La Paz runs the world’s largest urban gondola network, up to 300,000 a day above traffic; Mexico City, Medellin and New York run them as transit. A modern transit gondola is elegant; versions in development even roll the cabin off the cable, autonomously, to your neighborhood. Enclosed heated cabins arrive every few seconds, walk on, no schedule; one line moves 3,000 to 4,000 an hour each way. A new road scars the valley floor, so the Preferred Alternative paves a 122-foot freeway and 400-foot tunnel across 80 protected acres. One valley, one plan, one gondola.
