borrow pit; barrow; bar pit noun in rural western Canada, the pit from which earth is being removed for construction purposes CANADA
In some cases it is, in fact, only borrowed and returned later as would be the case when building temporary dikes during spring flooding. However, it is still the borrow pit (or barrow, or bar pit) when the earth is gone for good. Often the road ditch. — Chris Thain, ColdasaBayStreetBanker’sHeart, p. 9–17, 1987
