Construction forecast at-a-glance
Major construction on 23rd Avenue is now scheduled to begin in mid-May, starting with Work Zone A located between S Jackson and E Cherry streets. However, before the contractor can begin rebuilding the street, Puget Sound Energy and Seattle Public Utilities need to complete some preliminary work.
Puget Sound Energy work through March 31
Crews working for Puget Sound Energy need to determine the exact location of utilities under the street. This is done by "potholing" locations in the street using a truck-mounted machine.
What to expect:
- Short-term, single lane closures in spot locations between S Jackson and E John streets
- Driveway and sidewalk access will be maintained
- Flaggers where needed to direct traffic
- Work hours:
- Weekdays between 9 AM and 3:30 PM
- Short-term daytime work Saturday, March 28 at 23rd Avenue and E Jefferson Street*
- Short-term daytime work Sunday, March 29 at 23rd Avenue and E Union Street*
* A Uniformed Police Officer will be directing traffic at the intersections of 23rd Avenue and E Jefferson Street (Saturday) and E Union Street (Sunday).
Seattle Public Utilities work to start in April
Starting as soon as April 1, Seattle Public Utilities (SPU) crews will begin preliminary work to replace older water service lines before major water main replacement begins in mid-May. See the basics below - we will share more information in the next email update.
What to expect:
- Short-term lane closures (up to one in each direction)
- Driveway and sidewalk access will be maintained
- Flaggers where needed to direct traffic
- Temporary water service interruptions for some customers
- Interruptions are expected to be no longer than two hours
- SPU will notify affected properties prior to this work
- Work hours:
- Weekdays between 9 AM and 3 PM
- Weekends (Saturday and Sunday) between 9 AM and 6 PM
Miss the pre-construction open house? View all the information online
We had a great turnout at our March 5 open house at Garfield High School. We connected with residents, business owners and commuters about what to expect during construction and how 23rd Avenue will operate once the project is complete for people driving, taking transit, biking and walking.
If you didn't make it to the meeting, you can visit our community construction resource site to see the materials we shared. This site has a Google Translate feature to view the information in over 50 languages. Feel free to share the link with your neighbors.

23rd Avenue Corridor Improvements Project
The purpose of the 23rd Avenue Corridor Improvements Project is to improve safety and mobility for people who drive, walk, bike and take transit. Phase 1 of the project includes modifying 23rd Avenue from a four-lane street to a three-lane street. This means one lane in each direction with a center turn lane. This phase of work also includes new pavement, sidewalk improvements, traffic signal improvements, lighting improvements and public art. Click here to view the project fact sheet.
