GRAND RAPIDS, Mich. (WOOD) — A problem at an electrical substation caused several traffic lights in Grand Rapids to go dark Monday morning.
The lights went back on around noon.
A city spokesperson said the problem, which began around 9:45 a.m., stemmed from two blown fuses at the Consumers Energy Coldbrook substation, in the area of Leonard Street and Monroe Avenue.
Consumers confirmed to News 8 the problem was caused by a squirrel getting into the equipment. It was killed.
The Coldbrook substation feeds traffic lights, parks, parking lots and other city-owned properties.
Guidance on how to handle a dark traffic light, which previously had been somewhat confusing, was clarified in Michigan in 2018 with a law that requires them to be treated as an all-way stop.
