SAN FRANCISCO (KCBS) — The timing of the Bay Bridge’s emergency repair on Wednesday during a San Francisco Giants’ game that caused massive gridlock has received plenty of criticism.

The emergency repair began early in the evening and prompted the closure of several lanes on both the upper and lower decks, creating miles of gridlock on San Francisco’s city streets. Caltrans officials said driver safety is always their number one priority.

“Some people thought the hole was a pothole. It in fact was not, it was a matter of a joint that had a great deal of wear and tear as a result of all the cars,” she said.

She explained that because Caltrans wasn’t clear as to what was going on that they couldn’t efficiently get the word out about the emergency repairs.

“We had to determine what in fact the issue was before making any decisions,” she said.
