## What to know

Navigating to the SeaTac Rental Car Facility requires familiarity with the local highway interchanges. If you are arriving from the east or south via State Route 518, take the exit for 'Airport/Rental Cars.' This route will lead you directly to the access roads of the consolidated facility. Alternatively, if you are traveling on Pacific Highway South (Highway 99), head north and turn right onto the designated entrance for the rental car center complex. The facility is located approximately 2 miles from the main I-5 terminal junction. For returning your vehicle, after checking in, follow the clear overhead signage marked for 'I-5 South/Seattle.' You will need to merge onto I-5 South to continue your journey. Please note that during peak traffic hours, typically between 7:00 AM and 9:00 AM, travel times may increase by 15 to 20 minutes. Ensure you stay in the correct lanes for the merge to maintain a smooth transition during the return process.
