One southbound lane on U.S. 75 has reopened in Plano, police said just before 1 p.m. Thursday.
Officials said officers were working to remove the vehicles quickly so the highway can be fully opened.
A multi-vehicle crash near Parker Road caused the closure. Two semi-trucks and two other vehicles were involved, but there were only minor injuries, police said.
All southbound traffic will be forced to exit at Legacy Drive or Spring Creek Parkway before drivers can re-enter the highway at Park Boulevard, police said.
Police are also asking drivers to avoid the area at this time.
