a "greater than six-degree curve" in the highway, necessitating drivers to slow down. Gardiner rescinded his opposition to the change in March 1958 after visiting the site with a delegation from the City and historical societies. In 1959, Fort York was again under threat. A proposal was published to link Highway 400 to the Gardiner to meet in the vicinity of the fort. Gardiner proposed that Metro Toronto and the City share the costs of relocating the fort to the waterfront. In the end, the fort was not moved, the westbound on-ramp from Bathurst Street was cancelled, no interchange was built in the area and the Highway 400 extension was never approved. The Gardiner passes over some of the fort's property, and its width is wider in the area to provide for a possible connection with the 400. The highway is also extra high to allow for possible multiple interchanges. Construction Construction on the expressway began in 1955 with the building of The Queensway and the Keating Avenue (now Lake Shore Boulevard East) extension to the foot of Woodbine Avenue. The Gardiner was built in segments, with the final section being completed in 1966. The cost was approximately $110 million ($ in dollars). Construction of the first part of the actual Expressway started in 1956 with the Humber River bridge, followed by the Humber to Jameson segment. Max Tanenbaum's York Steel supplied the iron girder sections that supported the road deck on the elevated sections. Humber River to Jameson Avenue The route of the Expressway around Humber Bay necessitated the demolition of the Sunnyside Amusement Park on the lake shore, which had existed since 1925. Some amusements were moved to the CNE, others sold off or just destroyed. The carousel was moved to the newly built Disneyland. The Amusement Park lands were subsumed by the Lake Shore Boulevard expansion to six lanes. Only the Palais Royale hall, Sunnyside Bathing Pavilion and Sunnyside Pool were not demolished. A pedestrian bridge crossing was built from the foot of Roncesvalles Avenue to the Palais Royale site. To the east of Sunnyside, the 1800s-era 'South Parkdale' residential neighbourhood at the foot of Jameson Avenue was demolished in 1957. The Expressway, like the railway just to the north, was cut through the area at lake shore level. An interchange was built at Jameson with on and off ramps to Lake Shore Boulevard, and Lake Shore
