Thomas St: 5th Ave N to Eastlake Ave E

Updated: October 18, 2019

What's Happening Now?

We are working with Washington State Department of Transportation (WSDOT) North Portal project to make changes to the way east-west streets operate as 7th Ave N construction re-connects the street grid. This project will change access to Thomas St at two locations:

1. 5th Ave N - Thomas St will be closed to vehicle traffic east of 5th Ave N to the alley

2. Dexter Ave N - Thomas St will function as a right in - right out street

This is SDOT's Phase 1 of a larger project to enhance the walking and biking connection between South Lake Union and the Seattle Center. Construction of these diverters may begin as early as November 2019. 

What To Expect During Construction?

  • Work in the public right of way near your home or business
  • Typical noise, dust, and activity in the work area during work hours, Monday - Friday, 7 AM - 7 PM
  • Occasional traffic or lane restrictions, including side street closures
  • Temporary on-street parking restrictions with "No Park" signs placed 72 hours in advance
  • Temporary detours for people walking, biking, and driving to get you safely around work zones. Pedestrian access to homes and businesses will be maintained at all times.
  • Construction equipment and stockpiled materials in the work area
  • Work is weather-dependent, and the schedule is subject to change

Project Background

Thomas St is an important east/west green street and public realm connection, linking the Cascade neighborhood through South Lake Union to the Seattle Center. This project is associated with the Thomas Street Redefined Plan and is identified in the Bicycle Master Plan.

Before opening of 7th Ave N and Thomas St signalized intersection to vehicular traffic by Washington State Department of Transportation (WSDOT), this project will construct an interim closure of 5th Ave N and Thomas St and install an interim turn/through restriction at Dexter Ave N and Thomas St. This work is planned to be completed in coordination with WSDOT in 2019.

By opening date of Seattle Center Arena, this project will construct a protected intersection at Thomas St and Dexter Ave N. The protected intersection will include a traffic signal to make it easier for people walking and biking to cross Dexter Ave N. This will provide an important connection in the citywide biking network by linking Thomas St to the popular Dexter Ave N bike lanes. 

Thomas Street Redefined

Thomas Street Redefined is a community-driven, visionary concept plan for a pedestrian and bicyclist-oriented corridor connecting the Waterfront, Uptown, Seattle Center, South Lake Union, and Eastlake neighborhoods. This project will begin implementation of the Thomas Street Redefined vision by establishing the vehicular use of Thomas St as defined by the vision in coordination with the 7th Ave N project. More intermediate and permanent improvements will follow as early as spring 2020.

Thomas Street Redefined consist of two parts: West of Seattle Center (connecting Seattle Center to the Elliott Bay Trail via Thomas St Overpass) and East of Seattle Center (connecting Seattle Center to Eastlake). This project is the first phase of the East of Seattle Center connection.

What's a Neighborhood Greenway?

Neighborhood greenways are safer, calmer neighborhood streets for you, your family, and neighbors. We make people walking and biking the priority. Neighborhood greenways provide connections for people of all ages and abilities to walk and bike between their homes, jobs, and community destinations.

Thomas Street is identified as a neighborhood greenway in the Bicycle Master Plan because it is a non-arterial street that provides an important connection in the citywide bicycle network. The implementation of the Thomas Street neighborhood greenway will be based on the Thomas Street Redefined concept plan.

Schedule
