I wish they would initiate (at the longest) a 10 year plan to make the #17 free flow from the ferry to where it currently ends (no need to extend further south IMO) I think the master plan is for 6 or so new interchanges along the remaining non free flow portions of highway 17 with the removal of all existing at grade intersections. Oh well, at least we got 1 underway....
Here is the current master plan (but no firm timeline given)

The logical next step would be to build the Beacon interchange, allowing the closure of the MacDonald park, Weiler & Amity intersections and making #17 free flow from the ferry to Mount Newton. Then Keep working south until the project is done.
Honestly though, building 6 (now 5 with McTavish U/C) interchanges is not that large of a project given how much is being spent elsewhere in the province.
