Edmonton
Original plans called for Alberta Highway 2 to continue into Edmonton, akin to the Deerfoot in Calgary, using 91st Street then descending into the Mill Creek Ravine. However residents along Mill Creek as well as many others who did not wish to have portions of the river valley destroyed at the expense of a freeway opposed the plans and as such they were never completed. The only portions to be completed were 91st Street and the James MacDonald Bridge.
