Many years ago Thruway workers put up 6 or 8 bluebird boxes, or maybe more, along the westbound lanes 3-4 miles before exit 29A.
When you enlarge this one you can see the Thruway emblem.
I imagine some guy building them either at home in his spare time or in the shop at the Thruway during the winter, and putting them up to add interest to the drive along this flat stretch of highway. Not to mention homes for bluebirds.
I haven't seen any being replaced, and the only one I could find to photograph is missing its roof. I believe there are 2 or 3 more remaining that are hidden by foliage right now. They are easier to see in the winter.
I hope this Thruway worker his enjoying retirement. He deserves it.
