The Washington State Department of Transportation is using a ‘pipejacking’ technique to drill out and replace two culverts beneath State Route 305 near Johnson Road. Contractor Frank Coluccio Construction will install a 10-foot culvert and 12-foot culvert expected to improve migratory fish use in Bjorgen and Lemolo creeks. Crews do most of their work below road level so traffic is seldom disrupted. The project costs $3.8 million and is being paid for with funds from a 2005 gas tax and other state and federal dollars. Crews have been onsite since July 12. Visit wsdot.wa.gov to learn more.
