SR 509, I-5 to 24th Avenue South – Expressway Project – What’s next?

What’s next?

This fall, our contractor will begin work on I-5 and on Kent-Des Moines Road, under I-5. Early work includes shifting southbound I-5 lanes towards the median so crews can widen the southbound I-5 bridge over Kent-Des Moines Road. Construction will ramp up in early 2022 as crews begin work on the new South 216th Bridge.
