Rumble strips are supposed to alert drivers, when regular warnings or signals just won’t do. Come to think of it, we’ll take some strips to slow down Moraga Avenue speedsters leaving the Warren Freeway. Nothing else has worked yet!
Unfortunately, new strips installed on the Oakland Bay Bridge haven’t been greeted with open arms. “This is the last place you want to put rumble strips, because rumble strips cause very serious vibration,” declared Hassan Astaneh, a Berkeley mechanical engineering professor. And vibrations contribute to possible bridge failures, like last year’s eyebar collapse.
According to ABC7 News, Caltrans spokesman Bart Ney begged to differ. “There’s nothing about the rumble strips that cause any type of damage to the east span of the Bay Bridge,” explained Ney. “The addition of a 3/8 of an inch doesn’t cause any measurable short-term fatigue. ” But we’re already fatigued, and will keep our fingers crossed.
P.S. We weren’t kidding about rumble strips for Montclair arterials, like Moraga Avenue.
