What are the detailed driving directions to the SeaTac Rental Car Facility from I-5, I-405, and SR 518, and what ongoing construction alerts should I be aware of?

At a glance

From I-5, take exit 152 for SR 518 west, then follow signs to the Rental Car Facility via International Blvd and S 170th St. From I-405, take exit 1 for SR 518 west. Expect delays due to ongoing construction on S 170th St and at the facility entrance; the project runs through December 2025.
