205th Avenue (Baseline Road to Quatama Street)

205th Avenue is narrow between Baseline Road and Quatama Street. A bridge over Beaverton Creek needs to be replaced.

We will design a replacement bridge for 205th Avenue at Beaverton Creek. 

We will begin with a traffic analysis to determine if the road needs to be widened to three lanes (one motor vehicle travel lane in each direction and a center turn lane) or five lanes (two motor vehicle lanes in each direction with a center turn lane). 

Additional improvements include:

  • Bike lanes
  • Sidewalks
  • Retaining walls
  • Guardrails
  • Street lights
  • Improved storm drainage
  • Storm water treatment facilities

Design start: September 2022
Design finish (expected): November 2023
Construction: Pending construction funding
