Construction is Underway!
The Ada County Highway District (ACHD) and Concrete Placing Company are rebuilding the intersection of State Street and Collister Drive. Utility work began at the end of September and will continue with canal work beginning in mid-October. Construction will start in November. Crews will also be working on the bridge just west of the intersection.
What can neighbors & commuters expect?
Working closely with the public since 2004, agencies throughout Ada County have been developing and building out a vision for the State Street corridor. State Street's planned improvements include widening the roadway to improve traffic flow, adding a lane dedicated to carpools, vanpools, and buses and also improving biking and pedestrian infrastructure. This collaborative approach will bring communities closer together by increasing mobility options to benefit everyone.
Project Update September 2016
Noise Study & Sound Wall
A study completed as part of the project shows traffic noise in the project area currently exceeds state and federal noise policy standards in some locations and is expected to increase as traffic increases over the next 20 years. The study concluded that a sound wall on the south side of State Street will reduce noise impacts to the Edgewater Apartments. ACHD worked closely with the owners of the apartments and came to an agreement to build the sound wall as part of the project.
The agreement allows ACHD to move forward with the following schedule:

State and Collister Intersection Open House & Public Hearing
The Ada County Highway District (ACHD) is seeking comments on the new intersection design for State Street and Collister Drive. The design, based on the Alignment 1- Realignment concept approved by the ACHD Commission in November 2014, includes safety improvements at the intersection for those that bicycle, walk, drive and use transit.
Community input is important! Residents are encouraged to attend the meeting, view the design and provide comments. Attendees will have the option of providing oral testimony to a hearing officer on a one-on-one basis or submitting written comments.
*Adams Street between 40th and 38th streets may be closed for construction. Please use 37th Street off of Chinden Boulevard to access Adams Street.
On November 12, 2014 the ACHD Commission approved Alignment 1 - Realignment with the following Commission-directed actions for possible inclusion as the design develops:
Opportunity for Public Input: State and Collister to be presented to ACHD Commission Nov. 12
ACHD Commission Meeting
Wednesday, November 12, 2014 | Noon
ACHD Auditorium | 3775 Adams St., Garden City
At the October 22nd Commission meeting, the ACHD Commission asked staff to meet with stakeholders to consider more input on the 's recommended realignment of the intersection as the preferred alternative. Two workshops were held with stakeholders to discuss issues and brainstorm suggestions and potential revisions to the realignment alternative.
As a result, the State and Collister Intersection Project will again be presented to the Ada County Highway District (ACHD) Commissioners on Wednesday, November 12th at noon for a decision on which alignment option to adopt. Taking into consideration public opinion, long-range transportation plans, capital investment, property/business access impacts, and the best and safest alternative for all users of the roadway, ACHD staff will recommend Alignment 1 - Realignment to the Commissioners.
The Commission meeting will begin at noon; however, this project is one of several agenda items and may not be the first item discussed. ACHD staff will make a brief presentation, including a summary of what was heard from the stakeholders, followed by an opportunity for public comment before the Commission takes action.
