There are 3 wooded lots (3 different owners) next to us and our subdivision and on the other side is a very expensive (lots/homes) subdivision. The other subdivision was upset about new homes (inexpensive and smaller) being built next to them and they wanted the street out front to be widen to handle more traffic, etc....), anyway be the time the street was widen, new sidewalks along the street widen and two circles ("round-abouts) put in, the developer ran into money problems and nothing happened.
Originally, when and before we built here, the developer for our subdivision wanted to extend our subdivision, so that's why we live on a stub street and not a cul-de-sac. The connection would've been in front of our house and yard. Hope it never happens.
