Maryland State Police in Rockville said traffic is now flowing smoothly after a tractor-trailer jackknifed this morning on the inner loop of the Capital Beltway, shutting down all lanes between the Connecticut and Georgia avenue exits for several hours.

The closures led to extensive backups and delays for the first part of the morning commute.

The inner loop of the Beltway has reopened between Connecticut and Georgia avenues in Montgomery County after it was shut down for two hours early Monday because of a jack-knifed tractor trailer.

Maryland State Police said the accident happened around 3 a.m., near the Mormon Temple. There were no reports of injuries.

Officials said crews worked to remove diesel fuel that spilled onto the roadway.

For most of the early morning, vehicles approaching the closed section of the Beltway were parked in bumper-to-bumper traffic. Delays persisted after the road reopened. Police advised drivers to use alternative routes.
