A public meeting tonight at St. Lawrence Hall on the future of the Gardiner Expressway has heard considerable opinion that the expressway should be saved, but that the portion east of the Don Valley should be torn down. There is nothing definitive to be decided tonight. The expensive task of fixing the Gardiner would be lessened by removing the eastern part. It would apparently permit desirable development. This option would also maintain the rather busy link not just from downtown but distant points to the west with South Bayview and other parts of the City.
