The biggest challenge with this project was the setting. Needless to say, downtown streets in a city of more than 200,000 people tend to be busy at most hours of the day. As such, our crews didn’t have the option to shut down specific streets or infrastructure for long periods of time. Instead, we needed to keep street lights and traffic signals going throughout the day—and keep traffic flowing throughout those intersections—as we swapped out circuits and moved the lights over to the new system. COVID-19 added to the challenges, not only by causing delays in getting certain materials for the job, but also by adding COVID testing sites in Downtown Grand Rapids that limited our street-closing abilities further.
By using generators for temporary power, we were able to keep traffic signals and street lights running—and daily Grand Rapids traffic flowing—while we moved forward with the project. Our crews did need to work through several nights to complete final switchovers, since that was the only time we were able to completely shut down certain traffic signals and the roads that ran through them. Newly complete, the upgraded system, will provide greater traffic signal and street lighting reliability going forward – for the City of Grand Rapids and for every person or vehicle that travels its streets day in and day out.
