Sinkhole causes temporary closure of 710 freeway off-ramp in Pasadena

An off-ramp along the 710 Freeway in Pasadena was shut down on Wednesday, March 29, after a sinkhole developed beneath the roadway, authorities said.

The sinkhole opened on the southbound off-ramp to California Boulevard leading to a full closure of the exit, according to Pasadena spokeswoman Lisa Derderian. Traffic was temporarily diverted to the Del Mar Boulevard off-ramp.

Temporary repairs were completed on the roadway late Wednesday, allowing for the ramp to reopen one of two traffic lanes, though officials warned commuters that traffic delays would still be possible during the peak commuting hours.

Despite the overnight and morning rain, crews estimated that the pavement patching would be completed on Friday, allowing for the off-ramp to fully reopened to traffic, Derderian said.

However, daytime closures would still be a possibility next week for crews to fully complete the repairs.

The freeway sinkhole was the just most recent that have opened up following several atmospheric rivers that have dumped rain and snow across the region.

The heavy rains created two massive sinkholes in Los Angeles last month, one that closed the northbound 101 Freeway, near Spring Street, and another in the 1200 block of Elden Avenue in Pico-Union.

Earlier this month in Orange County, a sinkhole opened up in a road in Laguna Beach that led to evacuations after crews discovered the sinkhole created a gas leak and a water main break, spilling several thousand gallons of water onto the roadway below.
