We are writing to provide you with the latest information about our hospital addition construction project. 

Activities for the Week of March 3
We have made great progress in completing about two-thirds of the trenching and excavation work along Boren Avenue between Spring and Seneca streets to install an electrical duct bank. We plan to complete work on Spring at Boren early in the week of March 3, and begin refilling and repaving work immediately thereafter.

Most of the work this week will be in the intersection of Boren and Seneca, and it will continue west onto Seneca between Boren and the entrance of the John Winthrop Apartments. Immediately south of the south crosswalk at this intersection, there is a storm drain connection to be made, which will require additional trenching across Boren this week.

Heavy steel street plates will continue to be utilized in covering any opened areas each evening. Extra efforts have been made to ensure the plates are not excessively noisy when crossed by vehicles. 

The first four parking spaces on each side of Seneca, west of Boren, have been closed to facilitate this work and accommodate the routing of traffic onto Boren. Additional parking spaces along the north, westbound lane of Seneca may need to be closed, including a Zone 21 Permit Parking Load/Unload area, to ensure the safety of the public and workers on the site.

This work will take place between 7:30 a.m. and 6 p.m. on weekdays only, with the majority of the work between 9 a.m. and 3 p.m. We plan to complete this work during the month of March. 

Looking Ahead
The trenching taking place this week along the north side of Seneca is in preparation for the installation of an electrical vault, which will affect the street and sidewalk on the north side of Seneca to the east side of the entrance to the John Winthrop Apartments. At this time, we have scheduled this installation for the week of March 24.

This work may require the removal of two trees along the sidewalk just east of the entrance to the apartments, a decision that will be made by the Urban Forestry Department of the Seattle Department of Transportation. If the trees have to be removed, they will be replaced with new trees upon completion of this work. Any questions regarding these trees can be addressed to the Urban Forestry Department, at (206) 684-5693 or at bill.ames@seattle.gov.

When this work is being done, we will ensure an open pathway is maintained at all times to allow residents of the John Winthrop to enter and exit the building to the west. During non-construction hours, we will maintain a pedestrian path around the excavation area. The management of the John Winthrop Apartments has been contacted directly to inform residents of details of this work in advance.

We will continue to build construction offices in the parking area just south of the Baroness Apartments (1005 Spring Street). Construction on a new temporary exit stairway from the hospital's seventh floor roof terrace down to the Emergency Department sidewalk on Spring Street will continue into March.

No work is planned for the weekend of March 8 and 9.

Street Closures for the Week of March 3

  • Spring Street - Spring between Boren and Terry avenues will be closed until the refilling and repaving work is complete, which we anticipate to be the end of the week.

  • Boren Avenue - The outer southbound lane of Boren is closed and will remain closed throughout March. The inner southbound lane may be closed intermittently during weekdays as needed. Whenever both southbound lanes are closed, traffic control will allow one lane of travel in each direction on Boren. Depending on progress at the intersection of Boren and Seneca, there may be a closure of the northbound lanes of Boren. If that is the case, the lanes will be channeled to allow one direction of travel in each direction on the west side.

  • Seneca Street - The first four parking stalls immediately west of Boren on both sides of Seneca will be closed to parking due to trenching work on Boren and Seneca. One lane of traffic may be closed intermittently during this work, but the other will remain open to route bus and car traffic onto Boren.

Once again, we thank you for your patience throughout this period and apologize for any inconvenience these activities may cause. As updated information becomes available, we will be sure to share it with you.
