Barn Creek Road near Madison Dam temporarily closing for construction traffic

Nov 18, 2019

Butte, Mont. – Barn Creek Road in Madison County will be closed from Trail Creek trailhead to the Madison Dam powerhouse from 7 a.m. Monday, Nov. 18 to 5:30 p.m. Friday, Nov. 22 and again from 7 a.m. Monday, Nov. 25 to 5:30 p.m. Wednesday, Nov. 27.

The closure is due to a large NorthWestern Energy construction project that requires a significant number of large construction truck and trailers using the road during the closure times.

The public is cautioned to be aware of the heavy truck traffic upstream of the Trail Creek trailhead during the Barn Creek Road closure as well.

The project is an upgrade to the turbine-generators in the Madison Dam powerhouse that will increase efficiency and is also more fish-friendly.  The project will continue into early 2021, but additional road impacts are expected to be short-term with subsequent notifications.  NorthWestern Energy and our contractors will adjust the road and access considerations during the project to ensure safety while striving to maintain access for the public.

NorthWestern Energy appreciate the public’s patience and cooperation during this construction project. Questions can be directed to NorthWestern Energy Engineer B.J. Cope, 406-497-3418.
