Maryland State Police officials said all lanes of the outer loop of the Beltway are open as of 12:30 p.m. in Greenbelt near the Baltimore-Washington Parkway after an early-morning accident.

The north and southbound lanes of the parkway have also reopened near Route 32 in another accident.

Roads in the parkway area have been blocked in Wednesday’s morning commute.

In one an overturned tractor-trailer that was carrying garbage at 7 a.m. shutdown all lanes of the Outer Loop of the Beltway at the Baltimore-Washington Parkway in Greenbelt.

At 10:45 a.m.,police said they expect the fourth lane on the outer Beltway loop will open, as they are working to remove the tractor-trailer. It took several hours for pickup of the garbage-filled tractor truck to be completed.

One Maryland state policeman described it as “a mess” in the early-morning accident that had shutdown all four lanes of the outer loop in the Wednesday morning rush hour when the truck overturned.

The Beltway backup came as a truck driver’s threat to shutdown the roadway turned out to be a hoax.

On the Baltimore-Washington Parkway, police said at 10 a.m. that they had just re-opened all of the southbound lanes near Route 175 after they had been closed for much of the morning rush hour.

The incident occurred around 5:30 a.m.

U.S. Park Police had warned drivers to avoid the area. The southbound lanes of the parkway had bumper-to-bumper traffic approaching the closure, which lasted for several hours.

At 6:30 a.m., officials said they had to also close the northbound lanes of the parkway near Route 32 in Columbia for 15 minutes so investigators can get pictures of the accident scene. Those lanes have also re-opened.
