 Because of their short lengths, Wayne Gretzky Drive and Groat Road will be the only freeways in Edmonton not to have a highway designation, until the completion of Terwillegar Drive.66 Street and 75 Street functions as the southern extension of Wayne Gretzky Drive.It begins as "66 Street" at 41 Avenue SW and passes north through Mill Woods, passing by Mill Woods Town Centre, Grey Nuns Community Hospital and Mill Woods Golf Course.
