GREAT FALLS – A dump truck hit a transmission line Monday, cutting power for just over half an hour to thousands of residents across central Montana.
NorthWestern Energy says the truck hit a transmission line just before 8 a.m. near Rainbow Dam in Great Falls. That affected six substations, cutting off power to more than 15,000 customers in Great Falls, Ulm, Mission, Cascade, Wolf Creek and Craig.
In Great Falls traffic signals were out, C.M. Russell High School lost power, some radio stations were knocked off the air and many residential and business customers were affected.
NorthWestern Energy says power was back online within 35 minutes.
