Ribbon Cutting Event - October 9, 2013
The new bridge was opened on October 1, 2013. A series of construction photos is posted on Flickr that shows progress on the bridge from dismantling of the old to completion of the new.
Project Description Completed in October 2013
Bridge #546, on Carter Road, spans Swamp Creek just north of the Snohomish—King County line in the Bothell area. Built in 1966, the old bridge was a two-lane, timber and concrete structure which had required increased maintenance prior to replacement in 2013.
The new bridge is longer and wider than the old. There is a 5.5-foot wide sidewalk on each side of the bridge, instead of the single, narrow sidewalk of the old bridge. Five-foot wide shoulders were added to the design to accommodate bicyclists. The longer bridge also spans the creek, eliminating the old center piers which collected debris during high water events. Invasive plants near the bridge were removed and will be replaced with native plants.
An environmental review of this project was completed, in compliance with the State Environmental Policy Act (SEPA). The SEPA documents can be reviewed below. For questions please contact: Mary Auld, 3000 Rockefeller M/S 607, Everett, WA 98201 or 425-388-3488 ext. 4510.
Construction contractor: Mowat Construction Company
Note: Seattle University engineering students used the bridge for a class project, were mentored by county staff, and won a 2009 NCEES Engineering Award for Connecting Professional Practice and Education.
