    Has anyone put in a rock Cannolis on their dirt road? If so, does it come up from the ground during frost heave season?

    does anyone have a dirt road?  if so, for cross road drainage, have you put in a rock canoli? please reply your experience with it as to it's maintenance, verse the issue of expensive culverts, and it's maintenance if not the added repair to it's  damages.

    A rock cannoli is only appropriate where there is a slow weep coming out of the soil and under a road, that you need to keep from building up.  (You can use several at intervals if needed.)  If there is an actual surface stream, you need a culvert.  A cannoli will catch too much leaf trash etc if there is a real stream, and also it will block passage of fish etc.  A cannoli can freeze and heave, but generally not as much as a culvert.  It works very well where appropriate to keep water seepage from building up and saturating the road, and it's cheap because you can use local rocks to fill it.
