Future construction of roadways and improvements to the infrastructure of Ada County's
transportation system are planned in advance in order to best serve the public needs
as growth in the county continues to expand.
The Community Planning Association of Southwest Idaho (COMPASS) is the agency that
is charged with developing the Long Range Transportation Plan currently titled Communities in Motion.
Transportation activities cover the realm of demographic projections to twenty-year
long range plans and creating a vision for the future transportation system in Ada
and Canyon Counties.
Once a project is in the Destination 2025 Long Range Transportation Plan for Ada
County, the ACHD prioritizes these projects and others not shown in Destination
2025 based on the immediate and projected needs of the road system and on input
from the citizens of the county that use these roadways. These projects are then
placed in the ACHD Integrated Five-Year Work Plan document. This programming document is approved annually by the ACHD Board of Commissioners.
It is the basis for future planning but may change subject to specific project approval
for each budget year.
Other projects can be found in the COMPASS Transportation Improvement Plan (TIP). These projects are regional in scope and/or funded with federal aid and include projects constructed by the Idaho Department of Transportation.
