When did paved asphalt roads become commonplace?

And why Meridian Twp is called Meridian Twp. But also, it’s kind of neat how the townships fill in a county, and how the counties are aligned.

Other than Detroit which road alignment predates the PLSS, it’s almost a sure thing that non-grid-aligned roads are old Indian trails. Moravian comes to mind, and of course Pontiac Trail. Of course the Mile roads and the meridian roads (Kelly, Garfield, Hayes through Beck, Wixom, Napier) are on the grid, too.

It’s why farmland is 20/40/80/160 acres, and why a subdivision is called a subdivision.

It’s a pretty cool system.

When I lived in Valparaiso IN, Lincoln Hwy ran right through the middle of town. I recall a monument to the portion of it that was paved as an “ideal section”, completed in the 1920s. Here’s a pic of a monument in a neighboring town.

If I’m ever in the area, I’d love to make a trip to see the beginning point! Just to see where it all began. Love the idea of these surveyors hauling their chains across the wilderness! :smiley:

I may have to bookmark this. Thanks.

The mid 1920s is when you started to be able to travel substantial distances on concrete, and by the early 1930s or so where it was rare to have to travel on gravel between major cities. Asphalt was about that time and was originally a thin layer over gravel and was considered an improvement over gravel, but not in the same league as concrete. The Minnesota highway maps of the day used to distinguish between asphalt roads and concrete roads. Eventually the symbols morphed into a more vague “high type” and “intermediate type” and persisted up to the 1990 edition.

There were still a few sections of roads in Little Rock with gravel over a hard surface in 1980. I don’t think it was dirt.

I lived near the intersection of 36th street and Shackleford Rd. That section of Shackleford was gravel for about three miles then it switched to asphalt.

That’s a trendy area now packed with shopping centers and heavy traffic.

I remember a few other similar areas of road that were primarily asphalt but switched to gravel in undeveloped areas of the city.

That’s on my pilgrimage list, well, as much as I can be a pilgrim as long as I’m in the area and it’s convenient.

Note that in some places a dirt road and a gravel one are both called dirt; in other places the difference is significant. The gravel they use in Kansas is much softer than the shale gravel in NY. I’ve heard it claimed that a paved road is cheaper to maintain than gravel, which needs to be replaced and graded frequently. I was told that a rancher in western Nebraska paid for the US highway across his ranch to be paved so he could get around on his own land. This was after WWII. A contractor I once worked for said that asphalt cost one-third the cost of concrete, and lasted one-third as long. He was talking driveways.

At least for heavily trafficked highways, the battle between asphalt and concrete continues. Studies simply don’t seem to offer a clear conclusion about which is the better long-term choice.

Concrete paving was traditionally seen as the more durable choice, but the New Jersey Turnpike was entirely asphalt—and that lasted more than 50 years with little deterioration.

The surface layer gets the attention, being visible, but the quality of road greatly depends on the roadbed. That’s what supports the surface and protects against undercutting, subsistence, and heave. We’ve all seen concrete sidewalks destroyed because of a poor bed, the same happens to roads.
