Investigators are trying to figure out what led to a car crashing and knocking over several power lines at Northeast 21st Avenue and Columbia Boulevard Saturday night.
Portland Police say the car hit a power pole just before 9 p.m. A passing tractor trailer got caught in the downed wires.
Pacific Power crews were called out to the scene to turn off the power so that firefighters could get the truck driver out safely. The driver spent an hour in the cab of the truck, waiting until it was safe to get out.
The truck driver was not hurt. The driver of the car that knocked over the power lines was taken to the hospital with non-life threatening injuries.
Police say alcohol was not involved in causing this crash.
Pacific Power says 340 customers lost power Saturday night when the power poles were knocked over. Those customers are mostly businesses. Police closed down Columbia Boulevard from 33rd Avenue to Columbia Way.
Columbia has since been reopened and power has been restored.
