Executive Summary The Kittitas County Road Safety Plan 2023 is a continuation of a biennial road safety plan program created to reduce collisions within the County Road network. Following the Washington State Department of Transportation's (WSDOT) Highway Safety Improvement Plan (HSIP) grant application methodology for creating a prioritized road safety plan, crash data analysis in combination with staff identification of certain roadway characteristics throughout the County Road network, a list of prioritized projects implementing various countermeasures was created. These projects were further prioritized with engineering judgement using considerations such as estimated project cost, feasibility, and improvement timing. Total project costs were also determined and accumulated, and if needed, broken down in phases to be completed as funding opportunity allows. • Priority One - Huntzinaer Rd Safety Improvements Phases identified by milepost instead of total score because all phases are priority one. Milepost conscious phases allow the county to continue heading south along the corridor. Phase breakdowns are provided in the project description with further cost estimates per phase. ESTIMATED PROJECT COST. • Phase 1- $1,580,700 • Phase 2 - $1,457,775 • Priority Two — Bridge and Structure Improvement 178 bridges and structures were Identified as in need of improvements in previous safety plans as well as the 2023 safety plan. Due to limited county forces, this project will allow the County to solicit an outside consulting service to evaluate and prioritize a systematic way to address these deficient bridges and structures by creating a crashworthy and cost-effective solution. Although the County has already invested in prioritizing and grouping these structures, additional research, planning, and engineering is required to create feasible projects that meet current standards. The desired outcome of this planning effort would be a systematic process to begin addressing the 178 identified bridges and structures. ESTIMATED PROJECT COST- $150,000 • Priority Three — Denmark Rd Denmark Rd MP 0.5 to MP 4.35 has moved up in scoring prioritization. It was noted in our previous 2017, 2019, and 2021 Road Safety Plans as a safety priority. This roadway has five bridges/structures that have deficient or no bridge rail. The segment scoring 100 has a curve that needs safety improvements and contains accident history. This project would provide safety countermeasures to the entire Denmark Rd corridor. ESTIMATED PROJECT COST- $2,704,488
