This project will reconnect the Slabtown neighborhood and NW Portland by extending NW 20th Avenue and NW Thurman Street. This will create a new intersection and a new, more efficient, route for people driving and walking in this growing area.

  • Travelers going between NW 23rd and NW 19th Avenues should plan to travel along NW Wilson St or Thurman and NW Raleigh Streets.
