The Arizona Department of Transportation (ADOT) is preparing to convert freeway lighting in the Maricopa County region from the existing High Pressure Sodium (HPS) lighting to state-of-the-art Light-Emitting Diodes (LED) lighting. This work will be implemented through a Design-Build-Finance-Operate-Maintain Pubic Private Partnership (P3) agreement.
The project seeks to upgrade approximately 19,000 luminaires to LED technology with remote monitoring and controls, covering approximately 300 miles of controlled-access highways throughout the Maricopa County region (ADOT Central District), including the Deck Park Tunnel on Interstate 10.
Benefits of this project include enhanced visibility and cost savings. Studies have found the whiter light common to LED roadway lighting may result in better driver reaction times and improved visibility. Because of the longer life of LED lights, there is less maintenance and fewer crews working along the freeways, which promote both safety and cost savings. This project will also reduce ADOT’s energy consumption and costs across the Maricopa County region.
The Request for Qualifications has been released. The responses are due in late September 2017, and a short list of proposers is scheduled to be determined in early November 2017. A Draft Request for Proposals (RFP) is scheduled to be provided to the short-listed proposers in December 2017. A final Request for Proposals will be provided to short-listed proposers in the spring of 2018, with an award expected by June of 2018
