Ferguson Quarry Bridge


Brush Creek Bridge

View from the south. My camera battery died and I had to take this with my phone. I am waiting to hear back to try and get permission to see this up close.

Maybe try visiting the bridge on a Sunday when nobody is working? I doubt the Quarry runs much traffic over this bridge given most of their traffic would be too heavy for the bridge. Looks like they are running a small black hose or something over it based on the imagery.

Looking at the 1980 topo, it shows a much smaller quarry and Vance Avenue running all the way south across the bridge to the highway. Obviously the county abandoned the road so they may have given up the bridge as well. My guess is the quarry kept the bridge since the creek divides the site.

From the satellite view, the bridge looks to be on a haul road through the divide between an active section of a stone quarry and a section that has already been mined out and re-claimed. This isn't the type of place that unannounced visitors are welcome. So be safe and smart and keep your wits about you,especially if tomorrow is a blasting day.

I can definitely see now it is not. Thanks guys. That shadow had me spoofed. I will try to access it if at all possible tomorrow when I'm out that way.

Take a look at this Bing view and you can see a 5 panel through truss that looks to be an older pinned Pratt. Not a bowstring unfortunately...but still looks like a very nice find!

Looking at it in Bing Bird's Eye, it's definitely NOT a bowstring.

It looks like a Pratt through truss to me.

I just found this on satellite looking around where I will be tomorrow and noticed this. Looks to be a bowstring but I can tell if pony or through. Any thoughts?
