WILMINGTON, Del. — Amid intense winter weather and snowfall, 10 trucks crumpled behind one another on a Delaware bridge heading to New Jersey.

The News Journal of Wilmington reports that the 10 tractor-trailers crashed and jackknifed on the Delaware Memorial Bridge on Wednesday afternoon. Delaware River and Bay Authority spokesman James Salmon says all four lanes of the New Jersey-bound span were closed for over two hours.

Salmon says it’s unclear how the crash happened, but that it was a unique situation because of the large amount of snow that accumulated in a short time. He said the agency doesn’t expect to close the bridge to trucks.

It’s unclear if anyone suffered injuries.
