Ada County Highway District

State Street/Veterans Memorial Parkway/36th Street Intersection

Construction update as of 02/16/18:  The Preconstruction Meeting was held January 23rd. Tree removal and irrigation work started the week of January 8th. Crews are working on removals on the south side of the roadway to prepare for temporary paving. Utility relocations started in advance of construction and are on-going. Irrigation work is on-going.

As early as end of February/early March left hand turns directly from State St. will be removed. Left turns onto State St. will remain. Message boards will be placed at key locations two (2) weeks prior to the removal of the left turns to remind commuters of the upcoming change.

Upcoming Night Work: Sunday, February 19th to Thursday, February 22nd. Irrigation pipe crossings at 36th St., Anderson St., Mercer St., and Arthur St., will be done as night work. The expected impacts are as follows:

    • February 19th/20th: 36th Street- this road will not be completely closed but will have flaggers
    • February 21st: Anderson St.- this road will need to be closed where Anderson meets State. There will be signs posted to provide seven (7) day advance notice.
    • TBD: Mercer St- this road will not be fully closed but will have flaggers
    • TBD: Arthur St. – this road will not be fully closed but will have flaggers

On February 5th, work began to remove obstructions such as sidewalk, signs, etc. along the south side of State St. to make room for temporary paving. The temporary paving will allow traffic to shift to the south side of State St. while work is being completed on the north side. That traffic shift is expected to occur end of February/early March.

While obstructions are being removed pedestrian traffic will shift from the south side of State St. to the north side. Detour routes will be signed and will be at Willow Ln. and State St. (west side) and at Idaho Transportation Department (ITD) (east side). Also, the High-Intensity Activated crosswalk Beacon (HAWK or a Pedestrian Hybrid Beacon) located to the west of the State/VMP/36th intersection (just past Arthur St.) will be removed to provide space for the temporary paving needed for construction. This signal will remain down for the duration of the project (February to October). 

Construction to start!

The Ada County Highway District (ACHD) and Idaho Materials & Construction are rebuilding the intersection of State Street, Veterans Memorial Parkway and 36th Street. Utility work began in January and construction will start at the beginning of February. Work is expected to be complete in fall 2018.

What can neighbors & commuters expect?

  • Work is anticipated to occur between 7 a.m. and 7 p.m.  Night work and weekend work is expected.

State Street
Agencies throughout Ada County have been working since 2004 to develop a vision for the State Street corridor. State Street is envisioned as a transit corridor with increased regional, express and local bus service, and high occupancy vehicle (HOV) lanes. The future HOV lanes adopted by the State Street Plan will be dedicated for buses, multiple-occupant vehicles, and right-turning vehicles.

On March 27, 2013 the ACHD Commission voted to adopt the State Street/Veterans Memorial Parkway/36th Street Intersection Study concept report and preferred alternative #9 (Partial Median U-turn/ThrU-Turn).


The Ada County Highway District (ACHD) and the City of Boise are working together on a study of the State Street/Veterans Memorial Parkway/36thStreet intersection area, a neighborhood that features a popular park, an elementary school and a variety of businesses.

The goal of the study is to design an intersection that will efficiently and safely meet the future needs of all users - motorists, pedestrians, bicyclists and transit users.
