The Posey Tube will be out of commission over two consecutive nights for repairs, as confirmed by Caltrans officials. The vital roadway linking Alameda and Oakland will shut down at 10 p.m. both Tuesday, March 26, and Wednesday, March 27, and won't be reopening until 4:30 a.m. the subsequent mornings. Daytime drivers can breathe easy though—the closures are for nighttime only, designed to cause minimal disruption.

Caltrans advises a detour route for the duration of the shutdown for those accustomed to slipping through the Posey Tube's subaqueous embrace during the witching hours. A statement on the Department of Transportation's website marks these repairs as vital to the "maintenance of our state’s highways, bridges, and tunnels." The maintenance work is weather-dependent, though, as a raincheck is in the cards if Mother Nature acts up.

While the Posey Tube gets its much-needed beauty sleep, the Webster Tube will keep the night owls and the graveyard shift moving without interruption. Traffic control measures, including changeable messages and directional signs, will be in place to guide the temporarily displaced traffic where nighttime drivers can't have the luxury of driving through the Posey Tube.

Expect to see California Highway Patrol officers at the scene during the closures, ensuring that travelers respect the work zones. Caltrans reminds motorists to "drive with caution," to "slow for the Cone Zone" and to "Be Work Zone Alert," in their official notice. Commuters should plan for potential traffic delays during these essential maintenance works and seek alternate routes where necessary.
