How do I get to and from the SeaTac Rental Car Facility using the highway?

Detailed answer

To get to the SeaTac Rental Car Facility from the highway, you have multiple route options. If you're coming from the north, take I-5 South and exit onto SR 518 West towards SeaTac. Continue on SR 518 West for approximately 4.5 miles and exit onto S 188th St/International Blvd. Turn left onto S 188th St and then right onto 24th Ave S, which will lead you to S 160th St. Turn left onto S 160th St and follow the signs to the Rental Car Facility. Alternatively, you can take Highway 99 South from the north and exit onto S 160th St directly. The facility is approximately 1.5 miles from the S 160th St exit off Highway 99 South. For returning vehicles, follow the signs to get back onto I-5 North or SR 518 East. The entire trip should take around 20-30 minutes depending on traffic conditions. The facility is open 24/7 and is located at 18200 International Blvd, SeaTac, WA 98188.
