The story was predictable and typical of the 50's. However, I would have let Granny sit out by her trees for a few hours until she wandered back inside before I told her that the bulldozers wouldn't be there for a couple of months.
The innocent optimism of the time and callous disregard for nature is very typical of the Eisenhower Era. So is the presence of only white faces. Another nice touch is the formal dress worn by just about everyone and the acceptance of the judgement of the highway department.
The speech at the end about the common good and the defense of the country (presumably against Communists or anyone who drove something not built in this country) was a nice touch.
