Pictures show an eerily empty toll plaza, an eerily empty bridge, and stuffed BART trains. Meanwhile, a car thief blew through barricades in San Francisco and led police on a chase over the closed bridge, and most people in San Francisco today completely forgot there was any problem at all, since it’s a gorgeous, sunny, warm 1st of November.

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.

Meanwhile, a UC Berkeley engineering expert was being quoted in news reports saying the design of the first fix — which was done while crews were cleaning up from the mammoth Labor Day re-route — was “not correct” and left the span vulnerable to complete collapse in the event of an earthquake. It was nothing more than a Band-Aid, he said.

An Associated Press article quoted a driver as saying the accident yesterday had caused her to lose “so much confidence in the experts, the millions of dollars that are being spent to reconstruct and build a new bridge,” referring to the decade-long project that will eventually replace the entire cantilever section with a suspension bridge.

The failure was probably caused by continuous heavy winds this week, CalTrans said. Wind continued gusty today while a new repair was being worked on. Asked to describe what the new design was like, a CalTrans spokesman said, “Think of a big belt around a piece of wood.”

Somehow that image doesn’t comfort me.

California Highway Patrol officers are still working, two hours after the incident, to clear heavy traffic from the bridge, after which it will be closed in both directions indefinitely. Monitor the Twitter account @baybridgeinfo for information.

Update: All westbound lanes reopened a little after 8 pm tonight.

A Safeway truck flipped around 2:30 this afternoon after encountering the new S-curve on the Bay Bridge, leading to these pictures: a parking lot on the westbound incline, and a completely empty stretch of roadway after the site of the crash, just before the Yerba Buena Island tunnel.

The driver, who suffered a bruised leg, was driving 55 mph in the 40 mph zone and did not know the speed limit had been changed. He said he had not driven over the bridge since before Labor Day and was taken by surprise by the S-curve.

“Everything went perfect” with the emergency repair job to the span, said Dam Himrick, president of bridge contractor C.C. Myers.

The illustration, from ktvu.com, shows Highway Patrol cars leading the first traffic across the bridge at sunrise this morning.

The unforeseen problem may delay the scheduled 5 a.m. reopening of the bridge to commuter traffic on Tuesday morning.

CalTrans said this morning it has no estimate for when the bridge may reopen.

Wasn’t Schwartzenegger elected by promising not to do business as usual?

A tentative agreement between BART and the Amalgamated Transit Union (ATU) has been reached that must be voted on by union members within a week or so. In the meantime, BART will run as normally scheduled this week.

San Francisco Mayor Gavin Newsom, U.S. Rep. Barbara Lee, and others were present at the announcement.
