Clear Roads has published its sixth Annual Survey of State Winter Maintenance Data, which compiles data on winter resources, materials and costs from 36 states for the 2019-2020 winter season. The interactive spreadsheet-based tool includes a United States map that displays many of these metrics. The tool includes six years of data, and displays averages and changes across winter seasons.
