Blair Railroad Bridge
When the bridge was rebuilt
in 1923, the old superstructure was removed and replaced in
stages. The westernmost 330 foot truss span was replaced
first. In this view, which was taken about mid-November 1923,
the new west span was already in place, and the original east span,
on the far right, continued to carry traffic while construction of
the center span proceeded. The old center span has been
removed and false work consisting of framed bents of piles supported
the deck and track where the two cranes were beginning the erect the
center span. Although the locomotive cranes had to occupy the
track in order to erect the new superstructure, interruptions to traffic
were kept to a minimum. The cranes were regularly moved off
the bridge and placed in the clear except for two longer periods
when traffic was suspended for about 17 hours. C&NW photo,
