An 80-year-old woman was critically injured Saturday after the car she was riding in crashed into a railroad crossing sign in Tacoma, according to the State Patrol.

It happened about 11 a.m. on northbound state Route 509 at the Port of Tacoma.

Troopers are trying to figure out what caused the elderly man behind the wheel to lose control and if it was weather related.
