SW 209th Avenue is located east of the city of Hillsboro's new South Hillsboro development. Between Alexander Street and Kinnaman Road, 209th Avenue is a two-lane road with dedicated left-turn lanes on both the north and south sides, but no bike lanes. 

Traffic is expected to increase as South Hillsboro continues to develop. We will be:

  • Widening 209th Avenue to five lanes, two travel lanes in each direction and a protected center-turn lane.
  • Improving the grade of the railroad crossing on 209th Avenue, south of Tualatin Valley Highway.
  • Adding bike lanes
  • Improving street lighting,
  • Adding landscaping, sidewalks, signal and bus stop upgrades and drainage.

The work will be done in coordination Cornelius Pass Road, 234th Avenue and 198th Avenue improvements.

Construction start (expected): November 2021
Construction finish (expected): Fall 2023

Update 7/15/2021: We plan to host a construction kickoff before work begins in the fall.
