Use WA-518 West, exit SR 99 South to reach the facility, then reconnect to I-5/I-405.

## What to know

To navigate to the SeaTac Rental Car Facility efficiently, follow these precise maneuvers to ensure a smooth transition. If you are arriving from the south or east, take WA-518 heading West. As you approach the airport area, look specifically for the exit marked for SR 99 South (East Way). Taking this exit ramp will lead you directly toward the consolidated rental car center facility. Once you have completed your vehicle drop-off and returned your keys, you will need to rejoin the major highway network. To get to I-5 or I-405, follow the internal signage for I-5 North/South. You will typically merge back onto SR 99 and then use the dedicated ramps to access I-5. Please be aware that during peak rush hours (7:00 AM to 9:00 AM and 3:00 PM to 6:00 PM), travel times can increase significantly. Always ensure you are in the correct lanes early to avoid sudden merges, as this area experiences high-traffic volume given its proximity to Sea-Tac International Airport.
