Crews working to fix massive Union City sinkhole, increases in size



UPDATE: Crews Thursday afternoon are currently securing and stabilizing the sinkhole to continue to repair work of their water main, according to Union City Communications and Marketing Manager Lauren Sugayan.

The work is expected to take about 10-12 hours. The size has grown to 25 by 25 feet and is 10-feet deep.

Sugayan said the city hopes to patch up the hole by late Tuesday afternoon. The cause has not been determined.


UNION CITY (KRON) — Crews are busy fixing a massive sinkhole that is at the intersection of Alvarado Boulevard and New Haven Street in Union City.

The large sinkhole was first reported just before 2 p.m. and the roadway had been closed ever since causing major commuter troubles.

The sinkhole is estimated to by 12 feet wide and 10 feet long,” said Union City spokeswoman Lauren Sugayan.

Alvarado Middle School is located a couple of blocks away from the sinkhole and school officials said the hole will impact pick-up and drop-off traffic.

The massive hole in the ground is also causing issues for some nearby homes. About 10 homes are reported to have little of no water pressure.

The cause of the sinkhole is still unknown but some theories include a fluid leak or an incorrectly compacted pavement.

Robert Ells from the Alameda County Water District said crews are focused on fixing the water main that is located above the sewer main.

PG&E is also at the scene monitoring the gas lines underneath the road.
