The city decides to start maintenance after a third chunk falls from the Gardiner

Now that another concrete nugget has dropped from the Gardiner Expressway—the third in the last month—the city has made fixing the old highway an urgent priority. Road crews were supposed to start “controlled chipping” (bashing the concrete to remove loose bits) next week, but will instead start the process today, and may even get help from an outside crew to speed it along. For those curious about what causes the crumbling, the Toronto Star ran a scary graphic showing the anatomy of a fracture (hint: blame salt-laced water). [Toronto Star]
