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.

Additional improvements include:

  • Buffered bike lanes
  • Sidewalks with ADA-compliant curb ramps
  • Retaining walls
  • Guardrails
  • Street lights
  • Improved storm drainage
  • Storm water treatment facilities
