The Canyon County Board of Commissioners voted unanimously Tuesday to approve a $28 million road improvement budget for fiscal year 2027, the largest single-year investment in county road infrastructure in over a decade. The funding will target deteriorating rural roads, intersection safety upgrades, and bridge maintenance across the county’s 1,400-mile road network that serves the growing communities of Nampa, Caldwell, Middleton, and surrounding areas.
The budget increase represents a 35% jump over the current year’s $20.7 million road allocation, funded primarily through increased highway user revenue distributions from the state and impact fees collected from new residential and commercial development across Canyon County. No property tax increase is required to fund the expansion.
Where the Road Money Will Be Spent in Canyon County
Commissioner Leslie Van Beek, who chairs the county’s infrastructure committee, outlined the spending priorities during Tuesday’s public hearing at the Canyon County Courthouse in Caldwell. The largest allocation — $12 million — will fund reconstruction of approximately 15 miles of rural roads in the rapidly growing areas between Nampa and Star, where residential subdivisions have added thousands of daily vehicle trips to roads originally designed for agricultural traffic.
An additional $8 million will fund intersection safety improvements at 12 locations identified as high-accident corridors in the county’s most recent traffic safety study. Priority intersections include the Middleton Road-Ustick Road junction, the Lake Lowell Avenue-12th Avenue South intersection in Nampa, and several crossings along the Caldwell-Nampa corridor where commuter traffic has outpaced road capacity.
“Canyon County’s roads are carrying traffic loads they were never designed for,” Van Beek said during the hearing. “Every new subdivision that goes in adds hundreds of daily trips to roads that haven’t been upgraded in 20 or 30 years. This budget starts to close that gap, and it does it without raising property taxes on Canyon County homeowners.”
Bridge Maintenance and Agricultural Access
The budget also includes $5 million for bridge maintenance and replacement across rural Canyon County. Several bridges serving agricultural areas south of Caldwell and west of Nampa have been rated as structurally deficient by the Idaho Transportation Department, requiring weight restrictions that force heavy farm equipment to take lengthy detours during planting and harvest seasons.
Canyon County Farm Bureau president David Hendricks praised the bridge funding, noting that restricted bridges cost local farmers significant time and fuel during the busiest periods of the agricultural year. “When a farmer has to drive an extra 10 miles to get a combine across the river because a bridge can’t handle the weight, that’s real money coming out of their operation,” Hendricks said. “This investment pays for itself in agricultural productivity.”
Impact on Canyon County Property Taxes
Commissioner Zach Brooks emphasized that the road budget increase does not require a property tax levy. The funding comes from three non-tax sources: state highway user revenue distributions ($16 million), development impact fees ($8 million), and federal rural road improvement grants ($4 million). Brooks said this approach reflects the commission’s commitment to managing growth without increasing the tax burden on existing Canyon County residents.
Canyon County’s property tax rate remains among the lowest in the Treasure Valley, a point commissioners have highlighted as a competitive advantage in attracting families and businesses to the western side of the metro area. The median home price in Canyon County is approximately $385,000 — roughly $80,000 less than neighboring Ada County.
What Comes Next
Construction on the first phase of road improvements will begin in May 2026, starting with the Nampa-Star corridor and the Middleton Road intersection upgrades. Residents can review the full road improvement schedule on the Canyon County Highway District website. The commissioners will hold quarterly progress reviews at regular Tuesday meetings at the Canyon County Courthouse in Caldwell.
