Madison St closed at Boren Ave June 9-11 for paving

Madison St will be closed at Boren Ave the weekend of June 9-11. The closure will start at 7 PM on Friday and end by 6 AM on Monday. Madison St will be closed in both directions at Boren Ave, and Boren Ave will remain open to two-way traffic. Madison St will be local access only between Boren Ave and Terry Ave. Sidewalks will remain open, and buses will be rerouted around the closure. The closure is needed while the contractor finishes paving the west half of intersection.

See map below showing the signed detour route for people driving. Westbound drivers should turn north on Boren Ave, west on Seneca St, and south on 9th Ave to return to Madison St. Eastbound drivers should turn south on 9th Ave, east on James St, and north on Boren Ave to return to Madison St.

Eastbound E Madison St detoured between 12th Ave and 16th Ave; detour to remain through August

Eastbound E Madison St will remain closed between 12th and 16th Aves while we continue to repave the street. Eastbound traffic is detoured to E Union St and 19th Ave. We expect the eastbound closure and detour to remain through August. Madison St is narrower between 14th and 20th Aves, which is why we need to close one direction of traffic as we repave the street. There is a signed detour for people driving and buses are rerouted.  

What to expect: 

  • Eastbound Route 12 buses will be detoured from E Madison St to E Union St to 14th Ave.
  • Route 2 will be detoured from Union St to Pike St between 11th and 14th Avenues in both directions. 
  • Traffic shifts, lane closures, sidewalk and crosswalk closures, and signed detours for people driving, walking, and rolling. 
  • Pedestrian access to businesses and residences will be maintained.

1st Ave closed at Spring St and Madison St closed at 1st Ave June 10-11

1st Ave in downtown will be closed in both directions at Spring St while the contractor installs electrical conduit and repaves the street. Local access on 1st Ave between Spring St and Madison St will be maintained south of the intersection of Spring St. 

Detours for people driving on 1st Ave:

  • Southbound: Turn east on University St to continue south on 2nd Ave. Turn west on Madison St to return to 1st Ave southbound.
  • Northbound: Turn east on Marion St to continue north on 4th Ave. Turn west on Seneca St to return to 1st Ave northbound.

Westbound Madison St will also be closed at 1st Ave. People driving west on Madison St should turn south on 1st Ave, west on Columbia St, and north on Western Ave to return to Madison St.

The closure is expected to start at 6 AM on Saturday, June 10 and end by 6 AM Monday, June 12. Sidewalks will remain open. Crews will be working at night.

Sidewalk and crosswalk closures 

We are working to maintain pedestrian access by installing protected walkways in the street around construction areas. There is not always enough space to install a protected walkway around construction, and sometimes we need to close a crosswalk or sidewalk. The maps below show areas where some sidewalks or crosswalks are closed. Conditions change often, and these maps are current as of May 25. We will update them as conditions change. Click on the links to view the maps. 

  • Downtown (Madison and Spring streets, between 1st and 6th aves)
  • First Hill (includes area between 8th Ave and Boylston)
  • Capital Hill (includes area between Broadway and 14th Ave)
  • Madison Valley (includes area between 19th Ave to E John St)

Scheduled night work

  • June 9-11:
    • Boren Ave and Madison St intersection for road demo and paving
  • June 10-11:
    • 1st Ave at Madison St and Spring St for road paving 
    • Madison St between Minor Ave and Summit Ave for paving at driveways 

10th Ave E stormwater tank and closure 

We're building a new stormwater storage tank under the street on 10th Ave.10th Ave is closed to cars between E Madison St and E Union St. E Seneca St is local access only between Broadway Ct and E Madison St with vehicle access restricted across 10th Ave. Sidewalks are open in addition to pedestrian access to businesses. Once the new stormwater tank is installed, we'll repave the street. We expect to complete this work as soon as the end of June. 

Read our blog for more about the benefits of the new stormwater tank or view this poster. 

The intersection of 10th Ave and E Union St has reopened. It is expected to close again June 20-21 for paving. Vehicles will be detoured to E Pike St, and people biking should use E Pine St to get around the intersection closure. E Union St will be local access only between Broadway and 11th Ave with access restricted across 10th Ave. Sidewalks will remain open with pedestrian crossing detours in place. Buses will be rerouted around the closure.

Construction overview

Construction for the project is currently 50% complete. We're working to make progress on construction as safely and efficiently as possible. Typical work hours are between 7 AM - 5 PM. The contractor has obtained a noise variance to complete construction activities within allowable noise limits for work outside these hours.

  • Downtown: We're completing sidewalk and road construction activities on Madison and Spring streets. Expect lane reductions, sidewalk detours, and traffic control when travelling east/west between 1st and 7th avenues.
  • First Hill: On Madison St, we're completing sidewalk and road construction activities between 7th Ave and Broadway. People driving can now make left turns from Madison St to Broadway, although left turns will be restricted again when we complete street paving between Boylston Ave to Broadway. This work is expected to begin as soon as mid-June. 
  • Capitol Hill: Eastbound traffic on Madison St is detoured at 12th Ave to E Union St and 19th Ave (see detour map above). We're also working on the south side of Madison St between 12th and 14th avenues and completing road and sidewalk work between 20th and 23rd avenues. 
  • Madison Valley: Roadway work is ongoing between 25th Ave and Martin Luther King Jr Blvd, and sidewalk work is taking place from 20th Ave E to Martin Luther King Jr Blvd. We will soon begin roadwork on Martin Luther King Jr Blvd between E Madison St and Harrison St.

    Project Overview

    The Seattle Department of Transportation and King County Metro are partnering together to bring RapidRide to Madison St.

    The Madison St project area is busy, dense, and still growing. Bus rapid transit (BRT) will provide frequent and reliable bus service. The Seattle Department of Transportation (SDOT) will make street improvements to Madison and Spring streets that will allow King County Metro to operate the service as RapidRide G Line from Downtown to Madison Valley.

    Madison BRT - RapidRide G Line planning started in 2012 as part of the Seattle Transit Master Plan. The project went through a rigorous process to develop the design with community input and secure federal funding to cover almost half of the project cost. The project is designed to meet the following goals:

    Reliability

    • Buses will come every 6 minutes during peak times
    • Bus only lanes and bus priority at traffic signals reduce travel time (by 5 minutes from Colman Dock to Madison Valley) and improve reliability
    • All-door boarding and doors on both sides, so people can board efficiently from new center-running stations (between 9th Ave and 13th Ave)
    • ORCA readers at the stations to pay before boarding
    • Real-time bus arrival information at stations

    Accesibility

    • Station platforms level with bus so no stairs to climb
    • New curb bulbs, crosswalks, sidewalks, curb ramps, and bike lanes in sections

    Equity

    • Serves historically underserved neighborhoods with an affordable and reliable transportation option

    Upgrades and vibrancy

    • Updated utilities and street paving
    • New art and landscaping

    Please visit the King County Metro website for more information about RapidRide.

    Check out this video for an overview of the project:

    RapidRide G Line will serve some of Seattle's densest neighborhoods, and it connects to transit across the region (see map).

    Preparing for Construction

    Businesses are open sign showing business names

    What to expect during construction

    We will work with the construction contractor to build the project as efficiently as possible while maintaining access and mobility, but you can expect to experience construction activities throughout the corridor during the duration of work. 

    Generally, we anticipate construction work to be on weekdays between 7 AM and 5 PM, but there will be times crews have to work on weekends and at night. 

    Work zones

    To limit the amount of time that a particular location is distrupted by construction, the construction contractor's major construction activities will be contained within work zones of up to 1,500 feet (about 4-5 blocks) - with at least 1,500 feet between each major work zone. The contractor is permitted to work in up to 4 work zones at a time. We'll monitor that the contractor completes work in one zone and opens it up to traffic before moving on to the next. Minor construction activities that temporarily close a lane for short periods of time will be allowed outside the major work zones and water main work may occur outside the work zones.We will know more about construction hours and timing once the construction contractor develops their schedule. 

    Construction will generally include:

      • Demolition and removals
      • Utility work (including planned water outages)
      • Rebuilding and restriping

    Dates when work is restricted

    • Thanksgiving Day to New Years Day (winter holiday moratorium) - no construction on 1st Ave
    • Pride Fest - no construction between Broadway and 15th Ave
    • Capitol Hill Block Party - no construction between Broadway and 15th Ave
    • Hospital zone - no closures during the first month after construction starts between I-5 and Broadway

    Demolition and removals

    We will be demolishing and removing parts of the existing roadway and sidewalks on Madison and Spring streets to replace with new asphalt or concrete. See design sheets for more locations.

    What to expect:

    • Vibrations nearby as the construction team breaks up the concrete or asphalt
    • Loud noises
    • Truck traffic to help carry out road debris
    • Typical work hours from 7 AM to 5 PM
    • Weekend work as needed
    • Temporary parking restrictions for months at a time (and permanent parking removal)
    • Traffic shifts and detours for people walking, biking, and driving
    • Temporary driveway, street, and lane closures
    • Intersection closures, typically on weekends
    • Flaggers to help direct traffic
    • Temporary bus detours and bus stop relocations

    Utility work

    These include:

    • Water main pipe replacements on Madison between Broadway and Martin Luther King Jr Way
    • Deep sewer main pipe replacement on Madison between 18th and 22nd
    • Storm water detention pipes on 10th between Madison and Pike, on Madison between 12th and 13th, and on Pike between 13th and 14th 

    What to expect:

    • Excavation to remove existing utilities and install new utilities underneath the street
    • Temporary water mains placed along the sidewalk and/or in the street
    • About 4 planned water outages at and near Madison St; neighbors will be notified in advance of planned outages (see our planned water outage FAQ for more info)
    • Loud noise, dust, and vibrations
    • Truck traffic
    • Some nighttime and weekend work to minimize distruption on neighbors; visit our water outage FAQ for more on what to expect 

    Rebuilding and restriping

    We will be demolishing and rebuilding much of the roadway and some sidewalks along the project area. At this time, we will rebuild the road base and then pave over top with asphalt or concrete. In some locations, only the top layer of asphalt will be removed and repaved. A similar type of work is done for rebuilding sidewalks and driveways. After installing the new road, we will return to paint new striping on the road and install protected bike lanes in sections as designed.

    This includes:

    • Street surface, base repair, and subbase as needed
    • Sidewalks, curbs, and curb ramps
    • Painting new markings on the street

    What to expect:

    • Multiple temporary closures of lanes and driveways to demolish, excavate, rebuild, and pave the road
    • Traffic shifts and turn restrictions 
    • Loud noise, dust, and vibrations
    • Truck traffic
    • Steel plates to access driveways where it is safe and feasible
    • Typical work hours from 7 AM to 5 PM
    • Temporary parking restrictions for weeks at a time
    • Some nighttime and weekend work to minimize traffic impacts

    How long will construction last?

    Construction is anticipated to start in fall 2021. We expect construction to take about 2.5 years to complete and the RapidRide G Line to open in 2024. The construction team will complete the work in up to 4 segments at a time.

    Will construction block driveways?

    Yes. Driveway restrictions needed for paving activities are typically short-term. In spring 2021, we met with many property owners and building managers to discuss specifics for each driveway. Feel free to contact us to request a meeting.

    Will there be sidewalk closures?

    Yes. In most cases, a walkway will be maintained on at least one side of the street. We'll work with the contractor to maintain access to businesses and residences.

    How will parking be impacted?

    When the team is working in a particular work zone, parking will be restricted 24/7 for the duration of the work. People will need to park on side streets or off-street parking lots. Parking on much of the corridor will be removed permanently (see this map for parking specifics). Load zones will also be affected, and new load zones will be added on side streets before construction starts. 

    What happens to my bus stop during construction?

    Many bus stops will be temporarily relocated or closed during construction. To stay up to date about current bus stop closures and relocations, please sign up for Metro's Rider Alerts. If a stop is relocated or a bus is detoured, signs will also be posted along the corridor.

    Staging area at E Arthur Pl and Martin Luther King Jr Way E with Still Essential Workers art

    Staging area at E Arthur Pl and Martin Luther King Jr Way E with Still Essential Workers art

    In preparation for construction, the team identified 6 potential locations for the construction contractor to store equipment and materials near the project area called staging areas. These sites were selected to reduce the construction footprint on Madison St and to enable the contractor to build the project more efficiently. All locations are in the City's right-of-way. Changes to local traffic and access will be required with some of the staging areas, and we're workingwith neighbors to make modifications as needed.

    Staging details:

    • Staging sites will be surrounded by a temporary chain-link fence
    • Contractors will not be allowed to park personal vehicles within staging areas
    • Timing will depend on the location but staging could begin as soon as construction starts and may remain for the duration of construction
    • Business and resident access will be maintained
    • The construction contractor may propose different locations that SDOT would need to approve

    Potential locations:

    Support neighbors during construction

    We know construction is difficult on neighbors. Our team is working to coordinate with neighbors, the construction team, and across City departments to lessen the burden of construction as much as possible including: 

    • Relocating load zones before construction starts 
    • Working closely with SDOT's Hub team to coordinate with other public and private construction in the area 
    • Creating signage tailored for the area with wayfinding and construction information 
    • Outreach team: 
      • Serves as liaison between construction team and neighbors 
      • Conducts construction surveys with neighbors to have direct points of contact and learn about needs 
      • Attends construction meetings and coordinates with construction team to accommodate neighbors as much as possible 
      • Communicates with neighbors through mailings, social media, weekly email updates, flyers, door-to-door, virtual meetings, phone calls, and web

    Supporting local businesses

    Businesses will remain open and accessible during our scheduled construction work. Please continue to support local businesses in person or virtually via Central Area Collaborative and Intentionalist. The Central Area Collaborative is partnering with Intentionalist to support Black-owned and small businesses in the Central District neighborhood.
