A main route out of Eastlake and Otay Ranch was closed Thursday morning due to an overnight water main break.
Flooding at Olympic Parkway and Heritage Road caused delays for commuters as police and city crews worked to reroute traffic.
Chula Vista Police were called just before 4 a.m. about water covering three lanes of traffic on westbound Olympic Parkway, west of Otay Ranch High School.
Otay Water District officials say a break in the recycled water line caused the flooding so no homes or businesses were impacted by the break.
As of 6:30 a.m., the far right lane was caving in so police had just that lane blocked off from traffic.
Water crews hope to have the break fix by Thursday afternoon.
