Bridge Documentation

This bridge has been altered, resulting in a severe loss of historic integrity and significance!

Bridge Status: Original railings have been replaced!

Information from Ontario Bridge Inventory: Bridge width: 10.4 meters.

The 1959 construction date is an assumed ca. date based on known dates for area bridges on the 401.

This bridge is one of a couple overpasses on this section of the 401 that offer a double-span configuration instead of the single span design that was originally found elsewhere on the 401. The two-span bridges have a more shallow arch shape.

This bridge was being rehabilitated when photographed. At the time it was photographed, it still retained its original railings, something rapidly disappearing from the few original 401 overpasses that are not being totally replaced.
