to Chain Bridge Road and southbound traffic prevented from entering the parkway from the Capital Beltway.
