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 significant work happening at the surface above and near the tunnel route.

Seattle Tunnel Partners' tunneling machine repair effort is ongoing
Seattle Tunnel Partners and manufacturer Hitachi Zosen are repairing and enhancing Bertha, the SR 99 tunneling machine. Crews built a 120-foot-deep pit to access the machine. The pit is located between South Jackson and South Main streets, just north of where crews stopped tunnling in December 2013. The machine tunneled into the pit in March 2015. Here's an aerial shot of the pit:
On March 30, 2015, STP safely placed the front end of the SR 99 tunneling machine on the repair platform located just south of the access pit. Below are photos of the front-end lift and the massive piece sitting on a platform, awaiting repairs.
Crews are now making repairs and enhancements. Here's a photo of the machine's new gear ring:
Below are links that illustrate STP's plan to resume tunneling. The contractor's latest schedule is available here.

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.
