pillars, which were resting on soil, not on bedrock, had sunk by a metre, giving the eastbound Gardiner a roller-coaster ride or "Humber hump". The bridges and connecting roadways were replaced at a cost of $100 million. Fatal collisions had occurred at the location, including an August 13, 1995 incident where a speeding eastbound Corvette became airborne and collided with a vehicle in the westbound lanes, killing three people. In the 1990s, after 30 years of usage, the City found that the central elevated section needed extensive repairs, and the ongoing maintenance was expensive. Proposals started to be floated for the demolition of the Expressway. In the end, city council voted to have the elevated section extensively rehabilitated and the elevated section in downtown Toronto was closed down for extensive repairs. On April 1, 1997 the stretch of the Queen Elizabeth Way between Highway 427 and the Humber River was downloaded from the Ministry of Transportation of Ontario to Metropolitan Toronto and was redesignated as part of the Gardiner. Portions of the former QEW had parallel service roads along the roadway: Oxford Street – south side from east of Horner Avenue to Grand Avenue (broken sections) Mendota Road – north side from east of Royal York Road to Grand Avenue Queen Elizabeth Boulevard – north side from east of Islington Avenue to west of Royal York Road Fordhouse Boulevard – north side from east of The East Mall to Wickman Road Brockhouse Road – south side from east of The East Mall The former QEW segment was not upgraded to contemporary standards when it was downloaded to the city, with particular concern over the old steel guard rail median barrier separating eastbound and westbound traffic. The steel guard rail dividing opposing traffic from The East Mall underpass and the Grand Avenue overpass was replaced by an Ontario "tall-wall" concrete barrier in early 2007, although steel guard rail still remains between the collector and express lanes. The city also replaced the province's late 1960s-era truss light poles with shaded high mast lighting (similar to the lighting on the Don Valley Parkway) west of Kipling Avenue and east of Royal York Road, while a rehabilitation project for the railway underpass east of Park Lawn Avenue took place from 2014-15. The elevated section between the Don River and Leslie Street known as "Gardiner East", intended for connection to the cancelled Scarborough Expressway, was
