The City of Toronto will continue to accelerate construction projects and co-ordinate road closures as it performs significant construction work on the City's roads, sewers and watermains to improve Toronto's aging infrastructure.The City is taking action to minimize traffic congestion during the construction season by extending hours for key projects, bundling projects, implementing signal-timing changes on parallel routes and enhancing signage at work locations. Work hours will be extended for 32 construction projects, including overnight work at nine locations and 24/7 work at another seven locations.The City will invest almost $700 million to maintain and upgrade its infrastructure, including an estimated $310 million for roads, expressways and bridges, $310 million for sewers and watermains, and $70 million for basement flooding protection in 2017.Major projects planned for this year include:• demolition of the eastbound ramp from the Gardiner Expressway to York/Bay/Yonge Streets and building a new ramp at Lower Simcoe Street• watermain work, TTC streetcar track replacement and road resurfacing on Wellington Street from Church Street to York Street• TTC track replacement, watermain work and road resurfacing on Dundas Street from Yonge Street to Church Street• road resurfacing on Birchmount Road from McNicoll Avenue to Steeles Avenue East• road resurfacing and watermain work on Don Mills Road from north of Lawrence Avenue to Wynford Drive• road resurfacing on Burnhamthorpe Road from Dundas Street West to Martin Grove Road• road resurfacing on Lake Shore Boulevard from Leslie Street to Woodbine Avenue• bridge rehabilitation work for Queensway Bridge over the Humber River, and• TTC track work at the intersection of Queen Street and McCaul Street.As a result of the construction, it is expected that the City will complete about 130 kilometres of road resurfacing work and 310 kilometres of sewer and watermain work in 2017.This work is part of the City's comprehensive, co-ordinated strategy to rehabilitate and upgrade Toronto's roads, transit and underground infrastructure for current and future needs.The City continues its efforts to fill potholes.
