We had some field staff have a problem installing a steel traversable culvert grate on a concrete pipe (see photo).
We and a number of other states allow the use of an adapter to connect the steel traversable culvert grade to concrete pipe.
I was wondering if MwRSF has seen similar problems in the past or has come up with other possible solutions (e.g. traversable concrete grate comes to my mind...).
I know that the 4" object standard is difficult to apply on a slope, but it is the best published guidance I know of
