I’ve shared photos of this concrete road segment many times on this blog as a great example of early American hard pavement. It was probably poured in the early 1920s. But sadly, it no longer exists.
The 1910s and 1920s were a time of great experimentation as roadbuilders figured out that right intersection of road-surface durability and cost. This was the era of brick roads, but builders also experimented with asphalt and Portland cement concrete. Early concrete roads were continuous ribbons. Natural expansion and contraction caused the concrete to crack, and often to crumble. This photo shows this road’s crack pattern better:
Roadbuilders soon figured out that regularly-spaced expansion joints helped concrete roads last longer. My experience has been that this happened by about 1925. Continuous concrete roads were built for a short time in modern road history, and most concrete roads will have expansion joints. When you come upon a continuous concrete road, you’ve found a rarity that is nearly a century old.
You can thank the construction of I-69 for this segment’s destruction. This road was a segment of old State Road 37 and the Dixie Highway, about five miles south of downtown Martinsville. Modern SR 37 has bypassed it for years, mere feet to the west. As the modern road is upgraded to Interstate standards, an exit is being built here. The plan maps (here and here) show the details. This map segment is from the old Windows Live Maps site; I captured it in 2007 when I wrote up my first trip along this old road (here). This concrete is the segment labeled W Hacker Creek Rd north of Liberty Church Rd on the map. The section south of Liberty Church Rd had been covered with asphalt. I made these photos from the north end of the road, where a bridge had been removed.
I have no photos from my recent trip along this road because the exit here is substantially complete and construction closures and restrictions blocked access. As we moved past here on the new highway I could see a ramp exactly where this concrete used to be. A new bridge was even built over this gap.
And it’s too bad. I’m sure people who live down Liberty Church Road will be happy for easy access to their properties from I-69. But they get it at the cost of losing an interesting and well-preserved example of road history.
Old bridges and old buildings are obvious choices for historic preservation, especially when they are of a style or type of dwindling number or are part of a historic resource. But I think old pavement should be as well.
Just like any candidate for preservation, you can’t save them all. But I’m pretty sure this was the last section of continuous concrete highway on Indiana’s Dixie Highway, and as such this destruction was a real loss.
