Video Survey Work along SR 99

Crews working on the SR 99 Tunnel Project will continue to conduct video survey work documenting the existing conditions of underground utilities along the tunnel route. This work is part of a comprehensive program that will help crews minimize ground movement and protect buildings located above and near the route during tunneling.

On Monday, March 11, through Thursday, March 14, crews will intermittently close travel lanes and some street parking within the boundaries of Stewart Street, Seneca Street, Western Avenue and Second Avenue from 7 p.m. to 5 a.m. each night. Please see the attached flier for more information.

To learn more about the monitoring plan, please take a look at the monitoring program folio. If you have questions or concerns, please contact the program hotline at viaduct[at]wsdot.wa.gov or 1-888-AWV-LINE (298-5463).

 Bertha, the world’s largest-diameter tunnel boring machine, is being shipped from Japan to Seattle this spring. Before she arrives, join us for an engaging discussion about how crews will transport her 40-some pieces from a ship at the Port of Seattle to the 80-foot-deep pit to the west of the stadiums where she’ll begin tunneling this summer. You’ll also get a sneak peek at the support facilities we’re building near the launch pit, including a soil-removing conveyor belt that will stretch a whopping two miles by the end of construction.

Archaeology and the Alaskan Way Viaduct Replacement Program

Kevin Bartoy, Cultural Resources Lead for the Washington State Department of Transportation, recently led a discussion at the Museum of History and Industry’s History Café lecture series. Kevin described how state projects must consider cultural resources and some of the mitigation strategies developed as part of the Alaskan Way Viaduct Replacement Program. Kevin went on to discuss the history of Pioneer Square and SODO, focusing on the changing coastline, historical development and the diversity of uses over time.

To dig into the history of the area and discover how Pioneer Square continues to be a hub of transportation and extreme engineering, visit the project information, Milepost 31, at 211 First Ave. S. A video of Kevin’s lecture is also available on the KCTS website.
