I saw this IRL and did an actual double-take when I realized it was open-wire telephone (telltale conductor transposition pattern: <https://the-electric-orphanage.com/wp-open-wire-transpositio...>) and not an old railroad telegraph line like can be commonly found.

Honestly shocked that any of this is still standing. My pics: https://ibb.co/album/vhrp2x

“Beginning in the summer of 1942, the Signal Corps installed an open wire telephone line parallel to the Alaska-Canada Highway that was being constructed to connect military airfields and enhance the defense of the territory. Using mostly commercial crews, it was completed in just 15 months, despite requiring the setting of 95,00 poles in frozen ground and the stringing of 14,000 miles of wire.”
