  • Limited construction resuming on Seventh Avenue North and in Battery Street Tunnel

    Last week crews working for Kiewit Infrastructure West Co. resumed limited work on the North Surface Streets and Battery Street Tunnel projects. Work in these two areas had been suspended since March due to the COVID-19 pandemic. This low-risk work is occurring in accordance with guidance from Governor Inslee and adhering to the state’s required safety plans required of all contractors.


    Work on Seventh Avenue North

    Before work was suspended, crews had begun building the permanent center medians on Seventh Avenue North. Crews will soon begin breaking out asphalt in the middle of the street where the permanent, planted medians will be built. Forming the concrete curbs and landscaping will come later, when additional types of work are approved. Some turn restrictions remain in place between Denny Way and Harrison Street.


    Work on Battery Street

    There is a substantial amount of work remaining to decommission and fill the Battery Street Tunnel, with construction scheduled to extend into 2021. This includes utility work as well as filling the final (top) seven feet with a low-density concrete. Above ground, on Battery Street, crews still have street restoration activities to complete, such as building ADA-compliant curb ramps and removing and patching over the tunnel’s ventilation grates.

    This month crews are beginning limited work inside the tunnel, preparing for the time when tunnel filling can safely resume. When additional construction activities are cleared to resume, crews will begin pouring and forming ADA-compliant ramps along Battery Street at its intersection with First, Second, and Fourth avenues.

     

    Looking ahead

    “Phase Two” of Governor Inslee’s restart plan will allow a wider range of construction activities. On our project, that will include much of the construction that remains. In addition to the work activities noted above, work will resume at the intersection of Seneca Street and First Avenue. There, crews will rebuild the sidewalk on the west side of First Avenue and do other restoration activities associated with the viaduct off-ramp that used to terminate at the intersection. We encourage our neighbors to subscribe to our construction emails for updates on when that work will resume.

  • Status of project construction work

    In March, the Washington State Department of Transportation suspended work on nearly all of its construction projects statewide. This included most Alaskan Way Viaduct Replacement Program construction on the Battery Street Tunnel and the North Surface Streets projects.
     
    Last Friday, Governor Inslee issued new guidance on the conditions under which low-risk construction may resume. WSDOT is requiring all contractors to develop plans that adhere to the safety protocols outlined in the Governor’s direction. WSDOT and our contractor Kiewit will work closely to identify which project elements may be resumed, and the safety plans and protocols that must first be in place to protect the safety of crews and the public at large.
     
    Certain types of work deemed critical were exempted from the March work-suspension order. On this project, that work entails:
    • Installing a water line at South King Street. That work began in early April and continues, with crews working daytime hours and completing work in accordance with CDC guidelines to ensure the safety of crews and the public.
    • Upcoming weekend work at First Avenue and Seneca Street. This work, at the abutment of the old viaduct off-ramp, requires deactivating the overhead bus trolley wires. This weather-dependent work is planned for May 9-10. Crews plan to work extended daytime weekend hours (6 a.m. - 8 p.m.), and the work will reduce First Avenue to one lane in each direction from 6 a.m. Saturday, May 9 to 6 a.m. Monday, May 11. 

    Work on the Battery Street Tunnel and Seventh Avenue North remains temporarily suspended. Once plans are in place to address safety protocols, crews will begin working on both projects.

  • Battery Street and North Surface Street construction suspended

    In response to Gov. Inslee’s “stay home, stay healthy” order, the Washington State Department of Transportation has suspended work on nearly all of its construction projects statewide. This includes the Alaskan Way Viaduct Replacement Program construction on the Battery Street Tunnel and the North Surface Streets Project. The suspension will last for at least two weeks.

    This temporary halt in construction is needed to help slow the spread of the COVID-19 pandemic and protect the health and safety of our employees, contractor crews and the public at large. We will look to restart our projects when the Governor’s Office and health officials determine it is safe to do so.

    Crews are still planning to complete critical work on a water line at South King Street. This work is exempted from the halt in construction and is scheduled to begin as soon as April 6. That work will be completed in accordance with CDC guidelines to ensure the safety of crews and the public.

    Our contractor Kiewit has closed their jobsite so the site does not pose hazards to the public while construction is halted. We will post updates to our program website and via our construction email list when we have new information to share. If you have any questions about our work, please email us at viaduct@wsdot.wa.gov or reach out via Twitter @BerthaDigsSR99. In the meantime, we wish good health to you, your families and friends. Stay safe!

  • New intersections open on Seventh Avenue North

    People traveling by any mode between South Lake Union, Seattle Center and Uptown now have new options for crossing Seventh Avenue North. Over the past month, crews activated new traffic signals at Thomas and John streets. The Thomas Street intersection is crossable by pedestrians and bicyclists, and the John Street intersection is open to vehicles as well.

    Above: John Street is now open east-west across Seventh Avenue North, but left turns remain prohibited.

    Contractor crews have been working on our North Surface Streets Project for more than a year where Aurora Avenue North once descended into a trench approaching the Battery Street Tunnel. During this work, Seventh Avenue North has been open north-south between Denny Way and Harrison Street, but east-west crossings at John and Thomas streets remained closed.

    This winter crews installed poles and traffic lights at these intersections. The Thomas Street signals were turned on in late February, and the John Street intersection opened Saturday, March 14. Not all vehicular movements are allowed with these activations, however. Left turns remain restricted; see the map below (click to enlarge):

    Above: Left turns onto Thomas and John streets will remain prohibited in this phase due to median construction work (click the map to enlarge).

     

    This phased construction approach on Seventh Avenue North has helped keep vehicles and buses moving during construction. Earlier this month crews began the final phase of roadwork, shifting the work zone to the center of Seventh Avenue North in order to build its center, planted medians. The curb lane remains a bus-only lane (right turns are permitted) while the inner lane is for general purpose traffic. This final phase of work is scheduled to conclude by this summer.

    On March 21, King County Metro plans to open a northbound bus stop and southbound bus stop on Seventh Avenue North (see map above). The stops will be between Thomas and Harrison streets. Routes that take SR 99 / Aurora will uses the stops, providing a shorter walk than today for many people working in the area. Visit King County Metro’s website for updates, including possible service changes due to COVID-19.

  • Happy birthday, SR 99 tunnel

    One year ago today, WSDOT opened the State Route 99 tunnel and watched it quickly become a fast, easy way to bypass downtown Seattle traffic. Traveling SR 99 through Seattle is much safer than it was pre-tunnel, when the Alaskan Way Viaduct carried SR 99 through the city. Drivers now travel underneath Seattle inside a tunnel designed to survive strong earthquakes, with state-of-the-art ventilation, fire suppression and intelligent traffic systems.

    The Alaskan Way Viaduct has been demolished in the year since the tunnel opened. Seattle’s central waterfront has transformed, both visually and audibly - it’s hard to describe how much quieter it is to walk along the water today without two decks of highway traffic roaring overhead.

    With the viaduct out of the way, the City of Seattle is building its waterfront of the future. One of the first elements of that project will open later this winter: a new, two-way bus route on Columbia Street to connect thousands of bus commuters between Third Avenue and points south and west of downtown.

    Tunnel usage

    The SR 99 tunnel now averages more than a million trips each month. To no one’s surprise, the busiest travel times are the peak hours – weekday mornings between 6–9 a.m. and weekday afternoon/evenings between 4–7 p.m. Tolling started in November 2019, and 83% of drivers using the tunnel today have a Good To Go! account, which means they pay the lowest toll possible ($2 less than having no pass or account). The tolls help pay back construction bonds and pay to keep the two-mile-long tunnel running safely and smoothly.

  • Looking back on a year that transformed Seattle forever

    It’s hard to believe that a year ago today, people were driving on the Alaskan Way Viaduct. 
     
    This year we reached the culmination of two transformative projects: we opened the SR 99 tunnel, and demolished the Alaskan Way Viaduct. Both efforts were years in the dreaming, planning and making, and they have forever altered Seattle’s waterfront and how people travel through downtown Seattle.
     

    Here are notable milestones from this year of dramatic progress:

    • Jan. 11: We closed SR 99 for three weeks to #realign99 into the new tunnel. Thousands of people changed their commutes and we all worked together to keep people moving through Seattle.
    • Feb. 2-3: More than 110,000 people showed up for one last walk along the viaduct and a trip through the new tunnel. The public festival included Seattle’s largest-ever fun run and the biggest bike ride in Washington.
    • Feb. 4: Seattle’s new SR 99 tunnel opened to traffic on a snowy Monday morning.
    • Feb. 15: The first chunks of viaduct came out along the old Columbia Street on-ramp as demolition began.
    • May: Crews started recycling crushed viaduct concrete to fill the  the old Battery Street Tunnel.
    • September 21: The last piece of double-deck roadway along Seattle’s waterfront came down.
    • Nov. 21: Demolition done! The final piece of viaduct on the steep hill north of Pike Place Market was cut from its foundation and laid to rest.
     
    We made a video looking back on this remarkable year in Seattle’s history:
     
    Thank you to everyone who tuned in to our live construction cameras, followed us on Twitter, watched our YouTube videos, or simply paused on the sidewalk as giant machines demolished an iconic Seattle highway. However you engaged with our project this year, from WSDOT and our contractors to you, here’s to an unforgettable 2019.
