A tractor trailer rolled over following a collision between Connecticut Avenue and 355 on the outer loop of I-495 at approximately 6:45am Saturday morning, according to Montgomery Fire and Rescue Services (MCFRS) PIO Pete Piringer. One adult was being evaluated for non life-threatening injuries.
Though the cargo was non-hazardous, a HazMat crew was on the scene to help with the pumping off the remaining fuel and to deal with other fluid spillage. The two right lanes of the outer loop of 495 were closed for an extended period of time on Saturday morning.
