In the heart of Texas, a testament to engineering longevity can be found on State Loop 442. This Limestone County road, running through the historic town of Tehuacana, boasts an almost century-old pavement that has remarkably been laid only once. The concrete, poured back in 1929, still underlies the loop today, according to the Texas Department of Transportation.
With regular inspection and minor repairs, engineers have managed to quickly sustain the road well past its expected lifespan. "The pavement core is from a jointed reinforced concrete pavement," said TxDOT's Waco District pavement engineer, Mark Davis, to TxDOT. With its cross-section revealing very little distress, "We haven’t done any major work [to Loop 442], just minor patching," added Roger Brooks, TxDOT Limestone County maintenance supervisor. Despite a daily traffic count between 150 and 350 vehicles, significantly less than the adjacent SH 171, this roadway stands as a proud piece of Texan history, as per the Department of Transportation.
Through its fluctuations, Tehuacana's story is built around its community spirit. "This town used to run almost all on a credit basis; you’d go to the grocery store, everybody would have their ticket, you pay it every month," recounted Doug East, a former mayor and resident of Tehuacana, in a TxDOT interview. Mayor Janis Johnson encapsulated the town ethos, saying, "It’s a small town, where it’s family. You did have a lot of aunts and uncles who raised the community." The town, albeit small, still hosts key amenities like a city hall, churches, and a volunteer fire department, intertwined by the old yet sturdy pavement of Loop 442, reported by the Department of Transportation.
