10 frwy east across the river at Blythe. First exit is Erenburg. Exit and go left over the frwy to the botom of the hill. Right at the stop sign. (Slow through town, 35MPH!) This road runs up through the C.R.I.T. Indian Reservation and will take you right into Parker, AZ.
MUCH SAFER then Desert Center / Rice road. Only 8 miles farther! Worth the extra for a much safer route.
Safe Travels!
