US-95: CDA signal upgrades
Upgrading signal technology will improve traffic flow and functionality in emergency situations.
Construction
Work will be done at night, with flaggers reducing US-95 to one lane in each direction. Crews will generally work at one intersection at time and usually for one week at a time.
More information will be released closer to construction.
Project details
Most signals on US-95 between Ironwood and SH-53 will be upgraded, except for those recently installed.
Upgrades in detection devices will help signals be more responsive. Backup batteries and other power sources in new cabinets will keep signals running even after losing power, and reflective backplates will be added to signals to improve visibility.
Pre-emption devices are being added to the corridor to improve EMS response time.
