Integrated Five Year Work Plan 2021 - 2025

This is the seventh year of ACHD's Integrated Five-Year Work Plan. The 2021-2025 plan was adopted, by a unanimous vote, by the ACHD Commission on September 23, 2020.

This year the plan incorporates nearly $974 million in building, maintenance and operations, and enhancement of Ada County's nearly 5,200 lane miles of roadway infrastructure. The plan outlines the concept, design, right-of-way and construction years for some 409 projects and programs. Projects are included in the plan as a result of community input, as well as safety, scheduling and a number of technical factors.
