The new expressway will be built in stages. The first stage of work completed the new Wapato Way East bridge and State Route 99 (SR 99) roundabout in Fife. The second stage builds the expressway between I-5 and the Port of Tacoma. It’s scheduled to open in 2026.

Work on the third stage between SR 161/North Meridian Avenue and SR 410 began in 2025. Construction of the last stage between North Meridian Avenue and I-5 will begin in 2026.

The entire project is planned for completion by 2030.
