UPDATED 8 a.m.
Traffic is slowly beginning to move.
All lanes of the inner loop of 495 are closed at Old Georgetown Road because of two accidents involving tractor trailers and a fuel spill overnight.
At 6:30 a.m. the backup reportedly was extending back two miles and some motorists were reportedly stuck in the backup for over an hour.
It may be hours before the accident is cleaned up. The best advice: avoid the inner loop during your morning commute.
