Mumbai to Combat Gridlock with Skywalks

It’s onward and upward for Mumbai. The tightly packed Indian city (population: 13,662,885) will soon be home to more than 50 “skywalks”—elevated sidewalks that sprout from the city’s train stations and allow pedestrians to avoid the traffic-choked roads, many of which are without sidewalks. “Skywalks are quick to build, relatively inexpensive, and only require land the city already controls,” writes Eric Bellman in The Wall Street Journal, which offers a wee stippled rendering of a skywalk along with photos.
