Priority 2: Corridor Improvements Countywide <br />This project aims to design, develop and implement a system of embedded LED markers, roadway <br />edgeline rumble strips and/or carsonite delineation markers to enhance visibility, safety and reduce run-off <br />the road accidents on the identified corridors. The corridors have been identified through analysis of <br />collision data from 2019-2023. Although the crash data is tied to smaller segments of the identified roads, <br />the County believes applying improvements to the entire corridor is more appropriate than the <br />countermeasure application to short segments. <br />First, the project will investigate existing technologies, best practices and relevant regulations. The County <br />will assess the viability of different marker designs, materials, rumble strip patterns and options. Then the <br />County will analyze the cost -benefit ratio along with practicality of implementation at each identified <br />corridor. <br />Next, a plan will be developed for the deployment of the selected treatments on the identified corridors. <br />This includes site selection, installation procedures and integration with existing infrastructure. Project plans <br />and Specifications will be assembled to advertise for the construction and implementation of the <br />improvements. It is expected that each corridor will have a unique combination of countermeasure <br />improvements. <br />Corridors Identified through the 2025 Safety Plan Include: <br />Road Name <br />Milepost <br />Reference Location <br />1 <br />Look Rd <br />0.00-3.30 <br />Sanders Rd to Alford Rd <br />2 <br />No. 6 Rd <br />0.00-5.10 <br />Vantage Hwy to Thrall Rd <br />3 <br />Bullfrog Rd <br />0.00-2.70 <br />1-90 to SR 903 Roundabout <br />4 <br />Cove Rd <br />1.14-4.14 <br />Robinson Canyon Rd to Manastash Rd <br />5 <br />Thorp Highway South <br />0.00-5.30 <br />1-90 Exit 106 to 1-90 Exit 101 <br />6 <br />Wilson Creek Rd <br />0.00-4.87 <br />Vantage Hwy to Alford Rd <br />7 <br />Hanson Rd <br />0.00-3.08 <br />Thorp Hwy South to Cove Rd <br />8 <br />Westside Rd <br />0.19-4.17 <br />South Cle Elum to Tree Haven Rd <br />15 <br />
