Caltrans announced that it will close the Posey Tube for inspection and maintenance from 10 p.m., Wednesday, Feb. 17, to 5 a.m., the following morning. The tube, built in 1928, carries traffic from 
Alameda into Oakland.

Contractors currently working on a second project to rehabilitate the tube will continue with their work as scheduled. This includes repair, not maintenance work, and involves replacing guardrails and sidewalks, repairing and installing lighting and closed-circuit televisions, as well as rehabilitating the tube’s superstructure.
