Bridging The Gap

Jamestown Line Bridge - Builder and construction date unknown. Although the design is found on multiple bridges in Ontario, outside of Ontario the design of these bridges would be classified as extremely unusual and rare. Two elements make the design unusual. First, the truss configuration is a subdivided double-intersection Warren. This means that in addition to a vertical member between each "X" of diagonal members, there is also a vertical member that passes right through the center of each "X." Double-intersection Warrens are uncommon, but subdivided double-intersection Warren truss bridges are very unusual. Thanks to Historic Bridges for the above information

  2. That is a lovely bridge with a lot of information about the construction. Had to ask hubby what an intersection is, but now I understand :) (Thanks for the funny images in your comments, I like them!)

  3. A lot of information Andy. I also see that the height is now given in m and not in feet anymore.

  8. This is a beautiful bridge and I really appreciated your commentary. The wooden boards look a bit worn, though, and might need to be replaced. The overall, it looks quite sturdy and safe.

  9. A very cool old bridge! I'm hoping this is a one-way only road. It would be tough to have to back up if traffic was coming the other direction!

  15. Great shot! How I would love to drive over that wooden bridge. The sound takes me back to my childhood and sadly many of Australia's wooden bridges have been replaced.
