A few cities (mostly in South America) have recently built or are planning to build gondolas to lift people up and over traffic to take them throughout the city as an efficient, low(er) cost, and scenic means of public transportation. This is the second time I’ve run into this urban mobility solution in the last couple of weeks and given how successful some of these projects have been, I’ve been wondering why it has not yet been more widely implemented. Compared to the disruption and all the technical difficulties in digging tunnels for underground metro systems, building these hanging subways is far less disruptive (and cost “between $3 million and $12 million per mile, comparing favorably against $400 million per mile for subway systems and $36 million per mile for light rail systems”}¬†and although they don’t have the carryings capacity of underground trains, they can be visually “timed” and offer a visible link to the heart of the city for residents of historically marginal areas (or “urban islands”) that are then connected to gondola lines. The article claims that plans for a gondola system is in the works for Lagos (I’m not sure if it’s part of the proposed but slow to develop plans for a Lagos train metro system). This is a phenomenon worth following.

A great blog post on Nigeria’s plans to build a new centennial “smart” city (more of a district) for 100k people in its capital Abuja (itself a planned city that was built in the 1980s). While praising the socially and environmentally conscious planning approach that promises “a mature vibrant ecosystem,” the piece reminds us that new cities in developing countries are almost always reliant on fickle market driven investors hoping to reap huge economic playoffs from these “green and sustainable” international business hubs by quite simply plundering its countryside. These ambitious, environmentally conscious, new city projects are in themselves fantastic examples of planning and social responsibility, but as the post points out, at some point we have to take a step back and question whether our capitalist economy and its byproduct of violent ecological damage are themselves sustainable, and how do we plan and build a better version?
