The Lower Don Trail will be extended via the new LSBE bridge and the Don Roadway extension as part of the new cycling infrastructure in the Port Lands. I highlighted the path in pink on one of Waterfront Toronto's old handouts. There are two bike bridges, marked in orange. They will be built in part using reclaimed girders from the Marine Terminal 35 site.
The Don Roadway will have a bidirectional bike lane on the west side, as evidenced by the design of the intersection at Commissioners St. The path will branch off north of the bridge, so cyclists may choose to ride along the riverbank, underneath the bridge. The path continues through River Valley Park next to the Polson St extension, passing under the South Cherry Street bridge, and looping around to meet up with the existing bike path on Cherry St.
