The Old Iron Bridge Centennial Film

The Pedestrian Bridge is considered Palmerston’s most unique and treasured
landmark. During the railroad’s peak in Palmerston, the Grand Trunk had expanded
the number of tracks in its yard to accommodate up to 40 trains a day. It became
very tricky to pass over such a large number of tracks without some inherent
dangers present. 

In the early days, a decision had been made to build the school on one side of the 

tracks even though the residential area was on the other side. As a result, all of the railway traffic had to stop to accommodate students travelling back and forth to school in the morning and afternoon. 

To minimize the danger for pedestrians, the Grand Truck Railway

began building the Pedestrian Bridge in 1910 which was finished by 1912. This
bridge allowed people to safely cross the train tracks and was often used by children
walking to school.

This bridge, constructed in 1912, has since been noted as the longest bridge of its kind in Ontario.
