Construction of pedestrian walks is ridiculously simple in Florida. Scrape away a bit of the sod or ground cover, lay the wooden side forms, and pour concrete. No digging required. No deep gravel foundations. No frost heave.
The result is smooth, long lasting walk surfaces. The main hazards to a walk’s existence are tree roots heaving the ground, or heavy vehicles cracking the concrete.
Nonetheless, municipal maintenance crews must keep busy. Shown below are some sidewalk squares being removed and replaced for what in Ottawa would pass as inconsequential cracks:
The walks above are in Orlando, Florida. The area beside the walk had been freshly dug up by a utility, which accounts for the surface abrasions on the concrete, and presumably the cracks too.
