One of San Angelo's marketing slogans is "The Oasis of West Texas". This is not hyperbole; most approaches to the city are somewhat stark, so in contrast upon arrival in Angelo, one may well be pleasantly surprised at all of the rivers, reservoirs, trees and other vegetation:
One of the city's other monikers is "The Pearl of the Conchos", which has a double meaning, referring to the freshwater Concho pearls that were historically harvested from area waterways. The three branches of the Concho River all converge in San Angelo; that was illustrated on this other slogan from days gone by:
When the US highway system was inaugurated in late 1926, the only US route to initially serve San Angelo was US 385 (that is, the original US 385, not the current US 385). The new designation was added to Texas State Highway 9:

Of the "main" US highways (i.e. the one- and two-digit routes), the longest nine were all east-west routes (6, 20, 50, 30, 40, 60, 70, 80, 12). And if we take the longest 16 highways, only one of them is a north-south route (US 1, shown in red here):
That stands to reason, because the United States is roughly twice as wide from east to west as it is from north to south. So it makes sense that there would be more long east-west routes.
