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.

 

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.

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: Idaho Transportation Department
Status: Ongoing

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.
