I have seen this more often then you think. The road probably was only 1 lane per side with no sidewalk originally. When the road was widened and the sidewalk built, this is what was left. The owner should have been compensated for the loss of utility for the garage along with the loss of the land between the building and the original lot line. If you travel just south of Indianapolis on I-65 you will see a storage facility with a row of garage doors that open to the fence along the highway right of way. The building was built before the exit ramp was reconstructed. The mini warehouse owner probably took the divider wall out and made bigger units accessible from the other side. Of course he would have been very well compensated by the State of IN. In the picture, the unit would now be considered a storage area not a garage, it may be accessible from the adjoining unit on the inside but you cannot see that.. It is a neat picture that certainly makes you think.
