Countywide curve warning signs

The Federal Highway Administration (FHWA) awarded $177,000 through the Highway Safety Improvement Program (HSIP, CFDA 20.272) to the Washington State Department of Transportation on November 13, 2025, with a completion deadline of December 31, 2029. The award funds a countywide curve safety initiative consisting of data collection and evaluation of curve conditions on the county road system, followed by strategic upgrades and installation of curve warning signs and chevrons. This work aligns with HSIP's core objective of reducing traffic fatalities and serious injuries through data-driven, localized safety improvements on public roads.

The Washington State Department of Transportation passed the funding to the County of Okanogan Department of Public Works as sub-grantee to execute the project work. The sub-awardee will implement the curve warning sign and chevron installations on county roads in rural Okanogan County, Washington, representing a typical rural infrastructure safety enhancement activity within the HSIP portfolio, which has experienced significant acceleration in award volume and geographic distribution over the past 18 months.
