Bridge Documentation

This bridge was built in 1933 and is a rare example of a highway Baltimore truss bridge, and an even more rare example of a truss bridge with three truss lines in Canada. The use of a three truss line design allowed for a wider roadway. The third truss line, positioned in the center of the roadway, divides the bridge roadway into two halves. This bridge was reportedly built for  $70,864.07. The bridge was abandoned in 1964 when the Don Valley Parkway's construction cut the road off. A new Eastern Avenue Bridge that was compatible with the Don Valley Parkway was constructed some distance to the north of this bridge.

This bridge is located right beside the Gas Line Bridge, which is also a very unusual structure.

The previous bridge at this location was reportedly built in 1900 by the Hamilton Bridge Company of Hamilton, Ontario. This is based on a 1900 Toronto Annual Report of the City Engineer that states that contracts were awarded to the Hamilton Bridge Company for an Eastern Avenue Bridge. Its dimensions were described in this document as "132 foot span, 22 foot roadway, two seven foot sidewalks." Historical photos show the bridge as a rivet-connected double-Warren through truss bridge. A photo found in the City of Toronto archives and labeled with the date ca. 1890s may in reality by a ca. 1900 showing the bridge newly completed. At this time, the Gas Line Bridge did not exist, although sometime after the bridge was built, the first Gas Line Bridge (which a metal truss bridge) was completed. Reportedly, the previous Eastern Avenue Bridge was destroyed in spring floods in 1933, which prompted construction of the current bridge.
