Project Description

Project consists of construction a new traffic signal system to accommodate a new right-turn lane for added turning capacity for west-bound traffic turning northbound onto Columbia Center Blvd. In addition, the proposed work will require the installation of a roundabout at Colorado St. and Deschutes Ave. The proposed work includes the installation of curb, gutter, sidewalk, traffic curbing, concrete traffic islands, retaining walls, driveways, storm drainage, utility trench excavation, landscape and irrigation restoration, HMA patching and overlay, striping, signage and a new signal system. Along Deschutes Ave the entire intersection at Columbia Center Blvd and at Colorado St. will be overlaid with hot mix asphalt and restriped. This proposed work will be in preparation to widen Columbia Center Blvd north of Deschutes Ave, adding a 3rd lane for northbound and southbound through traffic on Columbia Center Blvd to Quinault Ave.
