The California Department of Transportation (Caltrans) announced recently that it will close the Posey Tube for maintenance and servicing from Alameda into Oakland on Thursdays through August of this year, from 10 p.m. to 5 a.m. the following morning.

The pedestrian walkway will also be closed seven days a week, 24 hours a day. Baystar Shuttle Service is available for pedestrians traversing the tube by calling 401-4657. Detours will be in place.

Motorists are advised to expect delays and encouraged to take alternate routes if necessary and also that traffic fines are doubled in construction zones.
