## What to know

Departing the SeaTac Rental Car Facility requires careful navigation to seamlessly merge onto the major regional freeways. After completing your vehicle pickup on the ground level, follow the designated exit lanes which will route you out of the parking garage onto S 160th St. Upon exiting the facility, you will approach a traffic light at the intersection of S 160th St and International Blvd (Highway 99). To access Highway 99 South, turn left at this intersection; the southbound on-ramp is located just 0. 2 miles down the road. For faster interstate access toward I-5 South or I-405 South, turn right onto International Blvd and drive approximately 0. 5 miles north. You will then turn right onto S 150th St, which leads directly into the major freeway interchange. Follow the clearly marked overhead signs directing you to either I-5 South towards Portland or I-405 South towards Bellevue. The drive from the rental facility exit to the I-5 on-ramp typically takes around 4 minutes under normal traffic conditions. Always stay in the rightmost lane when approaching the interchange to ensure a smooth and safe merge onto the interstate highways.
