"Aerial cycle highways for London"

"Sam Martin, director at Exterior Architects, says new space needs to be
found for cyclists. His Skycycle idea is for a network of elevated
routes that would run over Network Rail train lines.

"Bikes would remain on the roads but SkyCycle will bring in a new type
of cyclist - people who want a direct route into work and those who feel
unsafe cycling on busy London streets.

"The highways would be 14m wide, accommodating three or four cyclists
abreast in each direction. Lifts and ramps would get cyclists up to the
cycleway.

"The first route to be planned is a 6.5km artery from the Olympic Park
at Stratford in East London to Liverpool Street in the City. It would be
able to deliver up to 5,000 cyclists an hour in and out of central
London and would cost about £200m to build, Martin predicts."


So far... so good...

But...


"It sounds a lot but compared with Crossrail is cheap, he argues. The
scheme would be operated by Transport for London with cyclists paying by
Oyster swipe card...".


Ah well... it was a good idea for the few seconds it lasted before
sliding into surreal fantasy.
