 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.In addition to the freeway expansion, WSDOT is considering a total replacement of the westbound Hewitt Avenue Trestle that would cost between $750 million to $1 billion.
