Crossing Pompeii—Without the Mud
Step into Pompeii and you’ll see odd stone blocks sticking up in the middle of the street. These are not debris or ruined columns—they’re crosswalks.
Roman Engineering for Dirty Streets
Roman street crossings were built high for a reason: city streets flooded with rain, animal droppings, and sewage. The raised stones let people walk across without dirtying their feet, while gaps allowed carts to roll through. The wheel ruts, still sliced deep into the basalt, show just how often heavy wagons thundered by.
Romans designed their city streets with traffic-calming blocks: giant stones set at intervals so pedestrians could cross without stepping in filth, but carts could still squeeze between them. Grooves carved by thousands of wooden wheels are still visible between the stones today.
