BALTIMORE, Md. (CBSDC) - A fiery and fatal crash late Thursday night had I-95 Northbound closed at I-395 just outside of Baltimore into much of the early morning commute.

D.C. commuters had to find another way into downtown Baltimore. The cause of the road closure was an explosive tractor-trailer crash that took the life of the driver.

Fire officials said the crash happened just before 11 p.m. Thursday evening just outside of Baltimore’s downtown. They say a tractor-trailer carrying lumber struck the barrier wall that separates northbound I-95 from I-395.

The collision ruptured the saddle tanks of the tractor-trailer causing the diesel fuel inside to ignite, according to fire officials.

The driver was pronounced dead at the scene. Investigators are still uncertain if the driver died from the injuries suffered from the collision or from the explosion that followed.

There were no other injuries reported.

Cleanup crews were working all night trying to rid the road of widespread lumber and spills of diesel fuel.

Police say I-95 Northbound will remain closed just outside the city to allow the road to be cleared of all debris and diesel fuel.

Drivers commuting to Baltimore were being diverted at the I-695 interchange, until all lanes of I-95 were reopened at around 6:30 a.m Friday morning.
