Built in 1927, the Carquinez Bridge was utilized by more than 60,000 cars per day. Seismic problems led to its replacement. Silverado was contracted by California Engineering Contractors to demolish the old structure. Silverado removed the concrete deck and steel stringers on the suspension span totaling over 10,000 cubic yards of concrete and 2,500 tons of steel, safely and on time.
Silverado removed three elevated approach ramps to the Carquinez Bridge. The existing eastbound and westbound on ramps and the westbound off ramp. The connecting ramps were approximately 1,200 feet long concrete spans on steel composite girders. The westbound off ramp to Crockett was a 900 foot long steel truss bridge. All told, over 3,000 tons of steel and 10,000 cubic yards of concrete were off hauled for recycling.
