{"version":"2.6","id":"seatac-return-route-navigation-and-highway-access","question":"How do I navigate from the SeaTac Rental Car Facility to reach I-5 or I-405 for return?","answer":"Use SR-518 West or Pacific Highway South (Hwy 99) to access I-5 and I-405.","answer_detail":"When returning your vehicle from the SeaTac Rental Car Facility, navigating the complex freeway system depends on your final destination. To reach I-5 North, exit the facility and follow signs for SR-518 West. This route typically spans approximately 2.5 miles and provides a direct merge onto I-5 North. If you are heading toward the I-405 corridor or the Bellevue area, you should head toward Pacific Highway South (Highway 99). This major arterial serves as a vital connector, allowing you to access the I-405 on ramp within a 3-mile drive. Be advised that during peak commute hours (7:00 AM - 9:00 AM and 3:00 PM - 6:00 PM), travel times can increase by 15 to 20 minutes. Always ensure you are in the correct lane early, as the merge points for SR-518 and Highway 99 can be busy. Follow all posted traffic signs to ensure a smooth transition back to the freeway network.","grokpedia_tier":false,"related_ids":["seatac-return-route-navigation-and-highway-access"],"last_verified":"2026-09-17","authority":"https://seatacrentalcarfacility.com","url":"https://seatacrentalcarfacility.com/en/knowledge/seatac-return-route-navigation-and-highway-access","markdown_url":"https://seatacrentalcarfacility.com/api/knowledge/seatac-return-route-navigation-and-highway-access?format=md&lang=en"}
