A full summer for Milepost 31 before closing in November
Milepost 31 in Pioneer Square is gearing up for a busy summer of programming. Our information center continues to offer free public viewing platform tours to see the SR 99 tunnel’s south portal construction site. Bike tours have also resumed, which follow Bertha’s tunnel route and provide a unique way of understanding the historical and engineering aspects of this megaproject. You can sign up for tours online or in person at the center.
Our First Thursday speaker series continues on Thursday, June 1. Casey Ralston, the education coordinator at the National Oceanic and Atmospheric Administration (NOAA) Northwest Fisheries Science Center, will provide an overview of NOAA and its work in Seattle and Elliott Bay.
This will be your last summer to visit Milepost 31. After six years and 70,000 visitors, the center will close in late November. The center was created as part of the program’s agreement to help draw visitors to Pioneer Square during SR 99 tunnel construction and educate the public about the neighborhood’s fascinating history and the impressive engineering behind the Alaskan Way Viaduct Replacement Program. With tunneling complete, the program’s commitment has been fulfilled. We appreciate the members of the public and project partners who have helped make Milepost 31 a success and we hope to see you there this summer!
