Taking Cyclists Off Roads Is No Way to Improve Transit

London's latest overture for new cycling infrastructure might be its silliest yet. Just don't tell London that. Last week, the city gave the so-called London Underline the prize for Best Conceptual Project at the London Planning Awards.

A proposal from the global architecture firm Gensler, the London Underline would transform abandoned London Underground tunnels into subterranean cycletracks and pedestrian paths. The plan calls for reclaiming disused infrastructure, along the lines of New York's High Line or the proposed Dupont Underground in Washington, D.C. Plus, the London Underline would ostensibly provide a few connector routes for cyclists (and pedestrians, and even tourists).
