Four people were injured Saturday after construction along I-805 blocked a driver from pulling over to the shoulder.
The accident caused a multi-vehicle pile up near East Palomar in Chula Vista.
Police say a woman experienced car trouble and tried to pull over to a safe place, but cement barriers due to ongoing construction along that stretch of I-805 prevented her from getting to safety.
Her disabled car led to a four-car chain reaction pileup. Officials say one person needed to be pulled from a vehicle. All of the injuries reported were minor.
