Update at 10:10 a.m. — One lane of traffic is now squeezing by to the left of the accident while crews work to clean up the spill and clear the scene. HOV traffic is backed up to Shirlington circle.
The HOV lanes of I-395 have been shut down due to a jackknifed tractor trailer that struck the highway wall divide.
Police have blocked traffic because the truck is leaking fuel and they fear it might ignite. The fuel is coming from a 100+ gallon saddle tank, according to scanner traffic. A hazmat team is being dispatched to the scene.
A long line of northbound traffic is now at a standstill in the HOV lanes.
