Ebey Slough Bridge Marysville

Ebey Slough Bridge in Snohomish County is one of four bridges built between 1925 and 1927 to link Everett and Marysville and complete the last section of the Pacific Highway in Washington state. 

Upon their completion, motorists could for the first time drive on one road through Western Washington from the Oregon border in Clark County to the Canadian border in Whatcom County. 

The bridge crosses the northernmost of four waterways that have complicated travel between the two towns since the earliest days of white settlement. Because the slough is used by boats and barges, the Ebey Slough Bridge is a swing span that rotates on a mid-slough pivot to clear a channel for vessels. 

Although the completion in 1969 of Interstate 5 between Everett and Marysville made the old route less essential, it still carried a large number of vehicles. 

But the Ebey Slough Bridge was designed for a simpler time; it could accommodate only two lanes of traffic and one narrow pedestrian walkway. The bridge stopped opening for floating traffic in 2010, and in 2012 it is to be replaced by a modern, fixed-span, four-lane bridge.
