So, the McLaughlin/TCH interchange is considered a "long term goal."
This is of course completely dependent upon provincial funding and cooperation.
Of course, provincial priorities can change quickly. The new roundabout at the westbound on/off ramps at Moapleton Road happened very quickly as soon as the province realized how bad the situation was. I imagine the same thing could happen with McLaughlin. This might happen sooner than people expect (especially if there is a lot of bellyaching and complaining).
