Sewer construction?

I do not travel by the intersection of SR 114 and I-65 too often, but a couple weeks ago I noticed digging equipment there. On Friday the workers were working on something sewer. I assume that this is the start of the sewer-line extension project. If you know that I am wrong, please correct me in the comments.

This picture was taken from the parking lot of Kentucky Fried Chicken, looking north across SR 114.

The contractor is Grimmer Construction from Highland, Indiana.
