Hazmat teams are on the scene of a fuel spill on southbound I-395 between Shirlington and King Street.
Nearly 50 gallons of fuel have spilled from a ruptured tractor trailer fuel tank, according to scanner traffic. Firefighters are trying to contain the leak.
All but two lanes of the main line of I-395 are blocked due to the emergency response. The ramp from Shirlington Circle to southbound I-395 is being closed.
Update at 4:30 p.m. — Firefighters managed to contain the spill in about 30-45 minutes. Before the lane closures were lifted, southbound traffic was backed up to the area around the Pentagon.
