170th Avenue (Merlo Road and Alexander Street)

170th Avenue will be improved between Alexander Street and Merlo Road. This project is funded for design only.

We are designing improvements for 170th Avenue, including:

  • Replacing the bridge over Beaverton Creek
  • Adding a center turn lane
  • Installing bike lanes
  • Installing sidewalks

We are also considering a traffic signal at Augusta Lane and pedestrian crossing signal at either Vendla Park Lane or Johnson Street.

The project team is working with Tualatin Hills Park & Recreation District to minimize the impacts to the park and improve the entrance on 170th Avenue.
