There’s but one old alignment of the National Road in eastern Indiana, and it stretches 4 miles from Dunrieth west through Raysville to the east edge of Knightstown. From there it’s about 33 miles to downtown Indianapolis.
Modern US 40 was built in about 1940, leaving this old route behind. Here’s where it begins on Dunrieth’s west edge. This is an eastbound photo. It’s cut off from US 40; to reach it, you have to turn south in Dunrieth proper and follow the town’s streets to this location.
Turning around from the same spot, here’s the westbound road. Whenever I see an old alignment covered in asphalt I’m intensely curious to know what paving materials lurk beneath. Concrete? Brick?
As the road enters Raysville it runs under this old Pennsylvania Railroad overpass.
On the other side of the overpass, facing eastbound, this little sliver of road breaks off from the old National Road. It’s signed Star Blvd.
As you can see in the map snippet below, it curves up and around much like modern US 40 does. I wondered for a long time whether this was a newer old alignment of the road. Did the state reroute the National Road more or less along its modern alignment between Dunreith and Raysville some number of years before building the modern four lane, divided road?
I asked the wonderful Indiana Transportation History group on Facebook. I got my answer fast: it’s a previous routing of that PRR line. It was actually part of the old Indiana Central Railroad before PRR bought it and built the grade separation and new alignment. They did that in the 1900-1920 timeframe. Star Blvd. is the old PRR rail bed.
There it is, the old PRR bed, currently a narrow road for local traffic. The old National Road and US 40 had but two alignments here: the original and the 1940 US 40 expressway.
