The discovery of a 600lb bomb in south Armagh last week underlined the need for "a careful and controlled response," they said.
The police said they wished to thank local people for their patience and understanding during the operation.
Oliver Wilson, the manager of the nearby Share Centre, has offered shelter to those put out of their homes.
The alert has been condemned by the DUP MLA for the area, Arlene Foster.
"These are neighbours of ours and so, what we would say is, if any of those people don't have a home for the next night or so, until this matter has been resolved, we would be very keen to offer them whatever support we can.
"It is outrageous these people should be allowed to disturb communities going about their everyday business," she said.
"We would have accommodation here that we're quite happy to make available to them at this very difficult time," he said.
Local UUP councillor Harold Andrews was among those who had to leave their homes.
"There's a number of us along this road who have been out of our homes since this morning, and there is no indication as to when we'll be able to get back.
"There are farmers affected, including myself, and we would like to be able to get back to see to the stock this evening.
"People are very concerned, as the police indicated, but they can't take any chances.
"If a bomb was found that was similar to the one in Armagh, then these houses would be in danger," he said.

They said a search was necessary because of "a small number of criminals who appear intent on disrupting the lives of businesses and residents of the area".
