 Traffic and weather on the 8th to Dave Dildine in the WTOP Traffic Center. Montgomery County Fire Rescue and MDOT with their hands full on the Beltway in Bethesda. It is a jackknife tractor trailer, a large fuel spill, and an extended duration incident. Outer loop of the Beltway jammed west of Old Georgetown Road. It happened, where they often do, on the curve above the I-270 spur. Single file to the right, getting by hazmat crews and the damaged truck.
