It can often be difficult to figure out extactly where a given road used to run, especially given the huge changes made so easily to the landscape by modern earthmoving equipment. A little while ago, I stumbled upon something so obvious that I can't believe I didn't think of it sooner: utility poles.
Utility poles often follow roads. However, when roads are rerouted, utility poles often remain in the same location. By looking for utility poles, one can often find fugitive older alignments.
