Kinnaman Road (198th Avenue to 209th Avenue)

We will improve Kinnaman Road with bike lanes and sidewalks between 198th Avenue improvements and 209th Avenue. A Rectangular Rapid Flashing Beacon (RRFB) is planned for the school crossing at 205th Avenue/Stoddard Drive and Kinnaman Road intersection.

Kinnaman Road is adjacent to the South Hillsboro development and is expected to see increased traffic as Hillsboro grows. Kinnaman Road has also been identified as an enhanced major street bikeway in the County's Transportation System Plan.

Design finish (expected): October 2026
Right-of-way start (expected): September 2025
Construction start (expected): January 2027

Questions and answers

Can additional signs or traffic calming be installed as part of the Kinnaman Road Project?

A Rectangular Rapid Flashing Beacon (RRFB) will help slow traffic down and improve pedestrian safety. The speed limit is expected to stay at 25 mph, which is lower than expected for this type of street. Kinnaman Road is a collector, or a street that that collects traffic from local streets with business centers and larger street. View Road Classifications Infographic

Will the existing Kinnaman Road sidewalks be preserved?

We plan to keep some existing sidewalk in place, however if the sidewalk condition worsens, those may be replaced as part of this project.

Can warm-colored LEDs be used in the streetlights instead of blue-white LEDs on Kinnaman Road?

Street lights will be installed according to County standards.

Why does the design seem to shift the alignment of Kinnaman Road at 209th Avenue?

Our Kinnaman Road improvements are designed to tie into the 209th Avenue Project.

Why not include a pedestrian crossing at Kinnaman Road and 202nd Avenue?

We considered this location, however our traffic analysis and coordination with the school found that 205th Avenue and Stoddard Street would be the best place for a crosswalk with a flashing beacon.
