The road from Bare Mountain down to the overpass is mostly already there. Once completed there will be homes built all along the side of skirt mountain with views overlooking Langford lake and the West-Hills project on the other side. On the up side; the Langford trolley will be able to do a loop instead of backtracking.
Indeed, and despite all the smokescreens, it seems that increasing development at Bear Mountain is the real reason for adding this interchange, not safety or congestion relief as the proponents claim.
