Contest: Share your viaduct memories to commemorate Milepost 31

Posted on Oct 26 2017 2:44 PM

At the end of November, our Milepost 31 information and tour center in Pioneer Square is closing its doors. We are celebrating the visitor center and the many people who helped make it possible with a final celebration and speaker series on Thursday, Nov. 2.

Crowd gathered on sidewalk outside Milepost 31

To commemorate the center, we’re asking you to share your favorite memory or photo of the Alaskan Way Viaduct. Participants will be entered in a contest that starts today and runs through Friday, Nov. 10. Five participants will be randomly chosen and invited on a special tour that will go into the new SR 99 tunnel.

Here is how you can enter the contest:

  1. Visit Milepost 31 and take our trivia challenge. Submitting your answers will give you one entry into the drawing.
  2. On Twitter, share your favorite viaduct memory or photo. Use the hashtag #Byeaduct and tag us (@BerthaDigsSR99). This will give you one entry into the drawing.
  3. Don’t use Twitter? You can email us your photo or viaduct memory to, with the subject line “Viaduct memory.”

Remember: safety first; do not Tweet us or take a photo while driving!

We will conduct the drawing on Monday, Nov. 13, and notify winners via email or Twitter direct message, with the tour planned in early December. Winners will be able to bring an additional person on the tour (everyone must be 18 years of age or older).

For six years, Milepost 31 has told nearly 80,000 visitors the story of the land that became Pioneer Square and the transformative program that is replacing the Alaskan Way Viaduct. Thank you to the visitors from Seattle and around the world who helped make Milepost 31 possible. We appreciate your support over the past six years.
