Here are notable milestones from this year of dramatic progress:
- Jan. 11: We closed SR 99 for three weeks to #realign99 into the new tunnel. Thousands of people changed their commutes and we all worked together to keep people moving through Seattle.
- Feb. 2-3: More than 110,000 people showed up for one last walk along the viaduct and a trip through the new tunnel. The public festival included Seattle’s largest-ever fun run and the biggest bike ride in Washington.
- Feb. 4: Seattle’s new SR 99 tunnel opened to traffic on a snowy Monday morning.
- Feb. 15: The first chunks of viaduct came out along the old Columbia Street on-ramp as demolition began.
- May: Crews started recycling crushed viaduct concrete to fill the the old Battery Street Tunnel.
- September 21: The last piece of double-deck roadway along Seattle’s waterfront came down.
- Nov. 21: Demolition done! The final piece of viaduct on the steep hill north of Pike Place Market was cut from its foundation and laid to rest.
