Lake Shore Boulevard is ‘released’ to become a Grand Urban Street• Lined with mixed-use buildings on both sides • Bump-up of property values on the south side of Lake Shore by removing the
blighting influence of both the Gardiner and the Railway

rail corridor• The existing Gardiner remains operational during
construction of the replacement deck• Traffic disruption is minimized during construction
