This project is substantially closed. 

  • Construct curb, gutter and sidewalk on east side of Phillippi Street between Targee Street and Overland Road.
  • Rebuild the street
  • Rebuild existing speed humps
  • Add sharrows (shared lane markings) to designate a shared travel lane for both bicyclists and motorists.
  • Construct bulb outs and update pedestrian ramps
  • Improve stormwater facilities

Commuters are reminded to obey all road closure signs and follow the signs along the detour route. Commuters should never attempt to drive, bike, or walk on closed portions of the road, regardless of whether there appears to be active construction. It is unlawful to move or manipulate construction signs and doing so can put commuters and construction workers at great risk.

    ACHD has indefinitely paused ongoing work on the pedestrian signal crossing located at the intersection of Philippi and Overland Roads.

    December 3, 2021 Update: ACHD has indefinitely paused ongoing work on the pedestrian signal crossing located at the intersection of Philippi and Overland Roads. During construction, our project team encountered issues that pose constraints for the planned improvements. With the current design, the contractor is unable to complete the project to standards. As a result, the project will be on hold until ACHD can determine if and when it can progress safely and meet the high standards we value as an agency. Commuters will find that the roadway is now re-opened. Work was started to make pedestrian ramp improvements and ACHD is working to ensure the facilities pose no safety issues for pedestrians during this intermission. We appreciate the community's ongoing patience while we determine the future of this project.

    A petroleum pipeline, owned by Marathon Pipe Line (MPL), runs along both sides of Phillippi Street. As a result, ACHD has been working closely with MPL throughout the project development and has continued to do so to ensure that the highest safety standards are being maintained during construction. These safety standards include the Federal Pipeline Safety Standards adopted at 49 C.F.R. Part 195 and include regulations relating to design requirements, construction, pressure testing, operation, and maintenance (including maximum operating pressure, valve maintenance, pipeline repairs, pipe movement, over pressure safety devices, public awareness, damage prevention, and leak detection), qualification of pipeline personnel, and corrosion control. In addition, Idaho has established underground facility damage protection standards and requirements at Title 55, Chapter 22 to ensure any excavation is done safely and carefully, and with knowledge of the location of underground facilities such as the Marathon pipeline.

    Additional steps being taken to ensure neighborhood safety:

    • When our contractor, Knife River, is working within 50 feet of the pipelines a MPL representative will be on-site.
    • An ACHD inspector will be on-site on a regular basis.
    • ACHD and Knife River have taken significant efforts to determine the pipeline location.
    • MPL authorized equipment will be used when compaction is required over the pipelines.
    • MPL monitors and controls the pipeline network 24 hours a day, 7 days a week. Pressure changes would trigger an immediate alarm at their operations center.
    • Both pipelines are outfitted with valves that can be shut down remotely.
    • MPL has an established Emergency Response Plan, which includes working with local emergency responders and maintaining the proper equipment to address different situations.
