City staff held a technical briefing for media on Tuesday, during which staff explained the proposed change in plans, which previously called for work to first begin on the eastern end of the Gardiner.
Despite the change in plans, the city's chief planner, Jennifer Keesmaat, maintains that the expressway is still safe.
"There’s no safety issue. The work that is being undertaken is to ensure that the structure continues to remain safe as the due-diligence analysis is being undertaken," she told CBC News on Tuesday.
Pieces of concrete have fallen off the Gardiner Expressway on at least seven occasions since May of last year, according to a list of known incidents that is posted on the City of Toronto website.
City council still has to make key decisions on the future of the expressway, including on what to do with its eastern end beyond Jarvis Street. But that debate won’t take place until next year.
