Crew members work tirelessly in the mud, even when they can barely walk through it, proving their job to be very difficult at times.Crews placing bridge girders on August 23.Another point of view of crews placing bridge girders on August 23.Crews complete work on one of the two piers that will support the five girders that will be placed at the end of August. The bridge will carry traffic from I-405 to westbound SR 522 over the entrance to the UW Bothell/Cascadia campus.Crews using equipment to drive in on the 1400, 50-85 foot long nails on the side of the hill.View of the future 95-foot tall soil nail wall.Crews built a rock wall to support the steep hillside slope. This will allow crews to widen the SR 522 roadway and construct a sidewalk for future crossing.We have an extensive pumping system that carries stromwater run- off to a pond. The dirty water settles before being pumped into a larger Chitosan filter system. The Chitosan system cleans the water before it is discharged into the Sammamish River. This blue pump is pre-treating the pond water through a small filter before sending it to the Chitosan system.This yellow pump is removing water from a catch basin to pipe it to the settling pond.Drivers will see plastic tarps covering the hillsides that crews have been working to clear. The tarps help to prevent rain from washing an excessive amount of dirt into the pumping systems, and ultimately, into the Sammamish River.
