Five Year Work Plan

Nampa Highway District publishes a fiscally constrained Five-Year Work Plan, which it updates annually. The principal types of projects listed in the plan are seal coats, overlays, rebuilds, and new construction. It does not show smaller projects, such as ditch cleaning, culvert replacement, sign replacement, crack sealing, or emergent repairs.


Roadway projects are designed to improve safety and to improve traffic flow. Roadway projects may include seal coat, overlay, rebuild and new construction.


Traffic Studies are designed to improve safety and traffic flow in addition to future planning for transportation projects throughout the Nampa Highway District.


Stormwater is inclement weather water that flows over the ground and does not soak into the soil. For more information and to report stormwater issues, see stormwater tab.

Intersection project

Intersection projects are designed to improve traffic flow and public safety. They range from a full intersection redesign and rebuild to the addition of traffic signals.


Nampa Highway District is responsible for bridges and culverts within the district. Regular inspections are performed to monitor for wear and to ensure we meet or exceed all State and Federal Standards.
