Here is another module design this time a road including left turn, right turn, T intersection, and a four way intersection.

A sewer that uses Hoppers is included (You may need to face them the right way depending on which way you want the sewer to flow)

Modifiy it to suit your needs and if you post it as part of a build, youtube video or such please link back to this page and give credit and also leave a link for me to how you used this so i can check it out.
