The San Francisco-Oakland Bay Bridge will continue to be closed after a cable fell apart Tuesday evening on the upper deck of the bridge.

Caltrans spokesman Bart Ney said he doesn't know exactly when the bridge will reopen as they are still placing everything in and testing the new system.

"We're doing everything we can to bring the bridge back into public service in the safest way for our workers and the motoring public," said Ney in e-mail Wednesday afternoon.

Bay Area Rapid Transit spokesman Linton Johnson said in a press conference that ridership increased nearly 50 percent as a result of the bridge's closure. Usually BART would generate about 55,800 riders on a typical Wednesday, but today there were about 83,000 riders said Johnson.

Johnson also said that he is not sure if they will provide overnight service as they are a "big money loser."

"What may be more beneficial...is to provide on-time reliable services during our normal commuting hours," said Johnson.

SF State art student Ally Ottesen said while BART was more crowded than usual, she didn't have a problem finding a seat.

"The worst part was taking the shuttle to school," said Ottesen, who added that because the line of the shuttle was long, decided to pay $10 for a cab to get to school.

The cable on the bridge broke off around 5:30 p.m. near the new S-turn section, where it hit several cars but no injuries were reported according to abc7news.com.

The parts that fell were part of the emergency repair that delayed the bridge from opening during the Labor Day weekend. A tie rod cracked due to fatigue and caused the crossbar and another tie bar to fall from the assembly and onto the deck said Ney.

"We are enhancing the original design to keep vibration from causing fatigue to the tie rods," he added.
