Central Phoenix/East Valley Light Rail Transit
As Prime Consultant, DEA was responsible for the design and PS&E for a $55 million, 3-mile segment of the Central Phoenix/East Valley Light Rail Transit Project. Line Section 2 began on Camelback Avenue, turned south onto Central Avenue, and ran for approximately 3-miles thru this major downtown corridor to McDowell Road. All rail designs conformed with Metro Rail design guides and specifications while all roadway and utility improvements complied with City of Phoenix and Maricopa Association of Governments Standards and Specifications.
Rail features included northbound and southbound embedded tracks within a 28-foot track guideway, raised guideway curbs and drainage systems, overhead contact system, control systems ductbanks, cathodic protections systems, and six stations.
The Central Avenue arterial roadway redesign features included: new rights-of-way, widening to accommodate the rail guideway located in the middle of the street, a roadway/rail bridge and two pedestrian bridges over SRP's Arizona Canal, new curbs and decorative sidewalks with special landscape and street/pedestrian lighting amenities, intersection redesigns, private property improvement reconfigurations and betterments, storm drainage systems, water and sewer relocations, irrigation systems, traffic signalization, signing and marking plans, and maintenance of traffic plans. In addition to engineering plans, specifications, and estimates; DEA provided design surveys using conventional survey techniques and thru the use of Cyrax (Leica HDS 2500) equipment which uses 3D Laser Scanning technology (High Definition Surveying, HDS) to generate a three-dimensional model of the field conditions.
