HELENA, Mont. — Starting this week, the City will begin a three-week project to install a water main between West Main St. and the Reeder’s Village subdivision. This is part of a larger project that includes the replacement of a main between Eureka well and Hale water storage tank, and the addition of a main between Hale and the water distribution system on West Main St. The existing Eureka Well pipe is 130 years old. Updating and replacing the piping will improve the operations, reliability, and resilience of the City’s water supply system. The addition of a dedicated outlet from Hale tank for West Main Street will provide much needed water for fire suppression and provide water service in times of power outage on Main St.
This project will require the temporary closure of the lower section of Carriage Lane, requiring traffic in the Reeder’s Village neighborhood to reroute using Howie St. for ingress and Adams St. for egress. Traffic flow signage will be posted throughout the neighborhood and along the detour route. Emergency services access will remain available. Staff do not anticipate water service interruptions to homes in the area. Though the Mount Helena Trailhead will remain open during construction, city trail users are encouraged to access Mt. Helena City Park via Dump Gulch, Tubbs, or Le Grand Cannon Trailheads to ease traffic congestion.
The larger West Main/Eureka to Hale project has an anticipated completion timeline of July 2026. The City of Helena has contracted with Mike Coleman Construction, Inc. to complete this project.
