Def: crumbling
\ˈkrəm-b(ə-)liŋ\ - The adjective most likely to be used to describe the downtown Toronto section of the Gardiner Expressway. ;-)
Photographed near NW corner of Lakeshore Blvd and York Street. Expressway ramp reflected in Ice Condos tower curtain wall.

"The elevated section built with concrete girders was not built to withstand the use of road salt in the winter. The salt created corrosion of the steel within the concrete bents (vertical columns and horizontal caps), which expanded and weakened the steel, and caused pieces of concrete to fall off. Remedial work had to be applied starting in the 1990s at a cost of $8 million per year. The remedial work included sealing expansion joints to force the salty water into the drains and extensive patching of the concrete columns. Exposed steel was sand-blasted and repainted.
The annual maintenance costs for the Gardiner Expressway were estimated in 2011 at $12 million per year. According to the City of Toronto, the City monitors the pillars on an ongoing basis and "re-coats" the pillars with new coatings of concrete, giving each new pillar an estimated 30 years of extended usage. A 4.5 kg section of concrete fell down onto Lake Shore Boulevard in June 2011. In May 2012, pieces fell from the elevated section near Jarvis, and a piece fell from the overpass over Parkside Drive. In June 2012, concrete fell from the elevated section at Yonge St. and Lake Shore Blvd. which struck a driver's vehicle causing minor damages."
