All southbound lanes of the Dallas North Tollway were closed near Interstate 635 Thursday afternoon after a large object blocked several lanes, bringing rush-hour traffic to a standstill during the evening rush hour, according to officials.
The North Texas Tollway Authority warned drivers to expect heavy traffic and major delays through the evening commute and urged motorists to avoid the area near the Galleria.
An employee for The Dallas Morning News said the object appeared to have fallen from a large truck just north of the interchange. Traffic stretched for what appeared to be miles in the southbound lanes behind the item, the employee said.
Authorities did not immediately identify the object, say whether anyone was injured or estimate when the tollway would reopen.
