Circular Runways

So cool. Not sure what the practical concerns of this are, but it’s a really fun idea to consider. Less noise, fewer crosswind concerns, efficient use of space. What’s not to love?

Looks a little odd, and I wonder if it’s more of a pipe dream than a practical solution, but I’d love to see this implemented somewhere. I can’t imagine taking off or landing on a banked surface though.

On Grids: Denver

One of the things I’m most interested in is the story of how cities and other developments were built the way they were. Grids, I think, are a great at revealing these stories. While they’re intended to give a sense of rationalism and logic to city structure, North American city grids still have many quirks. These are what make them interesting. An endless sea of square blocks in every direction sounds oppressive.

If you look closely at any city in North America that’s based on a grid, you’ll find inconsistencies, winding roads and other oddities. Or, in some cases, you’ll find competing grids. Denver is a great example of that.

Settled in the 1850s at the confluence of the South Platte River and Cherry Creek, it would later become a major metro area and the heart of the Front Range Urban Corridor. Denver’s original grid was designed as a set of diagonals1. It was actually founded shortly after Auraria2, which was settled immediately to the west, across Cherry Creek. Their grids actually (almost) align. You’ll find a slight wander in the streets, and a more in depth explanation here.

As time went on, the rest of metro Denver was developed in accordance with the Jefferson Grid 3, or the Public Lands Survey System (PLSS). Because of this, you’ll see that Denver’s downtown grid clashes with the North/South orientation of the PLSS. You can see this especially where Colfax and Broadway intersect near the capitol.

You can see Denver’s original grid clashing with the PLSS. To the northwest, it dissolves into the developments along the South Platte River and Interstate 25.

This comes at a cost, with confusing five way intersections, and other inconsistencies. Despite that, it’s these developments that can give a city character and history. It breaks up the monotony of a perfect grid, and if anything, can give a city imperfect, human qualities. But, zoom out beyond downtown, and it’s obvious how much the PLSS shaped the rest of metro Denver’s development patterns.

How streets, roads and avenues are different

Having grown up in the suburbs, my recollection of street names boils down to an assortment of roads, lanes, circles, etc. Add to that the naming of subdivisions after what seemed to be random pairings of words like oak, birch, hill, ridge, and others, I figured there was no logic to it.

Thanks to Vox (they make great short explainer videos), I now know that there is a logic  behind the sort of street. Sure, in cities like Chicago there is a very rational system for street names. But in the suburbs, I thought it was mostly nonsensical. I’m sure in some places it might be, but I love hearing the reasoning behind the types of streets. Enjoy.
