There are changes to both the traffic pattern and the addition of bus stops. Details at gov.bc.ca/highway17ravineway
The main change to road traffic is for a one-half block of Ravine Way (by Tim Hortons) to become one way (west), changing the way cars from Carey area can get to the Pat Bay Hwy.(east). Cars coming from Saanich Plaza (at the middle of Ravine Way) will not be able to turn left. The closed section will become a bus-only lane.
