Do you have a local box turtle group that would know about the area under construction, that might have a plan of attack so to speak about what to do with a displaced turtle like this one?

My feeling would be, if there is one strip of woodland or natural homeland left, you have to release it there and hope for the best. Maybe you could give her a good meal when you put her back, so she won't venture out into the construction area again? Not sure. Moral dilemmas abound. That's my two cents. Keep us posted.
