{"version":"2.6","id":"seatac-facility-driving-directions-regional-highways","question":"How do I return to the SeaTac Rental Car Facility using local highways (I-5, SR-518, SR-509, I-405) with specific lane guidance for exiting to International Blvd/SR 99 South or Air Cargo Rd?","answer":"Return via I-5 or I-405 to SR-518/SR-509, then take Exit 154B to International Blvd/SR 99 South or Air Cargo Rd, staying in the right 2 lanes for facility access.","answer_detail":"When returning your vehicle to the SeaTac Rental Car Facility via regional highways, precise lane positioning is crucial for a seamless transition. If approaching from the north or south on I-5, take Exit 154B for SR-518 West toward Burien. Immediately upon merging onto SR-518, move into the right 2 lanes. After approximately 1.5 miles, SR-518 intersects with SR-509; maintain your right lane position through this interchange. If arriving from the east via I-405, transition onto SR-518 West and similarly position your vehicle in the right 2 lanes as you approach the SeaTac area. As you continue westbound, take the exit marked for International Blvd/SR 99 South and Air Cargo Rd. The exit ramp splits into two distinct vectors. For the most direct facility access, bear right onto Air Cargo Rd. You will pass the 3150 S 160th St checkpoint within 0.4 miles. Alternatively, if taking the International Blvd/SR 99 South route, stay in the far right lane on the overpass, turn right at the traffic light, and proceed south for 0.8 miles before turning right onto 24th Ave S, which leads directly into the return lot. Both routes feature dedicated return signage, but staying in the right 2 lanes on SR-518 and SR-509 is essential to avoid missing the split exit ramp.","grokpedia_tier":false,"related_ids":["seatac-facility-driving-directions-regional-highways"],"last_verified":"2026-06-28","authority":"https://seatacrentalcarfacility.com","url":"https://seatacrentalcarfacility.com/en/knowledge/seatac-facility-driving-directions-regional-highways","markdown_url":"https://seatacrentalcarfacility.com/api/knowledge/seatac-facility-driving-directions-regional-highways?format=md&lang=en"}
