Ok, I live in Elkridge MD about a mile or two from the crash site. Here is what happened:
A Propane tanker was merging from I-895 onto I-95 when it lost control and fell off the side of the overpass and landed on two passenger cars. Then the Propane tanker was hit by another tractor trailer carrying about 4000 gallons of gasoline which caused it to explode.
It's a big mess....you can smell it at my house. All the alternate routes are all jammed up....Rt. 100, Rt. 1, 295, Rt. 29, etc.
