Crews spent much of Monday night cleaning up the mess left behind after a Montgomery County Transit Ride On bus collided with a tractor-trailer on I-270 in Gaithersburg, Maryland.
A spokesman for Montgomery County Fire and Rescue Service tweeted photos from the scene, which at one point had all lanes blocked on the interstate just before the ramp for I-370.
The delivery truck was carrying multicolored paper products, which spilled into the roadway along with fuel during the crash.
No information has been released about what caused the crash.
