corporations of Toronto. In 2005, a proposal named the "Toronto Waterfront Viaduct" was presented by a group of Toronto citizens, calling for the replacement of the existing elevated expressway with an 8 to 10-lane cable-stayed viaduct over the Lakeshore rail corridor. This proposal combined the freeway with a new Lakeshore light rail transit system, and lanes for bicycle and pedestrian traffic. The proposed design used cantilever bridge structure to minimize disruption of the railroad. By building the replacement route on a parallel corridor, current traffic would not be disrupted. Two proposals were made public in June 2009, when the City of Toronto Council was considering the proposal to tear down the eastern section. Mark Fraser, a Toronto CAD technician, and local resident opposed to the removal of the Gardiner, put forth a proposed design for a complete overhaul of the Gardiner he called the "Green Expressway". The design would consist of either a channel or tunnel built under the Gardiner with two levels of traffic (one for local highway traffic, and one for express traffic through the city), a ground-level local street, and a linear park and retail concourse built above the street. Later in June 2009, Les Klein, a Toronto architect also opposed to the removal of the Gardiner, proposed adding an upper level deck covered with plants, bike lanes, walking paths and solar panels (for expressway lighting) on a stretch of the expressway, entitled the 'Green Ribbon'. The estimated cost was between $500 million to $800 million. Western Waterfront plan The Western Waterfront Master Plan calls for reconstruction of the Jameson/Dunn interchange to place the eastbound lanes of Lake Shore Boulevard onto the north side of the Gardiner, moving the Jameson westbound exit east to British Columbia Drive, converting the Jameson Street bridge into a pedestrian overpass to reclaim approximately of parkland. The Master Plan passed a Class environmental assessment in 2009. The City started to replace several deteriorating structures in May 2010, to prepare the structures for the new roadway alignment. The construction of the realigned Lake Shore Boulevard and the related Gardiner ramp changes is slated for after 2014, after completion of a detailed environmental assessment for the parkland and roadway project. East of Jarvis review In May 2008, Waterfront Toronto (the former TWRC) proposed the demolition of the segment from Jarvis Street to the Don River and construction of a widened Lake Shore Boulevard in
