The lane will extend from east to west London, with another north-south route in the works as well. According to The Guardian, the project is part of a larger citywide initiative for biking that will cost upwards of a billion dollars (£900 million) over the next 10 years, and will stretch approximately 18 miles directly through the center of London. Other segregated bike paths have popped up near London in recent years, but a route of this magnitude in an urban environment is unprecedented.
