Ada County Highway District

Columbus Street, Overland Road to Kootenai Street

Update as of 8/19/19:

Columbus is closed between Overland and Kootenai. Crews working on placement of base gravels and prepping for curb, gutter, and sidewalk. Concrete work is scheduled to start the week of August 19th.

Utility relocations are ongoing.

There was a preconstruction conference on February 8th.

Originally, this project was to be constructed during the spring/summer of 2018. Unfortunately, the bids we received for construction were not satisfactory. As a result, the project went back out to bid the fall of 2018 and construction is set to begin late February 2019.


General Description:

  • Construct curb, gutter and sidewalk on both sides of Columbus Street.
  • Maintain on-street parking on both sides of the street.
  • Rebuild the roadway.
  • Sharrows (shared lane markings) will be painted on the street after the rebuild.
  • View the project design under "Related Documents" to the right of your screen.
