Construction progress report

The road to success is always under construction. Well maybe not always, but it can seem that way. We understand that all the recent roadwork in the Cumberland Improvement District has been an inconvenience. But, progress is road constructionbeing made, and when it’s finished it’s going to make travel through the area much easier.

We want to give you as much information as possible to help you navigate some of the tough spots.
