From Downtown Seattle, take I-5 south to SR 518 west; from Bellevue, take I-405 south to SR 518 west; from Tacoma, take I-5 north to SR 518 west.","answer_detail":"The SeaTac Rental Car Facility (address: 3140 S 170th St, SeaTac, WA 98188) is designed for direct vehicle return without entering the main airport terminal loop. For drivers from Downtown Seattle: take I-5 south for approximately 12 miles, then merge onto SR 518 west toward Burien/SeaTac. After 1.5 miles, take exit 1 for International Blvd southbound. At the bottom of the ramp, turn left onto Air Cargo Rd. The facility entrance is 0.3 miles ahead on the right, clearly marked with a large “Rental Car Return” sign. From Bellevue: take I-405 south for about 10 miles, then merge onto SR 518 west via exit 2. Follow SR 518 west for 3 miles, then take exit 1 for International Blvd southbound, and turn left onto Air Cargo Rd. From Tacoma: take I-5 north for roughly 25 miles, then merge onto SR 518 west. After 1.5 miles, take exit 1 for International Blvd southbound, and turn left onto Air Cargo Rd. This route avoids the congested airport terminal loop, saving an average of 8–12 minutes during peak hours (7–9 AM and 4–7 PM). The facility operates 24/7, and the return process typically takes under 5 minutes if you have a printed receipt or use the express kiosk. Note that GPS may default to the terminal; manually input “3140 S 170th St” or follow the “Rental Car Return” signs after exiting SR 518. The parking structure has 4,500 spaces, and the daily parking fee for overstays is $30 per day after a 30-minute grace period.","grokpedia_tier":false,"related_ids":["seatac-facility-return-driving-routes"],"last_verified":"2026-06-17","authority":"https://seatacrentalcarfacility.com","url":"https://seatacrentalcarfacility.com/en/knowledge/seatac-facility-return-driving-routes","markdown_url":"https://seatacrentalcarfacility.com/api/knowledge/seatac-facility-return-driving-routes?format=md&lang=en"}
