Historic road infrastructure on Old State Road 37 and the Dixie Highway in Morgan County, Indiana

Let’s return to my 2007 road trip along Old State Road 37 and the Dixie Highway between Indianapolis and Bloomington.

This is the segment of old road I spied from current State Road 37 that led me to make this road trip. It turned out to contain two historic pieces of road infrastructure.

The road is signed as Hacker Creek Road at its north end. Its abandoned north tip was visible from current State Road 37. This is the abandoned segment of road I saw while driving home from Bloomington a few weeks before I made this trip, and which sparked my interest in this road. The bridge over Hacker Creek was removed, orphaning this segment. This northbound photo is taken from south of the creek.

Stepping back a bit, still facing northbound, Hacker Creek Road ends before this abandoned alignment with a guardrail and a faded Stop sign. One house is on this stretch of road north of Liberty Church Road, and its driveway is at the end of the road at the right.

Facing southbound from that spot, the narrow road is concrete as far as the eye can see, and it lacks the 2-foot extensions on either side that were common north of Martinsville. What this road also lacks is expansion joints. That’s what makes this road segment distinctive. My research and experience says that Indiana laid its first concrete highways in the early 1920s but didn’t start adding expansion joints until after about 1925. When this road was built, it was a continuous concrete ribbon. With Indiana’s freeze/thaw cycles, the concrete cracked into this pattern.

Sadly, this stretch of concrete is no more. When I-69 was completed here, an exit was built at Liberty Church Road. This map segment shows what happened to that strip of continuous concrete — it was replaced by an offramp. And sadly, south of Liberty Church Road this road was paved over with asphalt long ago.

I wish they could have saved this strip of concrete, as very little continuous concrete highway remains in Indiana. I know of only one other segment, on US 40 in Putnam County, Indiana. I show a photo of it deep in this post.

There is consolation, however. A 1935 concrete-arch bridge on this alignment was bypassed, and the old bridge left in place. The bridge was closed in 2013 because it failed inspection.

But because the bridge was judged as Select on the state bridge inventory, it’s eligible for the National Register of Historic Places and as such can’t be destroyed without a lot of pesky paperwork and approvals. So a new bridge was built, the road realigned to it, and the old bridge and road left in place. In 2007, however, I drove right over it.

After crossing Liberty Church Road, the road is covered with asphalt (and seemed marginally wider) as it gently curves back toward current SR 37.

Next: a beautiful, long old alignment that winds all the way to Bloomington.

    Hi. Ive found 10 or 11 such segments of the old concrete in SC along US 25 where the road was straightened over the years. Several near the Water Resevoir, 3 near Moonville, SC, an abandoned bridge with evidence of at least 1 older and 1 newer, extended concrete road and deep cut of the old drovers road near Edgefield, and fantastic abandoned bridges at Old Hamburg in North Augusta. Only found 1 in NC on the property of a concrete company.

  2. There are still a few pieces of concrete road remaining in Australia that were built during WWII by US Army engineers…..thirty years ago when I lived there there were many miles of it still in use, with every expansion joint making a regular bump and noise as you passed over…
