Editing Line 3 Scarborough (section)

===Reuse of infrastructure===
One of the TTC's redevelopment proposals for the Line 3 lands was to convert the corridor, including the elevated section between Midland and McCowan stations, into a [[linear park]]. This proposed park would be similar to the [[High Line]] in the New York City borough of [[Manhattan]].<ref>{{cite news|url=https://torontosun.com/2015/02/20/ttc-looking-at-making-a-park-out-scarborough-rt/wcm/46a315c4-5fcd-4a27-8df5-373d997ff4a2|title=TTC looking at making a park out of Scarborough RT|date=February 21, 2015|newspaper=Toronto Sun|access-date=January 16, 2019|archive-date=January 16, 2019|archive-url=https://web.archive.org/web/20190116100214/https://torontosun.com/2015/02/20/ttc-looking-at-making-a-park-out-scarborough-rt/wcm/46a315c4-5fcd-4a27-8df5-373d997ff4a2|url-status=live}}</ref>
