A woman and child died this afternoon and another child was seriously injured in a single-vehicle crash on westbound Interstate 80 near Madison Avenue.
The three right lanes of westbound I-80 likely will remain closed for about two hours, authorities said.
The crash occurred about 2 p.m. California Highway Patrol spokeswoman Officer Lizz Dutton said a witness, an off-duty law enforcement officer, spotted a 2005 Nissan Pathfinder speeding on I-80 near Horseshoe Bar Road in Loomis and weaving in and out of the three left lanes. The witness called in and reported the vehicle.
Just west of Madison Avenue, the Pathfinder veered right, crossing all lanes and running off the shoulder into a ditch, striking a tree.

Dutton said the driver, a woman about 40 years old, and a child in a child restraint seat in the left side of the back seat, died at the scene. A girl, who appeared to be younger than 10 years old, was taken to UC Davis Medical Center with major injuries.
The victims’ names have not been released.
Dutton said the vehicle was not the subject of a law enforcement pursuit. She said she did not know whether the witness was speeding to keep pace with the Pathfinder.
