Remembering the Ebey Slough Swing Bridge

The Ebey Slough Bridge served Snohomish County, Washington, for 85 years before being replaced in 2012. It was a unique swing bridge design and was one of only four swing bridges left under WSDOT care. Down from 16 in 1944, there are only three swing bridges left at WSDOT now, and the Ebey Slough Bridge was a great example of a bridge type that may not be around on state highways much longer.

WSDOT's recent and updated listing of bridges, 12/16/11, that may or not be historic in the State of Washington as kept by the semi-retired Craig Holstine has this bridge as now "determined eligible" for the NRHP. But no worries WSDOT plans to demolish it in a few months when the new bridge opens, the new being exactly one foot higher than the old one and fixed to eliminate those pesky openings.

From sea to shining sea... a torrent of pointless wasteful historic bridge demolition. Is WSDOT simply trying to keep up with New York City DOT?
