I just subscribed to your thread. It looks like a great start to what could become an awesome thread. I enjoy chasing bridges myself and am fairly close to your area so I'll be watching to see how many of your bridges I can add to my ever-growing bucket list... I have just recently gotten back in the saddle after (30) long years of being lost in a cage so I have a lot of catching up to do.
I had to laugh at jdfog2's comment about the ( "Pirate" looking dudes on chromed out loud and low bikes. ) as I somewhat resemble that remark, with my long hair and riding a chromed out Harley Sportster, although my bike isn't too awfully loud and I would never ride it to a bar.
I'm usually riding two-up with my Ol'lady on the weekends, although I do ride alone sometimes, and we enjoy getting out on the back roads searching for the places that time has almost forgotten about. We'll take the Sporty just about any place it'll go without it " crying " and making too much of a fuss about and I look forward to possibly riding along with you, jdfog2, and any others that enjoy a good ride, in the near future.
I'll leave ya with these two photos of our most recent bridge that we have crossed off our list and hopefully it's one that you were not aware of and can add to your list... It's located on the Hendricks/Putnam county line and it's a fairly nice area with some good riding roads. ( 39°49'50.47" N 86°41'12.02" W )
View looking south:
View looking north:
The road has a bit of washboard gravel to the north and the McCloud Nature Park is located right around the corner just southeast of there. I believe there is also another old restored iron bridge located within the Nature park itself although it was simply way to hot for us to check it out the day we were there.
I look forward to viewing your thread and possibly hooking up some day.
Best of luck in your travels, Ride safe, & Have a great day, Jeff...
Ooops, P.S.> I also have a list, and somewhat of a route layed out, for about (15) bridges, ( Mostly Covered ), located in Putnam County if your interested in seeing them.
