Exit off of US Highway 60 at Power Road (Exit 188) - DO NOT TAKE THE SOSSAMAN ROAD EXIT OFF US-60. Merge onto and proceed south on Power Road for approximately 4.5 miles to the intersection of Power Road and E Ray Road. Turn left on E Ray Road. Ray Road immediately veers sharply to the right and becomes S Sossaman Road. As you proceed, you will have a reasonable view of the airport across desert terrain on the left and a golf course on the right as you drive towards the main development of the airport on S Sossaman Road. APS's International Headquarters facility (pictured below) is on left side of Sossaman Road. It is the two-story hangar/office complex  (marked 5865) just past the Phoenix-Mesa Gateway Airport Administration building. Our reception office is accessed through the main entrance and then by taking the elevator to the second level. Follow the signs to the flight-line side of the office building. Driving Directions
