Let’s return to my 2007 road trip along US 36 and the Pikes Peak Ocean-to-Ocean Highway in western Indiana.
West of Rockville the map showed two places where a road diverged from US 36 only to return to it. That’s a sure sign of an original alignment.
This looked to me remarkably like the shape of the road at this spot in the 1915 TIB Guide strip map that I saw at the Federal Highway Administration’s Web site where they were tracking the route of the old Pikes Peak Ocean-to-Ocean Highway.
About 3½ miles past Rockville I came upon where this road split from US 36.
I turned in, and the road immediately turned to gravel. This westbound photo was taken several feet away from US 36, and you could hear the traffic whizzing by. But doesn’t this photo seem to be miles away from anything? Doesn’t it look like it ought to be pin-drop quiet?
I checked my old state maps, which go back to 1936. They aren’t detailed enough to accurately render the shape of US 36 through here, but they do say that US 36 was paved. It’s possible this segment was never US 36, but it was certainly the PP-OO.
After about a quarter mile this road became paved and its name changed from W 25 N to N 350 W. A couple houses appeared. Another quarter mile later, it deposited me back onto US 36. This eastbound photo shows the old road’s ascent to the highway.
Another quarter mile or so down US 36 the next segment began. The map suggests to me that this segment used to flow smoothly from the previous one, and that it came in from the gravel driveway on the left in this photo.
Off the road goes westbound. The presence of utility poles suggests that rural electrification reached here before US 36’s current alignment did.
Soon this old alignment meets Arabia Road. The Phillips covered bridge is a couple hundred feet down this road. It was built by J. A. Britton in 1909.
There wasn’t much along this old PP-OO alignment but soybeans.
Shortly I came upon the 1883 Sim Smith Bridge, a Burr arch truss bridge also built by J. A. Britton. I didn’t think much of the “Warning Flooding Possible” sign as it blocked this, the best angle I found of the bridge.
Here’s a better look at those curved Burr arch trusses.
After crossing the bridge the land deepened into a mild valley overgrown with weeds. US 36 came into view on my right. I could see that the road made an unusual jog to the left up ahead, and when I reached it I felt a mild bump and heard my tires make a different sound, as if I had just changed roads. I pulled right over to have a look. I could see a faint double yellow line on the road.
The road had a shoulder on its north side, and it looked like the road and its shoulder were summarily chopped off beyond a certain point, as this photo shows. The little red, white, and black sign at right says “Danger Flooding Possible.”
The only evidence I found of the road’s former path was a drainage trench. It hugged the road’s shoulder to where the road was cut off, and then it snaked around the ridge.
I drove on, and soon the old road was blocked by these gates. Fortunately, a curve had been built here to connect the road to current US 36.
It looked to me like the road used to go through where these gates are now. This land looks built up like a roadbed.
From this evidence, I conclude that a former US 36 bridge over this creek was built in the flood plain. That became enough of a problem that the state built a new bridge nearby, raising it far above flood levels, and rerouted US 36 onto it. The blue line on this map shows where I think old US 36 used to go.
