This is a proposed rendering they have for the replacement school at the Franklin Yard site:
It does not (necessarily) include a connecting road between the existing Centennial Park Roadway and Grand Trunk Street.
Bus access would be directly off Millennium. What they want is a "laneway" extension of the Centennial Park Road along the back of the new school for walking students and for parent drop off. Presumably this would mean paving the Centennial Park Road to allow for all weather two way traffic, but keeping it's current "loop" design beginning and terminating on St. George Blvd. Even though there would be no physical connection between Millennium & St. George, there is no question that traffic on the Centennial Park roadway would increase down by the tennis courts, lawn bowling, playground and Rocky Stone Field. The question therefore is whether or not any increase in traffic through the park is acceptable or not..........
I have drawn in the image below where the two drop off would be.
The rendering also shows new apartment construction on Grand Trunk Street, and a new roundabout at the Millennium/Grand Trunk/Russ Howard intersection. The developer also proposes to buy the existing Bessborough & Hillcrest school sites and redevelop them for higher density residential.
