The Bridge Builder is a minor character in that lives alone in an isolated abode within the Snow Realm. In the absense of an actual name, his title operates as a satisfactory description of his mainstream work. Like many characters and objects in Spirit Tracks, the Bridge Builder is a Chekov's Gun, as his services are not necessary, or even significant until later, once Link meets with Linebeck III, at the Trading Post.

At the Trading Post, the Spirit Tracks that once smoothly ferried passing trains past this station had fallen under dilapidation, and are in need of immediate repair, if Link is to continue his adventure. Linebeck III suggests that Link find a birdge builder that can repair such tracks and get them both out of such a predicament. Link locates the Bridge Builder in the Snow Realm, who agrees to come down to the Trading Post with him on his Spirit Train, under the condition that Link obey the speed limits and signs scattered about the Spirit Tracks, and that he not only arrives safe and sound, but precisely at the station, as well. The Bridge Builder surveys the damage and agrees to take on the job, for a steep fee of 5000 rupees, a price that includes this job and any other previous debt Linebeck has carried over from previous encounters with the Bridge Builder.

After locating the lost heirloom of Linebeck Senior at the rear of the Trading Post, the Bridge Builder completes his work. In payment, the Bridge Builder takes Linebeck Senior's treasured Regal Ring (estimated to be worth 8000 rupees) and goes on his way, without giving Linebeck III or Link the remaining 3000 rupees in change they would have recieved if the payment was in rupees alone.

Trivia

 * Interestingly, though Link ferried him a long ways to the Trading Post on his Spirit Train from the Snow Realm, he does not require a ride back.
