I stood on the high line here salivating. Sydney, here is a mega city and even they have managed to go on a road diet. A road diet in NYC looks like a lane for shared bikes, a bicycle lane, pedestrian crossings at each and every leg of the intersection. And signal phases that don't force you to sprint across as soon as the pedestrian light goes green just in case you get stuck a quarter way across and people try to run you over.
I was on my way to meet my friend in Brooklyn and what do I see when I walk out of the subway station, walking along the pedestrian overpass, over 8 lanes of traffic? A beautiful separated bi directional cycleway and footpath running down the middle of the chaos buffered nicely by trees and parked cars.
That's actually not Penn Station. The station is behind me in the photo and unfortunately the original station was knocked down to make way for Madison Square. This building is actually the post office and was built to complement the station.
