Board advances County Road 170 microsurfacing project from 2026 to 2025
Summary
County highway staff proposed and the board approved a budget amendment to accelerate County Road 170 surface treatment to 2025 using microsurfacing as a cost‑effective interim fix coordinated with the city of Baxter.
County Highway staff asked the board to approve a budget amendment to advance County Road 170 surface treatment from 2026 to 2025 and to use a microsurfacing approach. The presenter said microsurfacing is a thin, resilient surface that can fill surface defects and extend pavement life at lower cost than a thicker overlay, enabling the county to complete a shorter‑term fix this year in coordination with Baxter's contract.
Commissioners asked about the technical differences between a seal coat and microsurfacing; staff explained microsurfacing provides both sealing and improved ride quality while remaining more affordable than full reconstruction. The board approved the budget amendment to move the project forward this year.
