There are a number of important details to note on the Fourpoints Bridge. To aid in this discussion, the diagram on this page serves as a guide and key to the text that follows. First and foremost is the caps on the endpost / top chord connection (B). These caps are cast iron and display a patent date on the front and a decorative star shape on the side. They serve both an aesthetic and functional purpose, covering up and protecting the unusual connection detail at those locations, a connection detail which Wrought Iron Bridge Company would use also in its pony truss bridges such as Smith Road Bridge. The nature of the connection can be seen in that Smith Road Bridge because the pony truss bridges did not feature caps, so the connection is exposed. The detail is visible on Fourpoints bridge from below as seen at (E) in the diagram. Instead of having the diagonal and hip vertical members be an eye bar to fit around a pin, they are threaded at the rounded end and large bolts hold it in place at that connection. The thinking behind this connection is also visible with the end post / bottom chord connection (C). The lower connection of the hip vertical (G) was another place where the company often used an unusual design. This was typically an strange four-pronged/looped eye that attached to a hanger loop on the floor beam. At least part of this connection has been altered with the flooring system replacement on Fourpoints Bridge. The actual vertical may represent the original design (and perhaps materials) however, but if this is the case, than this bridge displays a more standard eye shape at the end. Another unusual detail is the presence of a very lightweight rod that runs the length of the truss (A). This rod is seen on other early bridges by the company, and its purpose is unknown. It may have been an attempt to provide additional stability to the truss. No other prolific bridge company appears to have placed such a rod on their bridges. Compared to other pin-connected truss bridges, their is a lack of v-lacing or lattice on the bridge. This is again typical for an early bridge by Wrought Iron Bridge Company. The company instead used either rolled beams, as seen in the sway bracing, or their built-up beams such as the vertical members (D) were small and relatively lightweight and as such their design did not have room for or require large lacing and lattice to hold them together. Finally, the observant visitor to this bridge may notice, particularly on the cast iron elements of the bridge, that there are numbers on them (F). These may have been originally to aid in bridge assembly.

This bridge looks too narrow.


I think I found the tag. It's north of the last one.
+39 42' 50.24", -77 12' 56.43"

I don't think it's on Bridgehunter.

I came to the same conclusion yesterday. Based on the house in the background, and the predilection of DR650SEX to tag a certain river, the Harney Road bridge is certainly the one.

He's also taging around the border. He just might be a Peckerhead.

Not the same bridge, too many details differ....



- One bridge wider than other
- One bridge has an inner Aarmco strip
- Layout all wrong
- Open is open grate other is not open grate
- One is longer than the other

etc...

Even if the photos are shot from opposite ends they don't appear to be a match. Guessing the Tagged bridge is not old... so its not easily found on county documents and Old Bridge websites....

Pennsylvania Peckerheads, Delawhere Douche Bags, So Md InBreds, Bald Eagle Bastards, and over in VA we have Cat Herders, and BullWinkle Death Riders.

What can I say.

The extraordinarily vague clues are a bummer for me.

Well good thing that road isn't all that long...

BTW, if this is correct, it's creepy how the same white car is in the nearly the exact location in the satellite and tag photo!

Uh...yeah, right. Sorry about that. I thought I found it yesterday on my phone and didn't really dive into the details like I should have. (on a phone screen, they're an exact match )
