Lower Rattlesnake water main project begins April 29, affects Missoula traffic routes

MISSOULA, Mont. - The City’s Public Works and Mobility Department will begin a water main replacement project on Monroe, Jackson, and Vine streets in the Lower Rattlesnake Neighborhood on April 29, 2024, with completion expected August 5, weather dependent. 

The following is a news release from Missoula Public Works.

MISSOULA, Mont. - The City’s Public Works and Mobility Department will begin a water main replacement project on Monroe, Jackson, and Vine streets in the Lower Rattlesnake Neighborhood on April 29, 2024, with completion expected August 5, weather dependent. 

It’s important to note that this project will affect both Lower and Upper Rattlesnake Neighborhood residents and others who use Monroe St. as a cut-through route to Van Buren St. when trains block Madison St./Greenough Dr. traffic into downtown. When Monroe St. is closed during construction, traffic will be detoured to Lolo St. and over to Rattlesnake Dr. to Van Buren St. Detour and additional signage will be posted around the work area. Local access to homes in the construction area will be maintained during construction.

For more project information and detour maps, visit www.ci.missoula.mt.us/2668/Water-Projects. This web page will be updated as necessary during construction.

The City’s water utility continues to improve the municipal water system with this project, replacing approximately 1,750 lineal feet of 6-inch Kalamein pipe and 2-inch invasion steel water main that was installed in 1914. The main is in poor condition and has been identified as leaking. 

Replacing these segments of pipe will reduce water leakage and improve water service reliability. In addition, replacing old, leaking water main pipe reduces the water utility’s energy usage and related costs because the pumps that move water through the system will not need to operate continuously to pump water that leaks from the system before reaching customers.
