156th St SE Corridor Improvements


The 156th St SE Corridor project aims to improve the roadway and provide continuous pedestrian facilities along 156th St SE from 35th Ave SE to west of Forest View Elementary School and Gateway Middle School.

Some improvements being considered include:

  • Improving vertical curves along the roadway
  • Providing intersection improvements at 156th St SE and Sunset Rd
  • Adding pedestrian facilities connecting already existing sidewalk strips west of Sunset Rd
  • Constructing pedestrian facilities along 156th St SE between Sunset Rd to Forest View Elementary School and Gateway Middle School


This project is on hold.
