A two-vehicle head-on crash snarled traffic during rush hour on Wednesday (March 30) morning at Stanford Avenue and El Camino Real.
Two drivers trying to maneuver around road barriers at a construction site on the corner smashed into each other, injuring a 71-year-old female driver, a Palo Alto Fire Department spokesman said.
One vehicle tried to make a right turn from El Camino and the other attempted to make a left turn from Stanford Avenue when the two collided.
A red four-door Kia sedan at the scene had a smashed-in front end.
The 71-year-old woman complained of chest pains caused by the sudden constriction of her seat belt and was transported to Stanford Hospital, the fire department spokesman said.
The vehicles were cleared from the roadway by 9:30 a.m.
