Don Valley Parkway
This is a highway that is commonly referred to as the DVP and jokingly referred to as the Don Valley Parking Lot as its often jammed during rush hour.
It's the major north-south expressway on the central / east side of town.
It begins at Lakeshore Boulevard and head north to Highway 401. North of The 401, its no longer in the Don Valley and its name changes to Highway 404, an escape route to cottage country for those who can afford that.
