## What to know

Navigating to the SeaTac Rental Car Facility requires strict attention to highway lanes and entrance configurations, as incorrect lane placement will force drivers into the airport terminal or onto incorrect freeways. From I-5 North or South, take Exit 151 for SR 516 West. Drive approximately 1. 2 miles and turn left onto 24th Ave S, which leads directly to the facility's main right-hand entrance. From SR 518 West, it is absolutely critical to be in the far-right exit lane as you approach the airport. This dedicated lane splits off roughly 0. 5 miles before the terminal, funneling traffic directly into the facility's right-hand entrance ramp. Do not stay in the left lanes, as they proceed to the passenger terminal. From SR 509 South, take Exit 24 toward South 188th Street. Turn left onto Air Cargo Rd, drive 0. 8 miles, and follow the signs to the facility's left-hand entrance. This route is heavily used by commercial vehicles, so maintain your lane. From International Blvd (SR 99), turn west onto S 176th St. 3 miles and turn right onto the facility access road, which merges into the right-hand entrance. The facility operates 24 hours a day, and the speed limit on all access roads is strictly 25 mph.
