A gravel truck overturned on the Mario Cuomo Tappan Zee Bridge early Wednesday morning, causing significant delays for Hudson Valley commuters. The crash involved two other cars and left the truck on its side, spilling gravel and closing the left and center southbound lanes for several hours. Traffic delays extended for miles and lasted between 90 to 120 minutes, though the situation improved by the afternoon. No serious injuries were reported, and the cause of the crash is under investigation. Alternate routes suggested included the Bear Mountain Bridge and the George Washington Bridge. Cleanup efforts were ongoing and involved multiple agencies to restore normal traffic flow.
