UPDATE:  Authorities reopened the Bay Bridge to all traffic about 7:20 p.m., Maryland Transportation Authority officials said.

UPDATE: The Bay Bridge was reopened to passenger vehicles only just after 6 p.m. Trucks are still restricted and being diverted prior the bridge, Maryland Transportation Authorities said.

Maryland transportation officials said the Bay Bridge is closed in  both directions because of sustained high winds and an accident involving an overturned tractor-trailer. Just before 3 p.m., officials said they could not say when the bridge would reopen.

The accident with the tractor-trailer happened on the westbound side of the bridge about 2 p.m., according to Cheryl Sparks, a spokeswoman with the Maryland Transit Administration. She said the tractor-trailer was not hanging over the side, as some had reported on social media outlets. The tractor-trailer is “not on the main span” of the bridge but near the end of the westbound side, Sparks said.

The eastbound side of the bridge is closed due to high winds. The bridge is shut down when there are sustained winds of over 55 mph, according to Maryland transportation officials.

She said it was unclear when the bridge would reopen in either direction, noting that emergency personnel were working to clear the tractor-trailer off the span.

“It all depends on the wind speeds and until we can clear the incident,” she said.
