For keen cyclists, building a series of cycling superhighways that link outer London with the centre is a no brainer:
They mean people can commute to work more safely in less danger of being hit by a car on the many thunderous carriageways and gyratory systems that link up the capital.
They also help to improve people’s health and start to shift drivers and families away from relying on the motor car.
Of course not everyone agrees. Some feel the superhighways – which are basically two-way cycle lanes protected by kerbs – will wreck the pavements for shoppers and shopkeepers, make it more difficult to get in and out of junctions and slow traffic down on major routes.
I decided to see for myself, so on Tuesday, August 7, members of the Hounslow and Hammersmith and Fulham Cycling Campaign groups took me on a ride on a Boris bike along some of the proposed route of Cycle Superhighway 9.
This planned linked between Hounslow town centre and Kensington Olympia and will cost Tfl a cool £70 million to put in place.
Needless to say it has been Marmite so far, dividing local councillors and residents like a knife through butter.
