Vexing question of the day: What’s the deal with those stumped-off sidewalks on many corners of the new, improved and almost completed Skillman Avenue redo below Mockingbird? I’m enclosing an embarrassingly poor camera-photo of the one of the corners (note my Grinch-inspired, pointy-headed shadow?), but you can see what I’m talking about: The now-handicapped-accessible intersections have sprouted little sidewalk connectors to nowhere. I asked Angela Hunt about the deal, and she quickly referred me to someone at the city, who I have yet to hear back from. But here’s my guess, knowing that the city doesn’t have money to add sidewalks there on Skillman and knowing that neighboring homeowners aren’t going to be passing the hat at their association holiday parties, either: I imagine that as part of the Americans with Disabilities Act (ADA), the city was required to make the intersection accessible for wheelchairs and, in a move fraught with foresight, decided to go ahead and build the sidewalk connectors, too, just in case. When and if the definitive answer comes in from the city, we’ll post it.
