Denny Way ITS (Intelligent Transportation Systems) Project

October 21, 2020

What's happening now?

The Denny ITS (Intelligent Transportation Systems) Project will be upgrading traffic signals along Denny Way, between Western Ave W and Minor Ave, to enhance multi-modal travel along this corridor that experiences some of the city's heaviest traffic volume.

Project Description

We use a variety of technologies to improve multi-modal travel across the city, including upgrading traffic signals. These technologies are known as Intelligent Transportation Systems, or ITS. ITS plays a key role in a safe, efficient, and innovative transportation system that works for all travelers. Much of what we do is not visible to the traveler.

This project will have minor impacts during construction to the southeast corner of Denny Park located at Denny Way and 9th Ave N, on Seattle Parks and Recreation property:

  • Install new APS (Accessible Pedestrian Signals) push buttons on a 4.5-foot pushbutton post.
  • Replace existing signal cabinet at this location with a new signal cabinet equipped with a new service disconnect cabinet.
  • Replace curb ramps at this corner and restore sidewalk pavement.
  • A traffic control plan and pedestrian detours will be in place during construction. Adjacent trees will be protected during construction and any disturbed vegetation will be restored.
  • Minor changes within Denny Park have been determined to be de minimis under Section 4(f) of the U.S. Department of Transportation (USDOT) Act of 1966. Compliance with Section 4(f) is required for projects receiving federal funding.

This project is funded in part by the 9-year Levy to Move Seattle, approved by voters in 2015, and by funds by the Federal Highway Administration. 


The project is currently near final design and is anticipated to begin construction as soon as summer 2021. More detailed information about the construction work will be posted on this page as they become available. Please stay tuned and sign up to receive construction updates via email.
