On Wednesday, Dec. 4, several tractor-trailers were involved in two different accidents in Los Angeles. One truck was found at about 4:30 a.m. hanging off the northbound 710 Freeway connector to the 60 Freeway in East Los Angeles. The trailer hung there for several hours until three tow trucks arrived to remove it. Also on Wednesday, two tractor-trailers collided on the southbound 5 Freeway near the Roxford Street exit in Sylmar around 3:40 a.m. The accidents snarled morning rush hour traffic for several hours.
