83rd and Spring Mill

83rd and Spring Mill is the intersection near which the swing set in Hazel Grace Lancaster's backyard is located. The address appears in the final line of the online advertisement that Hazel and Augustus Waters write together on the website Free No Catch, after Hazel has been crying in her backyard and Augustus comes over to comfort her. The ad, titled "Desperately Lonely Swing Set Needs Loving Home," describes the swing set as "well worn but structurally sound" and invites potential takers to make memories with their children, concluding with the line "Swing set currently resides near 83rd and Spring Mill." The intersection thus becomes the geographical marker for the object that symbolizes Hazel's childhood and her grief over her own mortality, and its inclusion in the ad marks the moment she decides to let go of that past. The ad attracts several responses, and Hazel and Augustus ultimately choose a man named Daniel Alvarez, who includes a picture of his three children playing video games with the subject line "I just want them to go outside." Hazel never sees the swing set again after it is given away.
