Airport Road/Miley Road intersection improvements

The Airport and Miley intersection has long been one of Clackamas County’s more problematic locations – frequent crashes, long queues, and neighborhood cut-through traffic on Prairie View Drive. This project delivers a focused, data-driven safety solution designed to make daily travel safer and more predictable.

This project will convert the intersection to an all-way stop with an overhead flashing beacon, upgrade intersection lighting to meet current safety standards, install a pan-tilt-zoom (PTZ) camera for real-time traffic monitoring, and will upgrade signs and pavement markings.

The county will coordinate with the City of Wilsonville and ODOT.

Why

• Studies show up to 70% crash reduction at intersections converted to all-way stops
• Injury crashes decline even more dramatically
• Every serious injury or fatal crash is one too many. Our goal is zero
• Small time trade-off (15 seconds or less at peak hours) yields major safety benefits

Schedule

• Design: Through June 2026
• Construction: Fall 2026

Traffic impact
