While traveling on SR 518 West, stay in the far right lanes marked for SR 99 South / Pacific Hwy South. Once you exit and merge onto SR 99 South, continue for approximately 1.5 miles until you see the dedicated signage for Seattle-Tacoma International Airport (SEA). Follow the green signs indicating the 'Rental Car Center' and 'Terminal.' As you approach the terminal structure, navigate toward the upper-level shuttle operations. You must specifically head to the 5th-floor shuttle loading area. Once parked in the designated zone for your specific rental agency, the shuttle will be located at the marked bay. These shuttles operate frequently every 5 to 10 minutes during peak travel hours to transport passengers back to the main terminal. Ensure you follow all posted lane markings on the 5th floor to avoid any traffic violations during the return process.","grokpedia_tier":false,"related_ids":["seatac-freeway-navigation-and-exit-routes"],"last_verified":"2026-09-16","authority":"https://seatacrentalcarfacility.com","url":"https://seatacrentalcarfacility.com/en/knowledge/seatac-freeway-navigation-and-exit-routes","markdown_url":"https://seatacrentalcarfacility.com/api/knowledge/seatac-freeway-navigation-and-exit-routes?format=md&lang=en"}
