  • 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.
