Construction work on the two Lovell-to-Yellowtail transmission lines, which run between Lovell, Wyo., and Yellowtail Dam, Mont., continues to progress according to schedule.
The dual 94-mile, 115-kilovolt lines that carry power from Yellowtail Dam in Montana are undergoing a badly needed rebuild as many of their components can trace their origins to their construction in 1956 and 1966 by the Bureau of Reclamation.
“Many of the existing poles are in immediate need of replacement,” said Rocky Mountain Project Manager Travis Anderson.
The project is in the middle of the second phase, which includes rebuilding about 16 miles of each line that run both north and south of the National Park Service Big Horn National Recreation Area and Crow Reservation. Read more »

Contractors continue rebuilding two 115-kilovolt transmission lines as part of Phase II of the Lovell-to-Yellowtail project. With work in the Big Horn Canyon National Recreation Area complete in fall 2012, the construction contractor started removing the No. 2 line south of the NRA in Wyoming, March 25, 2013.
Crews have about 10 miles of the No. 2 line down and are working on setting new structures in cultivated fields before irrigation of farm land begins.
While crews work on the No. 2 line, the Lovell-to-Yellowtail No. 1 transmission line continues to deliver power from Yellowtail Dam.
The upgrades to the Lovell-to-Yellowtail transmission lines No. 1 and 2 are needed to replace the original lines built by the Bureau of Reclamation in 1956 and 1966.

When you think of Wyoming and Montana in the winter, you might think “cold”—cold enough that you wouldn’t want to be outdoors working on the construction of a transmission line. But that’s exactly what Western crews will be doing this winter.

Crews recently wrapped up rebuilding the Lovell-to Yellowtail No. 1 and No. 2 115-kilovolt transmission lines in the Big Horn Canyon National Recreation Area in Wyoming and Montana. They expect to begin reclamation of unneeded access roads soon. In Feb. 2013, they will begin rebuilding the sections of the lines north and south of the NRA.
The Lovell-to-Yellowtail transmission lines are located between Lovell, Wyo., and Yellowtail Dam, Mont., and help provide the reliable transmission of Yellowtail Dam’s generation.
