In case you haven't been that way recently, there is a road closure at the intersection of 107th and Prospect for utility work. It looks like a Water Dept. project and is likely to take a while, depending on weather.
There's detour signage in SOME places, but they neglected to put any on southbound Prospect. Some geniuses driving south on Prospect decided it was okay to drive across a couple of lawns to go from Prospect to westbound 107th. Who does that?
I would encourage you to contact the ward office and demand that detour signage be put in place on southbound Prospect. Here's a link.
I'm not sure if eastbound 107th needs detour signage between Longwood and Prospect, as I haven't gone that way since the construction started. If you're familiar with current conditions there and can confirm that there is no detour signage for eastbound traffic, please leave a comment, and please tell the ward office that this is NOT acceptable. East Beverly and Morgan Park deserve the same level of service as the rest of the ward.
