Engineers were continuing to test the completed fix-to-the-repair on the suddenly dubious Bay Bridge today, and CalTrans announced at 10:00 a.m. today that the bridge would remain closed throughout the Friday evening commute. It could possibly open as early as late Friday evening. You can click the map at left for a current traffic map or go to 511.org.

You can text the word ALERT to 45227 (which is KCBS radio) and get a text message when the Bay Bridge reopens.

Update, 3:20 pm: The 511.org site now says the bridge will be closed “through Friday,” but “if” the bridge remains closed, BART will run hourly all-night service to the East Bay tonight and Saturday night. Here’s the all-night BART details. Note that only 14 stations will be in operation overnight.
