Why do sidewalks have blocks, instead of being solid?
In: 205
Sidewalks flex, get pushed around by trees, crack, and need to be replaced. If the sidewalk was solid for the whole city block and it got a bad crack halfway down, you’d have to either replace the entire thing at once or cut into the existing concrete to replace a smaller section, like a “block.” But since they already do blocks, they can only replace the damaged or heaved parts of the sidewalk.
They replaced our sidewalk last month and they only did the damaged bits. They’re not planning to revisit the sidewalk on our street for 15 years. The ones that are fine, flat, and not cracked or damaged they didn’t replace, saving us money.
