Living in Cave Creek and working Downtown Phoenix I've had to drive back and forth this freeway for a long number of years. I remember when it ended at Bell Rd. Great memories.
I remember when I moved to Phoenix in 1985, SR51 didn't exist I saw the houses being bulldozed on Missouri Ave near 24th St. In 1989 I took my first trip on SR51, I got on at McDowell and exited on Highland St. That's as far as it went back then.
