SR 509, I-5 to 24th Avenue S. – New Expressway Project – Process and Schedule Updates

What’s next?

On December 2 2020, we selected Atkinson Construction as our design-build contractor. Their proposal received the highest score of the three contractors who submitted proposals. They offered the best value, which is a combination of design, plans to minimize impacts, and price.

Throughout 2021, Atkinson will finalize the designs for the SR 509, I-5 to 24th Avenue S. Expressway Project. They will break ground on the project in early 2022. Before they begin construction, we will hold a construction open house to introduce the design-build team to the community and to provide more details about construction and schedule.
