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. From Monroe to Gold Bar, US 2 would be expanded to a four-lane highway, with a roundabout connecting the highway to the city of Gold Bar, and become a two-lane highway with wider shoulder lanes to Skykomish. Seasonal traffic congestion in the Sultan area, which causes backups that overflow onto side streets, have inspired proposals to build an additional bypass, a two-street couplet, or a freeway along the Stevens Pass corridor.
