Status Updates

August 31, 2018

Following Mayor Jenny A. Durkan’s order of an independent review of the Seattle Streetcar, the City of Seattle released an initial summary of findings for full transparency and accountability of anticipated capital costs as well as historical, current and future operating costs. Read the complete press release here.


July 24, 2018

The City provides an update on the progress of the independent review of the Center City Connector. Read the complete press release here.


June 29, 2018

The Mayor wants a thorough and thoughtful analysis that addresses a range of questions related to the costs of this project. KPMG, which was retained to do the independent review of the Center City Connector Streetcar, has not completed the final report but verbally briefed Mayor Durkan on initial findings on June 19. As part of the briefing, the Mayor asked for a further analysis on technical assumptions, ridership projections, operations and capital costs, and funding options, as well as more detailed information regarding additional alternatives for providing transit connections moving forward.

In addition, she asked for a final technical review by City departments including the City Budget Office, SDOT, Seattle Public Utilities, and Seattle City Light to verify updated ridership projections, material costs and labor, utility relocations and project timelines for a series of options to ensure the final report is accurate for taxpayers. With this additional analysis, KPMG will deliver a final report to the Mayor and Council. It is expected that the work can be completed in the coming weeks that will outline operating and capital costs as well as funding risks for both the utility and streetcar work.


March 30, 2018

On March 30, Mayor Jenny A. Durkan directed the City of Seattle to halt the ongoing projects related to the Center City Connector Streetcar, except for work on seismically vulnerable water mains, pending an independent review. Read the complete press release here.


Withdrawal: State Environmental Policy Act (SEPA) comment period

The Seattle Department of Transportation recently issued a SEPA determination of non-significance (DNS) for the South Lake Union Streetcar Operation and Maintenance Facility Expansion. SDOT determined that the project would not have significant adverse impacts on the environment after review of a completed environmental checklist and other information on file with the lead agency. However, following a decision by the City of Seattle to halt project activities, SDOT has decided to withdraw the DNS until further notice. If the project resumes a new notice and comment period will be provided.

Weekend work – storm drain repair at 1st Ave and Cherry St


Crews will be working on Saturday, November 17, to repair an existing storm water pipe in the intersection of 1st Ave and Cherry St. While completing final inspections, crews discovered the collapsed storm drain pipe (which had not been identified for repair prior to the start of construction) and must repair it before the winter rainy season. This unplanned utility repair will start on Friday, November 16, when crews will remove pavement over the damaged pipe. Work on Saturday will include excavation, pipe cutting and fitting, and backfilling. On Monday, November 19, the excavation area will be paved. While crews are working, eastbound Cherry St will be closed at 1st Ave. 1st Ave will be reduced to one lane in each direction from Yesler Way to Columbia St. Sidewalks will remain open.

Please expect noise and vibration, as well as typical construction impacts such as temporary lane and parking closures, increased dust, truck activity, and exhaust.

Night work at 1st Ave and Yesler Way intersection


Crews will be repairing a drainage line at the 1st Ave and Yesler Way intersection from 9 PM Monday, November 19, to 9 AM Tuesday, November 20. The work requires access through the sewer and is scheduled to occur overnight to take advantage of lower sewage flows during that time. While crews are working, the southbound parking lane on 1st Ave, near Yesler Way, will be closed. This work is weather dependent and will require the intermittent use of a compressor, which may create noise during work hours.

Crews will be completing a water service connection on 1st Ave S just north of S Jackson St on Monday, November 19 and Tuesday, November 20, between 7 AM and 5 PM. This work will require crews to remove pavement, connect the pipe, and repave the area. Crews will maintain one lane of traffic in each direction on 1st Ave S between S Jackson St and S Main St. Impacts include noise from jackhammering, as well as increased dust, truck activity, and exhaust.



The week of November 18, crews will work to complete a few remaining items if not completed during the previous week. These work items may include:

  • Repairing an existing drainage line at the 1st Ave and Yesler Way intersection
  • Installing lane striping and roadway markings
  • Landscaping work, such as resetting pavers, and repairing the sidewalk and curb in various locations
  • Consolidating and removing equipment and materials
  • Some of the work is weather dependent. Please expect noise and vibration, as well as typical construction impacts such as temporary lane and parking closures, increased dust, truck activity, and exhaust.

Construction hours

  • Typical construction hours are 7 AM – 5 PM, Monday – Friday. Construction-related noise may be heard as early as 6:30 AM as crews refuel equipment and begin staging for the day.
  • Occasional weekend work

Ongoing traffic lane restrictions, street closures, and other impacts

  • Temporary lane closures on 1st Ave and 1st Ave S between Cherry St and S Jackson St will occur intermittently until construction is complete
  • Intermittent lane closures on S Jackson St and Cherry St for punch list activities
  • Construction staging will remain on the south side of James St, between Yesler Way and 2nd Ave, until construction is complete
  • Expect typical construction impacts such as increased dust, noise, vibration, and truck activity

Construction workers working on utilities

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 2020. 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.

We’re committed to helping people park efficiently. This project includes funding for, a program that makes it easy to find parking availability, rates (some as low as $3/hour), and directions allowing downtown visitors to park in a garage and get to their destination easily on the streetcar.


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.
  • Check out our FAQs and expected water shutdown map for phase 1 (south of Madison St) at this this link
  • Check out our FAQs and expected water shutdown map for phase 2 (north of Madison St) at this this link

signage icon

Street closures and detours

During Pioneer Square utility construction, northbound lanes of 1st Ave between S Jackson and Yesler Way 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

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
