Evans Construction is building a new sidewalk on the north side of Hansen Ave from Cache to Redmond Streets this week. Work will include installing sidewalk along Hansen from King to Willow and excavate along Hansen from Willow to Gros Ventre Streets. During this time, the street will be closed to west bound traffic but open to east bound traffic. The intersection at Willow may be closed for a ½-day for buried power crossing but will remain open otherwise. When closed, motorists are advised to use Kelly or Simpson as alternate routes.
