Snohomish River Bridge


Building a new Snohomish River Bridge posed multiple challenges including the 300′ clear span and the inability to close Highway 2 during construction. Due to the challenges facing the reconstruction of a new bridge, this project had been in the works for 20 years. With planning and ingenuity, Apex devised a plan to overcome both obstacles. Apex built the new bridge in 150′ lengths and developed a launching system to attach each section of bridge, With a 100ft launching nose tapering from 10′ to 2′ and a pulley system with long tethers to guide the bridge pieces in , Apex launched 150ft sections from the west bank and attached the pieces as they were launched.
