Denny Way ITS (Intelligent Transportation Systems) Project
December 27, 2023
What's happening now?
We have completed all electrical and concrete work along the Denny Way corridor! Thank you to neighboring residents and businesses for your patience and cooperation as we complete this construction work.
On November 3, 2021, we hosted a construction drop-in session. During the online event, we answered questions about:
- Project improvements
- Construction impacts
- Pedestrian access and crossing times
- Signal timing adjustments
- How to stay informed
You can access the online event summary here, a full recording of the event here, and read a summary of the Q&A session.
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 Accessible Pedestrian Signals (APS) 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.
