Dump truck cleared from U.S. 29

3:15 p.m. Update: The scene has been cleared, and traffic is once again flowing smoothly.

2:05 p.m. Update: Montgomery fire and rescue spokesman Capt. Oscar Garcia said the single-vehicle accident is in the 9200 block of Colesville, and is closest to the Sligo Creek Parkway intersection. The man driving the dump truck climbed out of the cab of the truck on his own. He had no significant injuries, Garcia said, but was "transported to the hospital as a precaution."

Delays may last for a couple of hours. Garcia said it probably would require cranes to remove the dump truck, which is laying in its side.

1:25 p.m. Update: There are serious delays buiding on southbound U.S. 29. Avoide the area and try an alternate route, such as New Hampshire Avenue.
