Utility Locating Work Will Pause Until 2018

The holidays are quickly approaching, and crews are working to pack up and clean the work areas this week and next week. Utility locating work will resume after January 1.


Nighttime intersection work on hold until the New Year

We’ve updated our construction schedule and determined that nighttime intersection work will begin in 2018 instead of the week of November 13.

In January, crews plan to work at night to confirm utility locations. We’ll share more details as the work gets closer.



Temporary water main installation to begin

Also in January, crews plan to install the temporary water main along the curb and connect it to buildings on both sides of 1st Ave S between S Jackson St and Yesler Way and on a small section of S Jackson St.

We’ll share more details as the work gets closer, but please expect:

  • Northbound lanes on 1st Ave S between S Jackson St and Yesler Way will be closed for several months. Intersecting streets will remain open
  • The westbound lane on S Jackson St between Occidental Ave S and 1st Ave S will be closed for several months.
  • Parking along 1st Ave S between S Jackson St and Yesler Way will be removed
  • Temporary water shutoffs for some customers*
  • Intersection closures during nights and weekends

*The timing, number, and duration of water shutdowns will vary by location. We’ll continue to share updates on our webpage, and Seattle Public Utilities will contact building managers, businesses, and residential buildings to coordinate timing in advance. Check out our FAQs and expected water shutdown map.



Puget Sound Energy (PSE) and Seattle City Light (SCL) are also conducting work in the area.

Street and Right of Way Improvements:

  • Improved water, sewer, drainage, electrical, and natural gas services.
  • Improvements to all-way scramble intersections at Pike, University, and Cherry streets will designate pedestrian crossings more clearly.
  • Improvements at all intersections and corners will enhance the pedestrian experience and ensure ADA access.
  • The new streetcar will run every 5 minutes at peak times and will connect more people to 1st Ave to live, work, shop, and play.

What to expect during construction

Center City Connector Streetcar construction will be completed in phases between late 2017 and late 2019. We’ll start construction in Pioneer Square, then gradually move north. Here’s what you can expect during the first phase of construction:

parking icon

Parking and load zone changes

The streetcar will have dedicated lanes on 1st Ave so it can run reliably every 5 minutes at peak times. To allow space for the dedicated lanes – while also balancing other modes like walking, biking, deliveries, and through-traffic – most on-street parking along the route will be removed.

  • We’ve been working closely with businesses and residential buildings to replace load zones 1 for 1 within a block of their existing locations. We’ll start adding the new load zones in mid- to late September on side streets off 1st Ave.

Water utilities icon

Planned water shutdowns

Before we can begin the streetcar track work, the existing water main must be relocated and replaced along the route. Water shutdowns will be required as we install temporary and new water mains and connect customers to them. During the first phase of utility construction, planned water shutdowns will affect businesses and residences on 1st Ave and on side streets from about S King St to Madison St.

  • The timing, number, and duration of water shutdowns will vary by location. We’ll continue to share updates on this webpage, and Seattle Public Utilities will contact building managers and businesses to coordinate timing in advance.

Street closures and detours

During Pioneer Square utility construction, northbound lanes of 1st Ave between S Jackson and Cherry streets will be closed to traffic. This is to allow for space to preserve the London Plane trees in the center median. There will be intermittent northbound local access as crews move work zones and complete sections.

  • Any intersection closures will be planned for nights and weekends
  • Sidewalks will remain open during construction except in small sections on a temporary basis

How will businesses be supported during this work?

We’re committed to working closely with impacted businesses and residents during construction:

  • Crews will maintain business access throughout construction
  • Creative signage will help direct customers to businesses
  • The Small Business Development team at the Office of Economic Development has business consulting services available to support small businesses along the route
  • We’ll keep neighbors informed through email updates, flyering, signage, a 24-hour hotline and more
