CalTrans Plans Fall Closures of Bay Bridge Bicycle/Pedestrian Path
To Support Demolition of Remaining Old East Span Piers
Oakland - August 21, 2017
Caltrans today announced the demolition schedule for the remaining 13 marine foundations of the original East Span of the Bay Bridge, including a series of implosions anticipated over several weekends this fall, with a projected completion date by the end of 2017. The series of implosions to demolish the 1936 concrete structures are scheduled for six weekends, starting Labor Day Weekend, September 2, and then every other weekend through mid-November 2017. Caltrans will be combining multiple piers on certain demolition dates, allowing the demolition work to be completed a year ahead of schedule, saving taxpayers nearly $10 million.
“The innovative demolition acceleration plan is a win for this project on several levels,” said Caltrans Director Malcolm Dougherty. “Not only are environmental resource agencies on board, but we are looking at a year in time savings and millions of dollars in cost savings for the public.”
For security and safety, Caltrans will also close the bridge’s Bike & Pedestrian Path between Yerba Buena Island and Oakland for security and safety the week before each scheduled implosion. A calendar of Path closure dates developed by the San Francisco Bicycle Coalition is found below.
Significant environmental monitoring will take place pre, during and post blast, including water quality, sonar, marine mammal and fish. This time period from September through November provides the window when the least number of fish and marine mammals are present in the area. There will be brief impacts to water quality, as turbidity is expected to dissipate in just over an hour. Studies conducted from 2015 and 2016 implosions showed minimal impacts to marine mammals and fish due to the blasts.
