19th Avenue | North Valley Parkway Bridge

North Valley Parkway is a major arterial parkway in Phoenix and Anthem, which varies from two to five lanes, divided and undivided, and includes bicycle lanes. This project constructed a grade-separated bridge crossing of the Central Arizona Project (CAP) and its maintenance roadways. The project also included paving and drainage improvements along North Valley Parkway (19th Avenue) extending from Jomax Road south of the CAP and meeting Quail Track Road north of the CAP. The project contained Geofoam backfill to protect an existing high-pressure waterline and was built between two influential neighborhoods. The project included constructing a bridge crossing, roadway embankment, artistic rustication bridge retaining walls, sidewalks, paving, curb and gutter, medians, storm drainage, improvements to CAP Operations and Maintenance roadways, landscape, and street lighting. Hunter provided a detailed girder erection plan engineered with detailed phasing diagrams to accommodate a critical no-load zone over a shallow 54-inch transmission main.
