For safety, our inspectors closed the northbound bridge until the damaged support beams could be fixed. These are critical pieces that support the bridge deck. Replacement parts can't be ordered out of a catalogue, we had to custom make them from raw steel.
A team of about 30 worked in shifts around the clock to design, fabricate and install a new diagonal and vertical support beam.
After about 500 combined hours of work, the northbound SR 529 Snohomish River bridge reopened to traffic at about 12:30 p.m., Tuesday, Dec. 4. We don't roll the dice on safety. It's pretty amazing how quickly it all came together. In 81 hours, the bridge went from damaged to repaired. We closed it, stabilized it, designed replacement parts, fabricating and installed them - and only disrupting one event commute for drivers.
