Lower Don River gets as straight edges for Don Valley Parkway, for the Bloor St to Gardiner Expressway

 

 

In this drawing the darker winding line is the natural flow of the Don River, and the the straight line with the angled hatching is the steel pile created path for the River.

 

“160,000 square feet of steel sheet piling was driven along the edge to contain the embankment at a height of eight feet above the normal river level. The portion of the embankment adjacent to the piling has been backfilled with slag, since its lighter weight will reduce the dead load on the piling.”
