Three Cities River Crossing Study
Sponsor: Ada County Highway District
Status:
Open for Public Comment July 2010, end date TBD
The purpose of the study is to conduct environmental analysis and concept level engineering to define an alignment for a new road and bridge connecting the intersection of State Highway 55 and State Street on the north with Chinden Boulevard (U.S. 20/26) on the south. Currently the river crossings in this area are four miles apart. A new river crossing would relieve congestion on Glenwood Street and Eagle Road .
In August 2006, the ACHD Commission recommended Alternative 6 as the preferred alignment for federal highway officials to consider.
Traffic Management Center, Location, and Concept
Sponsors:
Idaho Transportation Department and various government entities
Status:
Completed December 2007
This study will identify a location and begin preliminary design work for a regional Traffic Management Center . Discussions are underway with other agencies regarding potential tenants.
Transportation and Land Use Integration Study
Sponsor: Ada County Highway District
Status:
Ongoing in 2009
ACHD is actively implementing the ideas brought forth through the Communities in Motion and Blueprint for Good Growth through the Transportation and Land Use Integration Plan. The Plan will create new roadway cross-sections for ACHD, a local transportation model, a new method for determining functional classification, a more thorough corridor preservation plan, and needs for land use and urban design changes and standards through the cities in Ada County.
Treasure Valley Air Quality Study
Sponsor: Idaho Department of Environmental Quality
Status:
Completed July 2010
The study developed meteorological profiles of pollution events, compile existing data into one database, validate and analyze the data, and use the data as an input to the CMAQ model to run scenarios that will enable DEQ to measure the effectiveness of control measures. The study will also develop an emissions inventory that will be used in the development of the PM 10 and CO Maintenance Plan updates.
Treasure Valley High Capacity Transit Study
Sponsor: COMPASS and Valley Regional Transit
Status:
Completed 2009
The Treasure Valley High Capacity Transit Study* consists of three related planning projects: downtown circulator to improve mobility in downtown Boise, downtown Boise multi-modal center, and high capacity corridor along I-84.

Treasure Valley Intelligent Transportation Systems (ITS) Strategic Plan
Sponsor: Ada County Highway District
Status:
Complete, adopted October 2006
The purpose of this report is to replace the 1999 Treasure Valley ITS Strategic Plan in its entirety. The plan defines the framework and specific deployments to most effectively implement the Treasure Valley ITS program through a cooperative effort by multiple agencies. The plan also provides an approach that leverages these deployments to maximize the benefits of systems integration and the utility of shared resources, particularly communications infrastructure.
ITS Strategic Plan
Treasure Valley Truck Freight Travel Study
Sponsor: COMPASS
Status: Completed April 2008
The purpose of this project is to collect data needed to analyze truck freight movements on major regional roadways. Data collected can then be used by COMPASS to develop more reliable through-trip and truck-trip tables for the travel demand model. This project will provide information on truck freight origin/destinations, type/weight of freight, and preferred travel routes in the six county Communities in Motion study area with emphasis on travel routes using congested interstates and principal arterials. It may also provide insight into trucking information.
Urban Interchange Concept
Sponsors: Ada County Highway District and the Idaho Transportation Department
Status: Not yet underway
This study will produce a concept for one of the urban interchanges included in COMPASS' Destination 2030 Limited Plan Update , the long-range transportation plan. An urban interchange is similar to freeway interchange in function, but is located at the intersection of two major non-interstate roadways ( Eagle Road and Fairview Avenue , for example). Urban interchanges require less right-of-way than a standard freeway interchange.
US 20/26 Corridor Plan
Sponsors: Idaho Transportation Department
Status:
Scheduled completion fall/winter 2011
This study will provide a corridor plan to identify current and future highway needs for more than 14 miles of U.S. 20/26 extending from I-84 near Caldwell to Nyssa, Oregon.
US 20/26 Corridor Preservation Study (Caldwell to Eagle Road)
Sponsors: COMPASS and the Idaho Transportation Department
Status:
Ongoing, expected project completion early 2011
The US 20/26 Corridor (Chinden Boulevard) has been experiencing high growth. The study area begins at Interstate 84 in Caldwell and ends at Eagle Road (SH 55). The US 20/26 Corridor Preservation Study will identify future transportation improvements and determine the need for future right-of-way between Boise and Caldwell. It includes areas within the cities of Boise, Eagle, Meridian, and Caldwell as well as unincorporated Ada and Canyon Counties.
When complete, the U.S. 20/26 Corridor Preservation Study will identify:
- A vision for how roadway should function as part of the regional transportation system.
- An Access Management Plan. (Completed in December 2008)
- The improvements and actions necessary for the vision to be implemented.
- Additional right-of-way needed to accommodate the future needs in the corridor.
US 95 Corridor Plan
Sponsor: Idaho Transportation Department
Status:
Expected completion in 2011
Study will deliver a corridor plan for US 95 from the Nevada State Line to District Three boundary north of New Meadows.
