There is a hole the size of a woman's small shoe in the sidewalk on Broadway in front of 2820 Broadway (a Hyundai dealer). This hole is actually in metal doors imbedded in the sidewalk; it's perfectly round and appears to be intentional. However, it presents a hazard and can trigger and fall that is certain to cause serious injury. Any pedestrian can trip there, but there are three buildings with 700 senior residents around the corner and use the sidewalk to get to local businesses.
