Construction Process and Schedule
Before the PLA started its work, approximately 40 percent of the old street lights were not in operation due to burned out bulbs, deteriorated infrastructure, or theft of copper.
The PLA’s goal was to complete relighting all neighborhood and collector streets in Detroit by the end of 2015 and all major thoroughfares by the end of 2016. With that mission accomplished, there are now 65,000 new LED street lights in Detroit.
The work had three phases:
- Survey to determine the location, condition and type of light for every exiting street light.
- Design engineering work on the new system factoring in the location and condition of each light.
- Construction and installation of the lights on a ZIP code by ZIP code schedule
The new lights in neighborhoods are 150-watt equivalent LED lights, twice as bright as the 75-watt equivalent High Pressure Sodium lights that were standard under the old system. The LED lights are also much more energy efficient than the High Pressure Sodium lights.
The second priority was relighting the collector streets. Collector streets are the direct connections between residences and destinations such as community centers, schools, businesses and major roads. Some examples of collector streets include Grand Boulevard, Livernois, Mack Avenue, Seven Mile, Van Dyke, and Warren Avenue.
Representing the PLA’s third area of focus were the major thoroughfares. They are:
- Fort Street
- Grand River Avenue
- Gratiot Avenue
- Jefferson Avenue
- Michigan Avenue
- Telegraph Road
- Woodward Avenue
These streets received 400-watt equivalent lights. Work on them was completed in 2016.
