 The study suggested the expansion of the limited-access highway from Snohomish to the western city limits of Monroe to four lanes, including an interchange at Bickford Avenue that was later completed in September 2013.A wider median with rumble strips was added to some sections of US 2 between Snohomish and Monroe in 2019.WSDOT plans to move US 2 onto a northern bypass of Monroe, which would avoid the business district and intersect SR 522 with a roundabout.
