park on the driveway.
Everyone knows that sidewalks are poured concrete.
We’ve chronicled that process here:
But do you know what’s underneath?
Those metal doors give access to a large,
empty void down there.
It’s hollow, enlarging the cellar.
So they bridge over it with steel.
But time and rain and road salt really take a toll.
So they replace the steel beams now and then.
Bricks and mortar help stabilize,
...until the steel is locked into place.
So keep in mind it’s often hollow underneath,
inside the curbline.
And in winter when it’s already under snowload?
