Heads up, turkey trotters – as Thanksgiving week begins, drivers should expect continued nightly lane closures on I-5 in Kent and Des Moines next week, from Monday, Nov. 24 through Wednesday morning, Nov. 26.
The lane closures on I-5 will allow crews to continue installing noise walls.
This work is part of the SR 509 Completion Project.
