WASHINGTON (WUSA9) -- Two southbound lanes of I-95 before Route 17 have reopened in Stafford where a passenger bus overturned.
Virginia State Police say the crash involves a commercial passenger bus with 54 people on board. We're told at least four people suffered serious injuries and have been transported to a nearby hospital.
On I-495 north before Route 50, two lanes are blocked due to a jackknifed tractor trailer.
