On April 5, 2021, Knife River will begin installing a new waterline and reconstructing 1st Street between Yellowstone Avenue and the 1st Street/Lomax Street junction.

Multiple lane closures and traffic configurations are necessary to complete the work. Motorists are encouraged to plan alternate routes.  The work is anticipated to be completed the end of August 2021, barring unforeseen issues.  

RELATED PRESS RELEASE | Nov. 23, 2020 | 1st Street waterline improvements resume next spring while plans to revitalize Northgate Mile and 1st Street corridors continue

The waterline project is a continuation of the 2019 project from the 1st Street/Lomax Street junction eastward to the Idaho Canal.  The project entails replacing the waterline, reconstructing the roadway to eliminate excessive crowning and extend its useful life, making storm drain improvements, replacing the island at the junction, and upgrading street lighting. 1st Street Lane Closures_Graphic

The multiple lane closures and traffic configurations include, but are not limited to: 

  • The eastbound lane of 1st Street, between Yellowstone Avenue and S. Holmes Avenue is anticipated to remain open for the entire duration of the project. 
  • Initially, the westbound lane of 1st Street, between S. Holmes Avenue and Yellowstone Avenue will be closed. 
  • After the westbound lane of 1st Street, between S. Holmes Avenue and Yellowstone Avenue is able to reopen, the westbound lane from the 1st Street/Lomax junction to S. Holmes Avenue will be closed as work progresses. 

Every effort will be made to accommodate access into businesses and residential properties, although some activities will temporarily block access due to the nature of the work.  

Please reduce speeds, obey posted traffic control signage, and watch for construction crews throughout the work zone.
