Bridge Repair

Bridge Repair:

Last week we did some emergency bridge repair for CalTrans. The job started at midnight with three of four lanes shut down. One of the finger joints on the Carquinez Bridge had a cracked plate covering the joint and needed to be replaced before it lifted and caused an accident. Using grinders and a plasma cutter we removed the old plate that was 3/8″ thick. We prepared and installed a thicker plate at 5/8″. After preheat was applied, the new plate was welded into place using 5/32″ 7018 rods fresh out of the rod oven. It was a pleasure working with professionals that value safety on the job.
