According to the Knoxville News Sentinel a bridge connecting greenways on both sides of Alcoa Hwy (US-129) was put into place Sunday. Plans call for the bridge to be opened in early December.
Alcoa Highway is a high-speed road that's notorious for car crashes, and having a way to safety cross it is an improvement. Perhaps more importantly is the fact that neighborhoods will be linked to the Blount County greenway system that were previously separated by the road. For transportation infrastructure to be functional and useful, they have to go to enough places that people want to go; network breaks are highly destructive. Hopefully we have just eliminated one such break in the network.
