A crash involving an empty tanker truck and three other vehicles blacked lanes on the Outer Loop of the Capital Beltway in Maryland.
It happened on northbound Interstate 495, north of Route 202, in Prince George’s County on Wednesday afternoon.
No one was hurt or transported.
Four lanes were blocked earlier, but all lanes have reopened by 6:45 p.m., as the crash activity was moved on the left shoulder. There is still a long line of delays after Branch Avenue.
“Neither the tanker nor saddle tanks are leaking — it is a combo fluid spill from the engine,” WTOP traffic reporter Dave Dildine said.
The state has sent a sand truck to clean up the fuel and fluid spill.
