Original story

Motorists and commuters may have seen a huge delay on the Dulles Greenway this morning due to a overturned tanker truck that caught fire around 5:30 a.m., according to Terry Hoffman, public relations manager for the Greenway.

According to Hoffman, the driver of the truck may have fallen asleep at the wheel or lost control, causing the truck to overturn. The accident has closed the Greenway between Belmont Ridge and Shreve Mill roads.

The driver was flown to Inova Fairfax Hospital. According to a statement released by the Virginia State Police, the driver’s injuries were serious, but not life-threatening. 

Currently, all westbound lanes of the Greenway are closed, Hoffman said, and are expected to open by 2 or 2:30 p.m.

Hazmat crews are on scene pumping fuel from the tanker truck and Hoffman said this incident will most likely not affect the evening rush hour traffic.

For detours on the Greenway to bypass the accident, Hoffman said motorists should take the Shreve Mill Road exit, with no charge.
