What are the driving directions to access the I-5 and I-405 freeways when departing the SeaTac Rental Car Facility?

When departing the SeaTac Rental Car Facility, you will exit the parking garage onto S 160th St. To access Interstate 5, turn right onto S 160th St and drive approximately 0. 2 miles to International Blvd (SR 99). Turn right onto International Blvd, and after about 0. 5 miles, you will see the clearly marked on-ramps for I-5 North towards Seattle and I-5 South towards Tacoma. Alternatively, to access Interstate 405, turn left onto S 160th St from the facility and drive about 0. 3 miles to the SR 518 East on-ramp. Take the SR 518 East ramp and merge onto the freeway. Continue on SR 518 East for roughly 1. 5 miles until you reach the interchange for I-405. From there, you can take I-405 North towards Bellevue or I-405 South towards Renton. Following these specific routes ensures you will not get turned around in the busy airport district. Always stay in the rightmost lanes as you approach the freeway entrances to avoid missing the on-ramps, and observe the 25 mph speed limit on S 160th St.
