Much of our construction is focused at either end of downtown, near what will become the tunnel's north and south portals. Still, there is plenty of work happening at the surface above and near the tunnel route.

Access pit construction is ongoing

Seattle Tunnel Partners is building a 120-foot-deep pit that will allow crews to access and repair the SR 99 tunneling machine, which is stopped about 60 feet underground between South Jackson and South Main streets. When the pit is complete, the machine will tunnel forward into it. Crews will then partially disassemble the machine, and make repairs and enhancements. Below are links that illustrate STP's plan to resume tunneling by the end of March 2015.

 

Monitor installation complete

More than 700 underground monitors have been installed in the streets and sidewalks along the tunnel route. These instruments are used to track any movement below the surface during tunneling. Learn more about our monitoring program here.

Elliott Bay Seawall work underway

The City of Seattle is replacing the Elliott Bay Seawall — from South Washington Street to Broad Street — with a structure that meets current safety and design standards. Visit the project’s website for the latest news about seawall-related construction.

 

Visiting Pioneer Square or the waterfront? We'll help you find parking

There are a lot of great things to do in the Pioneer Square and waterfront neighborhoods. Since circling the block to find parking isn’t one of them, we launched a parking website to help visitors track down one of thousands of parking spaces within walking distance of shopping, restaurants, attractions and more. The site includes rates, hours and directions to specific lots or garages.
