About This Bridge

As of August, 2015 when this bridge was added to HistoricBridges.org, information and photos of this bridge on the Internet were nearly non-existent. One of the reasons might be because to see the impressive structure you have to venture under this bridge, perhaps using the trailway that follows Yellow Creek under this bridge, and you would need to do so during a time when the leaves are off the trees. Otherwise this bridge (which is buried in the woods) would be nearly impossible to see or photograph.

Hopefully this page will inspire greater awareness and discussion of this bridge. This bridge is in fact one of the most impressive bridges in Toronto, and should be considered a heritage bridge of high significance for its uncommon design, and excellent historic integrity due to lack of alteration.

The bridge consists of an impressive main steel deck arch span of roughly 94.5 meters (estimate) and with a substantial height above the valley floor. This span is a single hinge arch design, with the crown hinge at the center of the span clearly visible. The arch consists of three ribs. Ribs, members, and bracing are riveted built-up beams and include v-lacing, lattice, and battens.

A short series of steel deck plate girder spans form an approach at each end. These approach spans include arched fascia girders for aesthetic treatment, and their design appears to be concrete encased steel girders.

Previous Bridges At This Location

The existing bridge is apparently the third at this location. The previous bridge is documented in several historical photographs shown and discussed below. It was a beam or girder bridge, supported by riveted steel bents, sometimes called "towers" as the design was called by railways (who often used this design to span valleys) the "tower and girder" style of bridge.

The above photo, dated 1907, shows the deck of the previous bridge, including its ornamental lattice railing.

This 1915 photo shows the previous bridge from the valley below.

This 1927 photo shows the demolition of the previous bridge as part of the construction of the steel arch bridge.
