The City of Toronto has completed the John Street Corridor Improvements Environmental Assessment Study, which resulted in the following Recommended Design:
The narrowing of the road pavement in order to provide significantly wider sidewalks and boulevard areas as follows:
From four to three lanes between Front Street and Wellington Street;
From four to two lanes between Wellington Street and Adelaide Street;
From three lanes to two lanes between Adelaide Street and Queen Street;
Exclusive right turning lanes northbound at Adelaide Street West and at Wellington Street West and a southbound left turn lane at Wellington Street West in order to maintain an adequate level of traffic service;
A continuous "mountable" curb on both sides of the street to enable a seamless transition into a pedestrian-only space for events, for vehicles to mount the flexible boulevard for deliveries or drop-offs, and to accommodate additional vehicular and cycling manoeuvring on either side of the road in emergencies;
The widening of the east side boulevard between Front Street West and Stephanie Street to provide a 2.5 metre wide flexible space (defined by bollards) to accommodate deliveries and, when not used for vehicular loading/unloading, for pedestrians; and
The provision of urban design elements which consist of a double row of trees where feasible, removable bollards, infrastructure to support special events and distinctive paving materials and patterns.
For further details, see the January 25, 2012 staff report, which includes imagery of the recommended design on pages 16 and 17.
