Caltrans workers have compacted a sinkhole that opened up in Mission Valley early Wednesday morning.
The hole was 3 ft. wide by 10 ft. deep on the eastbound I-8 Taylor St. off ramp. A motorist called the CHP to report the hazard at about 1:30 a.m., according to CHP officials.
When authorities first responded, the hole appeared to be relatively small - about four to six feet deep - said Steve Caville, spokesman for Caltrans.
"The sinkhole didn't look very imposing before we started digging to find the source of the the hole."
Geologists believe the hole was probably caused by a sewer line installed about 8 months ago. They believe the incident is isolated, and shouldn't cause other sinkholes in the area, said Joe Hull, Deputy District Director for Traffic Operations.
