It was very late to the party: the last segment of the old Michigan Road to be added to Indiana’s modern state highway system.

The state of Indiana built the Michigan Road during the 1830s to connect Madison on the Ohio River to Michigan City on Lake Michigan via the new state capital in Indianapolis.

Indiana built other roads at about the same time, but none like the Michigan Road. Its right-of-way was enormous at 100 feet wide; the road itself used the central third. Even though the road was barely a dirt path at first, it was arguably the grandest road in Indiana. It was a major commerce route that opened deeply wooded northern Indiana to settlers.

The railroad’s rise in the late 1800s led the Michigan Road and all other major roads into disuse and disrepair. But around the turn of the 20th century, the bicycle and the automobile made good roads a priority. Indiana responded in 1917 with its State Highway Commission, which laid a fledgling network of highways over existing major routes and began to improve them, in turn from dirt to gravel to brick or concrete, and eventually to asphalt.

The State Highway Commission numbered just five State Roads in its first year. You might be surprised to learn that the Michigan Road was not among them.

Not in its entirety, at least. State Roads were laid out along portions of the Michigan Road in northern Indiana: from about Rolling Prairie east to South Bend, and then from South Bend south to Rochester.

The east-west segment was part of State Road 2, which followed the 1913 Lincoln Highway, a coast-to-coast auto trail established through the work of entrepreneur Carl Fisher. The north-south section was part of State Road 1, which continued south from Rochester along a new road that passed through Peru and Kokomo on its way to Indianpolis and, ultimately, the Ohio River across from Louisville.

Naturally, all major Indiana cities wanted a good, direct road leading to the state capital, and towns in between wanted to be on those roads. A road would lead from South Bend to Indianapolis. Logansport wanted to be on that route. You have to wonder why the state chose State Road 1 through Peru and Kokomo over the Michigan Road through Logansport. The Michigan Road’s generous right-of-way would certainly ease future improvements. Perhaps the state wanted to provide good-road access to two towns rather than just one. Perhaps Peru and Kokomo had a more effective lobby.

Officials in Logansport went down fighting, agitating for the state to hard-surface the Michigan Road rather than State Road 1 south from Plymouth, as the inset 1919 newspaper article reports. They even claimed — incorrectly — that the Michigan Road was a little shorter.

Alas, State Road 1 was paved.

Indiana expanded its State Road system to more than 50 roads by 1926, adding most of the Michigan Road in the process. The portion from Madison to Indianapolis became State Road 6. The portion from Indianapolis to Logansport became State Road 15.

(By the way, State Road 15 continued northwest from Logansport through Winamac and La Porte to Michigan City, fulfilling the Michigan Road’s mission in much more direct fashion. The indirect route through South Bend had been a compromise — one South Bend certainly enjoyed — to avoid the Kankakee Marsh in northwest Indiana. In the 1830s, no road could be built there. A series of ditches built in the late 1800s through about 1917 drained the marsh, and then by 1922 the river itself was dredged. The direct route finally could be, and was, built. It is US 35 today.)

But the portion of the Michigan Road from Logansport to Rochester remained off the grid.

The U.S. route system we know today was established in 1927. Several State Roads became U.S. highways. Indiana renumbered its State Roads to eliminate numbers the same as the new U.S. routes and to tame what had become a messy numbering scheme. The Michigan Road from Madison to Logansport became State Road 29 (except for a rural segment south of Napoleon in Ripley County, which the highway bypassed to loop in nearby Osgood and Versailles). Old State Road 1, including the Michigan Road from South Bend to Rochester, became US 31. The Michigan Road from South Bend to Michigan City became part of US 20.

Also in 1927, the State Highway Commission decided to build a State Road from Lafayette to Warsaw. To be named State Road 25, it would pass through Logansport and Rochester. At last, this segment of the Michigan Road would join the state highway system! It was added first, in 1928; the rest of State Road 25 was added in stages over the next few years. The state highway map segments above tell the story. In 1923, the Michigan Road didn’t appear between Rochester and Logansport. In 1927 a dotted line appeared to show that the road was approved to be added to the system. In 1928, the thick black line shows that the road was not only added, but hard surfaced, except for a small portion near Fulton. The broken line there and elsewhere on the map indicates a gravel road.

Logansport got its wish nine years too late, as by that time US 31 had become the dominant route to Indianapolis. Not that it mattered much in the long run — US 31 might have boosted Kokomo’s and Peru’s prosperity for a time, but US 31 was rerouted around both towns in the 1970s and traffic through these towns slowed to a trickle. All three towns experienced serious decline toward the end of the 20th century, for reasons bigger than rerouted highways. None is noticeably better off than the others today.
