This cache location takes you right across the street from this sign. There is a crosswalk you can take from there to GZ, so no need to jaywalk. The closest parking spots are probably the waypoints I've listed below, as the parking lot adjacent to the cache has concrete barriers set up (not sure why - maybe it's just seasonal). GZ is also a great spot to watch planes just after takeoff from the airport.
Since this is obviously a pretty high-muggle area, the hint will tell you right where it is. There's no need to go anywhere near the road, the cache isn't there.
