State Street Transit and Traffic Operational Plan




   State Street is the only Treasure Valley roadway that connects the communities of Star, Eagle and Boise. As the population of the Treasure Valley grows, State Street will require improvements to accommodate increased traffic along the corridor.
   This project identified and prioritized specific transit and traffic improvements that will develop State Street into a premier transit corridor in the Treasure Valley. This 15-month study built upon the transit vision established during the 2002-2004 State Street Corridor Strategic Plan.  That plan concluded that the most effective strategy for future transit would be to plan dedicated lanes that could accommodate high capacity transit operations, such a high-speed bus or light rail system. The study also found that implementing a high capacity transit system would require more than enhancing transit and traffic conditions; for this strategy to be successful, future development along State Street must be planned to support high capacity transit.
After completion of the above plan, a memorandum of understanding was developed and agreed upon by the partnering agencies to identify the roles and responsibilities of each agency in implementing this vision.
As part of this implementation, the State Street Corridor Market Strategy and State Street Transit Oriented Development Guidelines were completed to assist with identifying the market perspective on State Street and the guidelines for transforming State Street into a regional transit priority corridor. The State Street Alignment and Right-of-Way study is currently ongoing project by ACHD to locate the preferred centerline of the proposed seven-lane section and identify the needed right-of-way on State Street from Glenwood Street to 23rd Street.


The State Street Transit and Traffic Operational Plan (TTOP) makes recommendations regarding:

  • Traffic and transit improvements between downtown Boise and State Highway 16
  • Land uses and how they might develop
  • Alternate routes through Eagle and to downtown Boise
  • An implementation plan and financial strategy for the identified improvements

Winter 2009/2010

  • Review existing plans and studies of the State Street area.
  • Collect traffic data and analyze current traffic conditions.
  • Develop criteria that will be used to evaluate transit, traffic, and land use improvements.
  • Conduct interviews with State Street stakeholders.
  • Develop year 2035 future traffic conditions using the COMPASS regional travel demand model.

 A project team of transportation advisors will analyze current State Street transit and traffic conditions. The project team includes Ada County Highway District, Valley Regional Transit, City of Boise and State Street Studies Coordinator. The team will propose ideas and strategies for future improvements.


Spring 2010

  • Community Advisory Committee Meeting #1
  • Technical Advisory Committee Meeting #1
  • Develop a transit service plan
  • Conduct a traffic analysis to evaluate the transit and traffic alternatives between SH 16 and Downtown Boise Multimodal Center.
  • Identify and evaluate ITS improvements for the corridor.

A community advisory committee will be formed to give input and determine improvements that will best reflect the interests of stakeholders and communities along State Street. The committee will include key community members that have valuable experience and knowledge for developing a successful plan to improve transit and traffic along State Street.


Summer 2010

  •  Community Advisory Committee Meeting #2 

  •  Technical Advisory Committee Meeting #2

  •  Public meeting

 A public meeting will be held to present outcomes of the first two Community Advisory Committee meetings. At this meeting the public will have the opportunity to review and comment on proposed plan for improving transitand traffic along State Street. The public will also be able to submit comments throughout the process on the project website.


Fall 2010

  • Develop an implementation plan with phasing and financial strategy for the next 20 years. 
  • Community Advisory Committee Meeting #3
  • Technical Advisory Committee Meeting #3

 Proposed improvements and transit plans will be evaluated in a future alternatives analysis.

The resources below will help you learn more about the State Street Transit and Traffic Operational Plan:

  • State Street Corridor Strategic Plan – Completed in 2004. Established vision for the corridor and implementation strategy for making the vision a reality.
  • State Street MOU - Completed in 2005. A formal agreement signed by the agencies that that identifies the roles and responsibilities for the implementation strategy.
  • State Street Alignment/ROW Study – Ongoing project by ACHD, establish potential ROW footprint between Glenwood and 23rd.
  • State Street Corridor Market Strategy – Completed in 2007.  This study examined State Street from a market perspective, investigating redevelopment opportunities into nodes, or centers of development, with a focus on transit-oriented development (TOD). It is in support of a larger effort studying options to mitigate future traffic congestion and assist redevelopment along the State Street Corridor.
  • State Street TOD Guidelines – Completed in 2008, these policy guidelines are the first implementation step in a twenty-year project to transform State Street into a regional transit priority corridor. The Guidelines are intended to provide policy makers, planners, developers and interested citizens with an understanding of and direction toward transit oriented development (TOD) in the State Street Corridor.
