Airport Station Area
Pedestrian Improvement Project

A main goal of the project is to improve the safety and mobility of all modes of travel, with a focus on people walking and biking. Building on what we heard from the community during Phase 1 of the City Center Plan Update Vision Report, we designed improvements for each of the segments.

While improvements may be constructed on only one side of some streets in this project (as shown in the diagrams below), your input on the proposed road and sidewalk designs will help inform not only current work, but also future projects that may be completed as funding becomes available.

Please review the segment designs and respond to the questions below to share your thoughts.

SeaTac/Airport Station Area

Segment 1: South 176th Street from International Boulevard to 32nd Avenue S
