Weekend Work

  • No Virginia Mason construction work is planned for Saturday, Aug. 8, or Sunday, Aug. 9. However, please note that Seattle City Light crews will be working in the electrical vaults on Spring and Seneca streets over the weekend.

Construction Continues on Connection from Main Hospital to Addition

  • As communicated in our Aug. 4 special edition bulletin, construction on the connection from the main hospital to the new hospital building began Wednesday, Aug. 5.
  • This construction work will impact traffic at the Seneca drop-off zone, but vehicle access will be maintained. Revisions have been made and appropriate signage installed to the entrance and exit points from Seneca. Pedestrian traffic from Lindeman Pavilion to the hospital is being re-routed to the east side of Terry Avenue, and pedestrians need to use the east crosswalk across Seneca.
  • Initial work involves landscape removal from the island area of the drive-through, temporary removal of the pylon sign, and removal of a tree that is against the main wing wall. Preparations will be made in the island area for construction of a temporary fuel tank enclosure, which will remain until the hospital addition is completed. At that time, the fuel tank enclosure will be removed and the area restored to its pre-construction condition. Existing signage from the pylon will be installed on the new enclosure structure to be built.

Monday through Friday

  • Over the coming weeks, we will continue to dismantle the wall forms used to pour concrete for the elevator cores and remove them from the site.
  • It is important to note the concrete walls you see are not the final exterior walls.
  • Intermittent concrete pours will continue on Seneca and Boren Avenue throughout the week. Concrete trucks will begin pouring at 8 a.m. on Seneca and 9 a.m. on Boren. Seneca and Boren will be limited to one lane in each direction during these intermittent pours. Parking on the south side of Seneca also will be unavailable temporarily.
  • Steel deliveries for the main concrete structure continue this week on Seneca and Spring streets. This work requires temporary parking restrictions on the north and south sides of Seneca (6 a.m. to 6 p.m. weekdays, north side; 24 hours/seven days a week, south side).
  • Activities over the next few weeks will continue to focus on pouring floors, columns, walls, laying rebar, and installing piping and conduits.
  • Residents may hear an air horn on occasion. This is a safety alert to inform workers that a heavy load is about to be lifted across the construction site.
  • View our webcam at We have adjusted the angle of the camera upward, so it shows more of the ongoing work being done at the site.

Sidewalk and Street Closures

  • Spring Street - Spring and its north sidewalk between Boren and Terry avenues will be closed 24 hours a day. The south sidewalk will be open to pedestrians throughout the week.
  • Boren Avenue - The westward southbound lane on Boren between Seneca and Spring will be closed during normal construction hours and open after construction hours. The sidewalk will be closed 24 hours a day.
  • Seneca Street - For the time being, the south sidewalk on Seneca between Boren and Terry will be closed. The north sidewalk will be open.
  • Parking Spaces - The four parking stalls west of Boren on only the south side of Seneca will continue to be closed to parking.
