Bay Bridge Labor Day 2009 Slide Out Demolition

Silverado Contractors completed the separation of a 300 foot long section of the San Francisco Bay Bridge ahead of schedule. Once the bridge was fully closed Silverado's crews went to work. Silverado's subcontractor Fonseca/McElroy Grinding Company removed all asphalt from the section while Silverado's crews began torch cutting the steel and breaking slots in the concrete deck. Silverado's subcontractor Bay Line Concrete Cutting sawcut the deck at the east end and sawcut a one inch slot midway through the span to allow the bridge to flex once it was jacked. The separation was completed in 12 hours with no injuries. Silverado remained on site while contractor Danny's Construction Co., Inc. (DCCI) installed steel plates and tie rods on the abandoned bridge section to allow for the removal of the separated section. Jacking contractor Mammoet, then prepared the section to slide out. Once the section was jacked to 100% the Silverado workers torch cut the last of the bolts heads and made the final separation. The bridge section was then jacked off its supporting piers and began sliding out. After the section was completely slid out Silverado workers torcut the bolt treads to make way for the installation of the new detour span.
