The Blue Bridge (officially named the Pioneer Memorial Bridge) is a four-lane arch-truss bridge connecting Pasco, Washington to Kennewick, Washington. U.S. Route 395 crosses the Columbia River via this bridge. The name comes from the blue paint used on the truss superstructure, with white paint on the suspension beams. The bridge was painted green at time of construction (green being the state color of Washington). It is one of three bridges connecting Pasco to the other members of the Tri-Cities of Washington (Kennewick and Richland), along with the Cable Bridge to the east and the Interstate 182 Bridge from Richland to the northwest.
