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.
