Sinkhole on Oakland Side Leads to Closure of Posey Tube

Both lanes of the eastbound Posey Tube were closed to traffic after 10 a.m. Monday morning until midnight Tuesday to repair a sinkhole, according to the city of Alameda's Public Works department.

Caltrans officials confirmed late Monday night that the work was completed and the tube reopened at midnight.

At least one lane of traffic was open through 10 a.m. Monday, the department said in an alert Sunday night. The department initially warned residents to expect significant delays until repairs are made, which may last through the week but may finish sooner if weather cooperates.

The sinkhole opened up after an underground storm drain failed on Saturday, the department said. Oakland Public Works is completing repairs on the roadway, per Alameda Public Works. The Posey Tube begins on Webster Street in Alameda and goes underneath the Oakland Inner Harbor to connect with Harrison Street in Oakland.

The Alameda-Contra Costa County Transit District said several of its lines will be rerouted due to the repairs. AC Transit said to expect peak commute times to be congested due to the repair work.

Westbound lines 19, 20, W and O, and northbound lines 51A, 851 and 96 will have detours leaving Alameda beginning Monday morning. The agency advised commuters to allow for extra time during the morning and evening while the repairs are completed.
