Update at 1:05 p.m. — The eastbound lanes of Route 50 have reopened after the earlier wreck involving a sewage tanker. According to Arlington County, the sewage that leaked from the tanker into a storm drain will enter Four Mile Run south of I-395, via the Lower Long Branch stream. Parks and streams north of I-395, including Jennie Dean Park in Shirlington and Barcroft Park, will not be impacted by the sewage spill, the county said.

Earlier: Eastbound Route 50 is closed in the area of Fillmore Street due to a serious accident involving a sewage truck.

The accident happened just before 7:00 a.m. A sedan and a sewage truck somehow collided, injuring five and causing raw sewage to leak from the truck.

There were five people inside the sedan at the time of the accident, according to Arlington County Chief Fire Marshal Daniel Fitch. Two had to be extricated by firefighters. In all, three were transported to Fairfax Inova Hospital with serious injuries, and two were transported to Virginia Hospital Center with minor injuries.

Sewage from the truck, which hauls human waste for a portable toilet company, has seeped into a storm drain, Fitch said. Hazmat crews are on scene attempting to contain the sewage.

Eastbound Route 50 will remain closed “until further notice,” Fitch said.
