#80: CLEANER AIR ON THE BACKSTREETS. Even if all the main roads in London were flanked by segregated cycle lanes (which is never going to happen), there would still be plenty of reasons for cyclists to prefer the quieter routes represented on the London Cycle Map.
For one, you can’t separate cyclists from the thick black fumes spewing out of the buses and lorries that chug along London’s major highways: the only way to avoid the worst pollution is to choose less busy streets.
On the tree-lined suburban roads of the London Cycle Network the air quality is noticeably better, which maximises the health benefits of city cycling. By making these routes easier to find and follow, the London Cycle Map would make cleaner air easier to come by.
