Original SR 31 and the Pike’s Peak Ocean-To-Ocean Highway

Just a short post to show how state roads have changed.

I have covered Auto Trails and the original state road numbers several times over the past nearly two years. I had done a post about the rerouting of the Pike’s Peak Ocean-To-Ocean Highway through Indiana. But the original route, as covered by fellow blogger (and ITH Facebook Group co-admin) Jim Grey, traveled across the western part of the state using the US 36 corridor. (The latest is “US 36 and the Pikes Peak Ocean-to-Ocean Highway in Danville, Indiana,” among others) I’d like to say it followed the current US 36, but it’s been moved several times over the years.

As I had mentioned in other posts along the way, many of the roads that were added originally to the state highway system were part of the Auto Trails systems that crossed the United States. When the Pike’s Peak road was taken into the state system, it was given the designation “State Road 31.” Well, sort of.

OSR 31 started in the west at OSR 10, across the Wabash River west of Montezuma. From there, it went through Montezuma, Rockville, and Bainbridge to Danville. From Danville, the PPOO rumbled across Hendricks and Marion Counties along what is now Rockville Road (and Rockville Avenue – because Rockville Road didn’t connect to Washington Street directly until later). The original SR 31, however, connected to the National Road (then Original State Road 3) at a completely different location.

Strangely, the route of the original SR 31 is now not part of the state highway system. Current SR 39 leaves Danville via Cross Street south towards Martinsville. Original State Road 31 turned south from Main Street on Jefferson Street. Jefferson Street turns into Blake Street, then Cartersburg Road. The state road connected to OSR 3 southeast of Cartersburg.

The drive from Danville to Cartersburg is quite a nice one.

With the Great Renumbering in October 1926, original state road 31 became US 36. Again, sort of. The section from Danville to Cartersburg was removed from the highway system at that time. US 36 continued on into Marion County, as shown in the article “Road Trip 1926: US 36.” Just like the original eastern end of OSR 31, the original eastern end of US 36 is now gone, ending at a parking lot.

I also covered a reroute that was put in place along US 36, after the Great Renumbering, at Bainbridge.

  1. This shows what I get for assuming! I assumed OSR 31 would have followed the Rockville Road all the way east.

    The Cartersburg Road alignment is a real puzzler to me. Why that instead of the Rockville Road?!?

    Anyway: I have a few facts to correct in some of my posts.
