D.C.
I know where you mean, and I have a friend that lives in a very nice family neighborhood in that area. If you put Darlene Drive, Corapolis, 15108 into mapquest, and then look at the a wider view, you can see that there is a triangle made by routes 376, 22, and West Allegheny Roud. In this area, there are a lot of roads ending in cul-de-sacs. These are all nice family neighborhoods.
BTW - some people are confused because 376 in that area was very recently renamed. Until about a year ago, that part of the highway was 279. You are correct that it is 376 now, but to avoid confusion, you should just tell people your husband is working off the 22/30 exit of the Parkway West. That is what we Pittsburghers call that part of the highway :)
