Great article from dandyhorse about how the west end is almost totally cut of from the lakefront (and how to change that):
Standing at the foot of Roncesvalles “where King meets Queen”, you can see Lake Ontario only a few meters away. A slight hill creates the illusion that nothing separates you from that enticing blue. It might come as a surprise, but historically this was the case. Parkdale was known as a waterfront neighbourhood and a prime beach destination with Sunnyside Amusement Park.
All of this changed in the 1950s with the demolition of most of the Sunnyside facilities and the construction of the Gardiner Expressway. Today, Parkdale is still adjacent to the waterfront, but six lanes of some of the most congested highway in North America separate the neighbourhood from the water. Accessing the lake and the Martin Goodman Trail has become complicated.
