Bay Bridge Deck Replacement Time-Lapse Photography
A section of the San Francisco-Oakland Bay Bridge’s upper deck was replaced in one large operation over the Labor Day weekend. This is truly an amazing engineering feat. The Metropolitan Transportation Commission that oversees the project captured the event using time-lapse photography and posted it on their site. Below is a screenshot:
“So smooth, it was like sliding in a drawer. That’s how one local news organization described the delicate process of rolling in a new 6,500-ton segment of the upper deck of the San Francisco-Oakland Bay Bridge over Labor Day weekend. The operation also was remarkably fast, with the installation taking a little under three hours, about half the time originally predicted. In fact, nearly every aspect of the complex retrofit-by-replacement just to the east of the Yerba Buena Island Tunnel was so well-orchestrated that Caltrans and the Bay Area Toll Authority (BATA) were able to shave 11 hours off the schedule, and reopen the bridge to traffic at 6 p.m. on Labor Day proper — far ahead of the original deadline of 5 a.m. on Tuesday.”
