HPGN D 04 FL AA3816
The station can ONLY be accessed from Eastbound I-580; from Westbound I-580, exit on Vasco Rd and drive east on I-580.  There are two ways to access the station. At the end of the offramp, which tees into Southfront Rd, make a sharp U-turn on the I-580 Eastbound onramp and immediately pull onto the narrow shoulder and the mark on the right.  Alternatively, turn left on Southfront Rd and drive to the next intersection (about 0.2 mi), make a U-turn, returning west. Before reaching the on-ramp intersection, jump the curb and park on the side with the mark set in a slight rise on the right.
