A pickup truck struck a man walking at Scott Circle on Wednesday afternoon in Northwest Washington, forcing authorities to shut down a nearby street and causing traffic delays, D.C. police said.

The accident happened at the circle at 16th Street, about six blocks north of the White House, about 3 p.m., said Officer Hugh Carew, a police spokesman.  The victim was taken to a hospital with  head injuries that were potentially life-threatening, police said.

The accident damaged a traffic light and pulled down cables in the area. Authorities closed nearby lanes of Rhode Island Avenue and suggested that commuters avoid the area.
