The Jackknife Bridge at Ebey Slough
1914 - 1980
Jackknife Bridge being raised over Ebey Slough, c. 1914.A Bridge with a Past.
This historic “Jackknife Bridge” was built in 1914, spanning Ebey Slough, giving access to the rich farmland of the Snohomish River delta and raising for river traffic. After many years of use it was listed on the National Historic Register as one of the few remaining bascule bridges.
How it was Raised.
A Bascule Bridge is counter-balanced; when the weight is lowered, the bridge deck rises. (“Bascule” is French for “weighing scales”.) The counter-balance was configured to fold toward the deck when rising, as a jackknife, hence the unique name.
Jackknife Bridge Retired.
In the 1950's, a new, wider span was built on Ebey Slough beside the Jackknife Bridge. The old bridge remained in place until removed by a local boat yard owner. He dismantled the rusted counter-balance apparatus and floated the bridge to his yard in Everett for salvage.
