Construction on the Waterfront Seattle project has been delayed because of a lack of concrete delivery availability, brought on by the concrete drivers’ strike in King County, according to the Seattle Office of the Waterfront and Civic Projects.

Completion of the project, originally slated for 2024, is now set for 2025. The $756 million project covers twenty acres and includes a new park, a promenade and a pedestrian connection to Pike Place Market.

The strike began Dec. 3. Teamsters Local 174 union said concrete drivers would return to work April 11 while negotiations continue.

“We are now actively working to schedule long-awaited deliveries for items critical to our construction, and are working to assess the overall program delay impacts, as well as potential mitigation strategies,” Waterfront Seattle said on its website.

Most recently, the city has awarded a construction contract for a new Pier 58, according to a news release shared Monday, to begin this fall.

The contract with Pacific Pile & Marine LP is for $34.5 million. In addition to building a new Pier 58, the contract also includes the removal of Pier 63, which has been dilapidated and closed since 2017. Construction is expected to begin in the fall and will take approximately two years, the release said. The former Pier 58 was removed in 2020-21.

“We’re excited to reach this milestone and to be one step closer to having another new pier for the public to enjoy on our waterfront,” said Angela Brady, director of the Waterfront Seattle Program.

Waterfront Seattle said project timelines will be updated and additional information about the park’s progress will be shared as it becomes available.
