Bridge Projects
Buck Creek Bridge – A prestressed concrete bridge built in 2007 provides access to three residences
on rural parcels near Horseshoe Lake, in Pend Oreille County. The bridge is 50’-span x 16’-wide deck with
galvanized steel guardrails. Bridge construction replaced an 8’-diameter culvert that was a fish passage barrier for kokanee salmon from Horseshoe Lake, and the under-sized culvert was also structurally failed.
Antoine Creek Bridge – A 35’-span x 14’-wide weathering steel bridge was built over Antoine Creek in 2016, for access to the house and farm buildings shown in background. Prior to bridge construction, this road occasionally washed away when an under-sized culvert was overtopped by spring snowmelt. This private property is near Havillah in Okanogan County.
Cherokee Creek Bridge – This 50’-span x 14’-wide weathering steel bridge replaced an inadequate multiple culvert installation for access to six rural residential properties near Oso, in Snohomish County. The bridge (built in 2012) meets requirements for emergency vehicle access, county code for vehicle live load, and provides fish passage for steelhead, coho salmon, and other native fish.
Chimacum Creek Bridge – A private rural property (farm) is accessible across this 40’-span x 14’-wide weathering steel bridge. Constructed in 2013, the bridge crosses an important chum salmon spawning stream (Chimacum Creek) near Center, in Jefferson County.
Coulee Creek Bridge – Multiple under-sized culverts that were repeatedly flushed downstream (along with buried utility services) were replaced with a 60’-span x 16’-wide weathering steel bridge in 2012. About eight private residences on rural parcels rely on this bridge for property access; Coulee Creek is in Spokane County about 15 miles northwest of the City of Spokane.
Decker Creek Bridge – Several private landowners rely on access provided by this 60’-span x 14’-wide weathering steel bridge. Interdisciplinary considerations included county code requirements including emergency vehicle access, fish passage, flood flow conveyance, WDFW & Tribe recommendations, and others. The bridge was built in 2018 about 5 miles west of Matlock, in Mason County.
Derby Creek Bridge – A 30’-span x 14’-wide (deck) weathering steel bridge provides access to a private rural property near Peshastin, in Chelan County.
Derby Creek Bridge – This weathering steel bridge (30’-span x 14’-wide) located on private land near Peshastin (Chelan County) provides access to multiple private parcels.
Eagle Creek Bridge – Several existing residences are accessed by this 40’-span x 14’-wide weathering steel bridge, which also carries electric and telecommunications services across Eagle Creek. These private properties are about 5 miles northeast of Leavenworth, in Chelan County.
Field Creek Bridge – In 2014, this 50’-span x 14’-wide (driving surface) weathering steel bridge was built over Field Creek about 2 miles west of Joyce, in Clallam County. Residents of six homes and adjacent properties use this bridge, and the bridge also carries water and telephone utilities over the creek valley.
Field Creek Tributary Bridge – Weathering steel guardrails show the location of a 40’-span x 14’-wide weathering steel bridge over a tributary to Field Creek near Joyce (Clallam County). This modular bridge set on pre-cast reinforced concrete footings was built in 2009.
Huge Creek Bridge – Two private owners (residences) needed replacement of a dilapidated RR car bridge spanning Huge Creek, and this 60’-span x 16’-wide weathering steel bridge was built in 2006. Huge Creek is about 5 miles west of Purdy, in Pierce County.
Lackamas Creek Bridge – This 40’-span x 14’-wide weathering steel bridge was constructed summer 2009 for access to two residences and other private parcels, over Lackamas Creek. This salmon stream is in Thurston County about 8 miles southeast of Yelm.
Little Spokane River Bridge – Access to multiple private parcels over the spring-fed Little Spokane River is provided with this 50’-span x 16’-wide prestressed concrete bridge with galvanized steel guardrails. Bridge location is about 5 miles southwest of Newport in Pend Oreille County; built in summer 2007.
Manastash Creek Bridge – Residence and farm access is provided with this 60’-span x 16’-wide weathering steel bridge, with sufficient freeboard under bridge beams for flood flow conveyance (and passage of large wood) for Manastash Creek. Construction occurred in 2019; the site is about 5 miles west of Ellensburg in Kittitas County.
Minter Creek Bridge – A 30’-span x 14’-wide steel bridge (painted) crosses Minter Creek for access to a farm and residence in Pierce County, near Vaughn. Bridge construction in 2005 followed regulatory review and approval by the county, WDFW, and Puyallup Tribe of Indians.
Pataha Creek Bridge – A large (failed) culvert along Pataha Creek was replaced with a 40’-span x 22’-wide prestressed concrete bridge in 2008. This bridge provides access to one rural residence and substantial private timberland; bridge location is about 10 miles south of Pomeroy in Garfield County.
Purdy Creek Bridge – A private forested parcel (and residence) are accessible via this 40’-span x 14’-wide weathering steel bridge built in 2011 near Purdy, in Pierce County. The bridge meets all requirements for emergency vehicle access (i.e. county code), flood flow conveyance, fish passage, and would support any vehicle load that would be allowed on state highways.
Sandy Creek Bridge – A problematic and under-sized culvert along a private road was replaced with this 40’-span x 14’-wide weathering steel bridge in 2014. Several residences and private parcels rely on this bridge for access and it has performed well over multiple peak flow events. Sandy Creek is about 5 miles south of Mount Vernon in Skagit County.
South Fork Clugston Creek Bridge – A hazardous wood plank bridge was replaced with this 30’-span x 14’-wide weathering steel bridge in summer 2016. This stream crossing provides access to one residence and private timberland about 10 miles north of Colville, in Stevens County.
Starbird Creek Bridge – Six residences have access over Starbird Creek via this 50’-span x 16’-wide weathering steel bridge with asphalt driving surface. Bridge construction in 2014 replaced several small culverts that overtopped during high flow events, and posed a barrier to salmon in Starbird Creek. Starbird Creek is about 8 miles south of Mount Vernon, in Skagit County.
West Side Canal Bridge – A 15-acre private parcel near Ellensburg (Kittitas County) required crossing West Side Canal for residence construction. This 30’-span x 16’-wide weathering steel bridge constructed in 2020 met all requirements by Kittitas County, WDFW, WDOE, and the West Side Canal Company.
