Check out this article from City Journal about elevated bicycle lanes. For Toronto, maybe these elevated lanes could be designed to run along the LRTs or John Tory’s Smart Track system?
Other cities think big. In London, famed architect Norman Foster has proposed an ambitious, 136-mile elevated bike path, to be suspended above the city’s suburban rail network. Foster’s “SkyCycle” plan—which could accommodate 400,000 bike commuters daily—has the support of former mayor and potential Conservative Party leader Boris Johnson, as well as the local government agencies responsible for London’s public transportation system. Architect David Nixon envisions a floating bike lane in the Thames River that would allow a car-free commute from the city’s residential areas to the financial district.
In Melbourne, Australia, a consortium of investors has proposed attaching an enclosed, mile-long “Veloway” to the side of an existing rail viaduct running through the city. “[C]ars, bikes and pedestrians just don’t mix well,” Committee for Melbourne CEO Kate Roffey told a reporter earlier this year. “This would solve the problem of separating cars and cyclists moving east-west across the city, and pedestrians can go under or over roads.” A similar approach would seem well suited to New York’s outer boroughs, where, unlike midtown Manhattan, elevated rail viaducts remain the norm. Many commuters in Brooklyn, Queens, and the Bronx would likely take advantage of an option that would get them from home to work in about an hour, safely and free of charge, with a little fitness thrown in.
In Denmark, bike-friendly Copenhagen cut the ribbon this past summer on its Cykelslangen, or Cycle Snake—an elevated lane providing cyclists with a much-needed traverse over a pedestrian-heavy corner of the central city. “It is one of those rare occurrences in Copenhagen where seemingly everyone is happy,” wrote Classic Copenhagen blogger Sandra Hoj. “Cars have not had to budge an inch, the lower level has been returned to pedestrians, and cyclists love it. Besides easing the transition from highway to bike bridge, it is a pure joy to ride.”
