Project Overview

Project Area –35th Avenue SW between SW Roxbury Street and SW Avalon Way
The Seattle Department of Transportation (SDOT) is launching a collaborative process to review roadway conditions along 35th Avenue SW. As safety is our number one priority, we are committed to preventing collisions and improving safety for all users of the transportation system.

Together we will determine the specific nature and design elements of these changes through the process described below. New safety measures to be considered through this project will include: arterial traffic calming, traffic signal modifications, pavement repair, and pedestrian and bicycle safety enhancements. To address behavioral issues like speeding, distraction and impaired driving, we will develop targeted enforcement strategies and area-specific educational outreach.
