Construction Update April 9, 2021: Roadway excavation started on March 15th. Storm drain pipe installation from Targee to Overland has begun. There is ongoing utility and irrigation work.
Roadway excavation on Phillippi, Malad to Targee is ongoing.
There was a preconstruction meeting on January 14th. Idaho Power began relocations on February 8th.
Starting in early February, the Ada County Highway District will begin construction on the Phillippi Street Pedestrian Projects between Malad Street and Overland Road. Tree removal and trimming started in advance of construction to allow for Idaho Power pole relocations. Construction is anticipated to be complete late summer 2021.

Marathon Pipe Line and Safety
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:

History
In spring 2018 we learned that the original Phillippi Street design, with sidewalks on both sides of Phillippi, would cause significant impacts to the Marathon (formally Andeavor) petroleum pipelines located on the east and west sides of the street. This design would have required the pipelines to be relocated, an extremely costly endeavor that would cause a hardship to the residents of Phillippi Street during construction.
As a result, the District revisited the original design and assessed the alternatives to meet the purpose and need of this project - to increase connectivity for pedestrian and cyclists - while minimizing the impacts to the pipeline.
