Freeway lanes reopen as crews fix sinkhole
The 20- foot- deep pit opened on the right shoulder of Interstate 8 in San Diego.
Two lanes on eastbound Interstate 8 in San Diego have reopened as crews repair a large sinkhole near San Diego State University.
The hole opened on the right shoulder of the freeway Thursday, snarling traffic for miles as crews worked to repair the pit.
The hole, estimated to be 20 feet by 30 feet, and 20 feet deep, formed between College Avenue and Waring Road about 10: 10 a. m., California Highway Patrol Officer Tommy Doerr said.
Lanes closest to the sinkhole remained closed in case the cavity widens underneath the freeway, Caltrans spokesman Edward Cartagena said.
Crews later learned the space had spread about 2 feet under the farthest right lane.
A Caltrans geologist will analyze the sinkhole and the surrounding area to try to determine what caused it, Cartagena said. An irrigation pipe that was exposed when the hole formed was not in use.
The eastbound Waring Road onramp, which initially was closed, also reopened Friday morning. The remaining blocked lanes were scheduled to stay closed until late Friday as workers f illed the hole and repaved the interstate.
