SR 532 continues across the wetland and crosses the main arm of the Stillaguamish River on the Camano Gateway Bridge at the west end of Stanwood.

[1] From downtown Stanwood, the road passes through the city's suburban hilltop neighborhoods, including a business district centered at 72nd Avenue Northwest.

[4] Stanwood and Camano Island were originally connected by a horse-pulled cable ferry on the Stillaguamish River, which was replaced by a steel swing bridge that opened on August 7, 1909.

[12][13] At the request of the three communities, the state government allocated $615,000 in funds (equivalent to $6.24 million in 2023 dollars)[14] to construct a new bridge over both the Stillaguamish River and Davis Slough.

[15] The new concrete bridge over the Stillaguamish River was opened on July 23, 1950, and named for World War II general Mark Wayne Clark, who resided seasonally on Camano Island.

[21] The Nickel gas tax program approved by the state legislature in 2005 included $84 million to fund a series of expansion and replacement projects along SR 532.

[23] A replacement for the Davis Slough Bridge began construction in August 2014 and was completed in May 2016, costing $29.3 million and funded with state gas taxes.
