No injuries reported, after two tractor-trailers collide, in high wind conditions, on the Chesapeake Bay Bridge near Baltimore.

Two tractor trailers collided on the westbound span of the Chesapeake Bay Bridge shortly after noon Wednesday, closing the span to traffic and bringing environmental officials to the scene for a fuel spill.

Hours after the crash, westbound traffic was backed up for about 3 miles as cars creeped by in the left lane, which was opened and closed multiple times as tow trucks maneuvered to free the tractor trailers from one another.

"The one was kind of wedged into the other one," said a spokesman for the Maryland Transportation Authority. Both trucks remained upright.

Several minutes before the accident was reported, officials had instituted a wind restriction on the bridge because gusts there had reached between 40 mph and 49 mph. The restriction prohibits tractor trailers without heavy loads from crossing.

A spokesperson said after the incident that it was too early to determine whether wind played a role in the accident, or whether the two tractor trailers involved were heavily loaded with cargo.
