Four hours after a three-vehicle crash on the George Washington Parkway injured three people, the parkway’s southbound lanes were still closed between VA-123 and the Spout Run Parkway at 7 p.m., authorities said.

One of those injured was flown to a hospital with serious injuries, said Lt. Richard Butler, a U.s. Park Police spokesman. The other two people were sent to hospitals with less severe injuries, he said.

The collisions happened at about 3 p.m. near the second overlook, just north of Spout Run, Butler said. One vehicle overturned and a second careened into the trees, Butler said.

Police closed both northbound and southbound lanes as they flew out the injured and investigated the crash. But the northbound lanes reopened by about 4:30 p.m., Butler said. Police continue to investigate in the southbound lanes as of 7 p.m.
