Spots like this, where the sidewalk curves in to avoid an obstruction that is no longer present, are fairly common, but I notice them every time. I always wonder what was there and how long it’s been gone. I usually figure it’s a tree (because I have seen spots where the sidewalk does curve just like this for a tree), although this would be a somewhat odd placement for a street tree.
The driveway apron used to be narrower, as I can see from an old tax assessor’s photo, so apparently when it was widened the contractor added a little piece to fill in part of the semicircle.
This bit of sidewalk is on the north side of Hickory Street between Pennsylvania and Euclid. I walked this block for the first time this evening, so get ready for several days of Hickory photos.
