Every now and then somebody comes forward and proposes an urban gondola. The most recent one that I have heard about here in Toronto was this one from 2016 called the "Don Valley Cable Car." But like many gondola proposals, it sort of just disappeared. Probably because it wasn't entirely necessary. (I just checked their website and it is now down.)

However, there are rare instances where a gondola makes a lot of sense. Medellin, for example, has a very successful urban gondola system that my friend Alex Feldman wrote about, here on the blog, after a visit to the city back in 2014. In this case, the gondola was instrumental in connecting hill-side communities that were previously disconnected from the rest of the city.

Another less urbanized example is the one that Utah (Salt Lake County) is planning to build in Little Cottonwood Canyon. I wrote about this project back in March when I was there and, today, the Utah Department of Transportation announced their preferred mobility option. It is called Gondola Alternative B and, as far as I can tell, it is still the longest and most expensive urban gondola ever proposed.

Here are the details in graphic form:

To summarize, though:

• The system is being designed to carry 1,050 passengers per hour, with cabins departing every 2 minutes.

• The gondola itself is expected to cost $370 million, but when you add in a new parking garage for 2,500 cars, tolling infrastructure on the existing State Route, and other improvements, the total all-in capital cost is projected to be $729 million. The route itself is somewhere around 10 miles, so let's call it $73 million per mile.

• At the same time, the projected operating costs are relatively low at $8 million per year, so this option actually has the lowest 30-year lifecycle cost out of all the ones that were studied. The other alternatives included widening the existing roadway, enhancing the bus service, and adding rail. There was also one other gondola option, which was presumably called Gondola Alternative A.

If you're wondering why this is likely a good idea, check out my post from this past winter.
