Nature Beneath the Leaside Bridge: June 2021

Construction of the Leaside Bridge to connect Leaside and East York was begun in January 1927 and inaugurated on October 29 as the Confederation Bridge, in honour of the sixtieth anniversary of that event.


In the late 1960’s the bridge was widened to support 6 lanes of traffic.


Here is how it looked on a very humid early summer day.


I will identify it at the end of the post.

There are many Yellow Warblers in the Don Valley now and a few of this species: the American Redstart.

Sing a song of seasons,
Something bright in all,
Flowers in the summer,
Fires in the fall.                                       – Robert Louis Stevenson (1850–94)

    Such beautiful botany (and Redstart!) Thanks for the wonderful pictures, Miles. As soon as my second vaccine takes full effect (very soon!) I plan to visit this much beloved Valley again (weather and less crowded subway times permitting). I can hardly wait–I’ve missed all this so much! Thank you for enabling me to keep up with it by sharing your wonderful pictures with us!
