McKay / Yergen / Ehlen Roads Safety Corridor



The Marion County’s Intersection Enhancements project recently received the prestigious Oregon ITE “2023 Transportation Project of the Year Award” in recognition of its significant improvements at the Ehlen/Butteville and Silverton/Brush Creek intersections. This project, undertaken with the goal of reducing Crashes and enhancing commuter safety, successfully secured ODOT ARTS safety funds for critical upgrades. The implementation contract was awarded to Brown Contracting, and Western Systems proudly served as the supplier of innovative hardware that brought these enhancements to fruition.

As part of the Safety Corridor Pilot Program, Marion County addressed the safety concerns on McKay / Yergen / Ehlen Roads, a critical corridor with high crash rates. The project aimed to reduce fatal and serious injury crashes by implementing low-cost safety enhancements, including signs, pavement markings, rumble strips, and speed feedback signs.

Engineering Solutions that were applied to improve the intersection safety:

  • Lower Speeds:
    • Collaboration with the Marion County Sheriff’s Office to enforce speed limits.
    • Installation of four driver feedback signs to alert motorists of their speeds.
  • Reduce Lane Departures:
    • Implementation of centerline rumble strips, wider edgeline striping, and guardrail reflectors.
  • Increase Visibility at Intersections:
    • Evaluation and upsizing of signage and markings at intersections.
    • Installation of larger, reflective “Stop” signs, wider stop bars, and improved intersection lighting.

Project Scope and Installation Process

The project scope included advanced warning flashers on the main roadway, enhanced stop warnings on the approach roadways, transverse rumble strips on Brush Creek Dr., approach roadway vehicle detection, and intersection lighting. The installation process seamlessly integrated these components to create a comprehensive and effective safety infrastructure.

Project Outcomes & Recommendations

While outcomes are still being evaluated, the efforts have resulted in tangible improvements. However, two fatal crashes in 2022 highlight the ongoing challenges. Marion County is actively seeking additional funds to address fatal crash locations, emphasizing continuous monitoring, and improvements in education and emergency services.
