Four interpretation panels tell the story of early air travel. In the days before two way radio communication was prevalent, these concrete shapes were used as navigation aids to pilots carrying airmail across the country. Each arrow was assigned a tender, and each tender was responsible for making sure the light that was associated with each arrow properly lit the way. This is a fee-free site. This site is ADA accessible and includes interpretation panels in Braille.
Take Interstate 80 west to mile marker 120 Superior. Go North one tenth of a mile; head West on the Superior Mail Access route. Stay left at the fork. Travel West three miles.
