Two southbound lanes of the 2 Freeway in Glassell Park remained blocked late Tuesday after a collision involving a tanker truck and several other vehicles, authorities said.
The No. 1 and No. 2 lanes were closed at Fletcher Drive, and traffic was backed up at least to the 134 Freeway, authorities said. There was no estimate for when the lanes would be reopened, said Officer Tony Polizzi of the California Highway Patrol.
The No. 3 and No. 4 lanes were opened, officials said.
The collision involved four vehicles, including a large tanker carrying milk that overturned, according to Margaret Stewart, a spokeswoman for the Los Angeles Fire Department.
At least three people were trapped in two of the vehicles, and firefighters worked to rescue them.
A total of seven people were injured in the crash and taken to the hospital, and of those, three people were in critical condition, Stewart said.
