The road ends at the ocean.
If you stand near the crashing waves on Playalinda Beach at Canaveral National Seashore and look south, you can see Launch Complex 39. Built for Saturns, for the last 30 years it has been used for Space Shuttles—until last Friday when the last one flew.
Standing on the seashore, you can see Pad 39A, where Atlantis took off. The gantry rises above the dunes, shrouded in blowing sand and ocean mist just beyond the barricades.
This is indeed the end of the road.
