Los Angeles street crews have hit the shovels to attack a perpetual problem - potholes.
Operation Pothole was held over the weekend. The Los Angeles Times says 150 workers fanned out across the city to fill about 20,000 holes.
Board of Public Works Commissioner Andrea Alarcon says such operations are usually held at least once a year but this weekend's was the largest to date.
Altogether, about 250,000 potholes are repaired annually.
Residents can call 311 to report street problems.
