OSR 2/US 30 at Plymouth

When the Indiana state highway system was being expanded in 1920, one of the additions was what was, at the time, the Yellowstone Trail from Valparaiso to Fort Wayne. This Auto Trail snaked its way across the Hoosier landscape, nowhere near anything resembling a straight line. It was added to the system as SR 44, connecting at both ends with SR 2, or the Lincoln Highway. The original route had the road entering Plymouth from the west and the south. The Yellowstone Trail, and the state highway that came after, didn’t go straight through the Marshall County seat.

That was about to change. But first, a number change was in order. In 1923, the Indiana State Highway Commission started changing state road numbers. One of those that would change would be the Lincoln Highway…and SR 44. The SR 2 designation was moved from the Lincoln Highway to the Yellowstone Trail. This “straightened” the road between Valparaiso and Fort Wayne…SR 2 no longer ran through Goshen, Elkhart and South Bend. But the road still was a winding mess between Warsaw and Plymouth.

With the concept of federal aid funding sitting in the background, the state decided it wanted to fix the twists and turns of the original Yellowstone path. The first reference to this project that I found was in August 1925…but it wasn’t good news. The project was “abandoned” due to a $5 million shortfall in federal funding. Or, more to the point, a belief that the state was going to get $5 million from the federal government that hadn’t quite made it to Indianapolis. Two projects were actually put on hold with that shortfall…both of which were in northern Indiana. One was the SR 2 project. The other was the Dunes Highway along Lake Michigan.

The article that made it to most Indiana newspapers in mid-August 1925 lamented that the northern part of the state would be paying for the delays in funding. It also mentioned that most of the road was a hard surface (paved) road from Columbia City eastward to Fort Wayne. The section shown both in the map above and the one below show that the road is “gravel or stone (not treated)” between Warsaw and at least Hamlet…through Plymouth.

The new maps issued in late September and early October 1926, with the Great Renumbering, show the construction is at least still planned, as the circles on the map are listed as “proposed relocations.” The new US 30, which was SR 2, would be given a straighter route from Warsaw to Plymouth. And it would actually enter Plymouth from the east, not follow SR 1/US 31 south out of town like it did originally.

In relative terms, it wouldn’t take long for this new road to be completed. The South Bend Tribune of 20 November 1927 reported that construction was almost complete in a plan to avoid crossing the Pennsylvania Railroad for 75 miles, something the old Yellowstone Trail/SR 2/US 30 did quite a bit. As of the writing of the article, 16 miles to the west of Plymouth were completed. This connected US 30 to SR 29 (now US 35), a “recently improved asphaltic macadam” road.

As a side note, the section west from SR 29 to Hanna was also part of the project, but was in a serious holding pattern. The road was “a stretch of about 10 miles in which no concrete has been laid and cannot be laid this year because of two sink holes in the vicinity of the Kankakee river which have materially resisted grading and filling by the contractors.” That section of US 30 is still in use today…albeit a bit wider than it was at that time.

East from Plymouth, the road was open, according to the Tribune, to Bourbon, a span of 10 miles. Four bridges being constructed between Aetna Green and Warsaw were all that was standing in the way of opening the road on or about 1 December. The article mentions that the route actually enters Plymouth from the east along Pennsylvania Avenue. This is due to a bridge on what is now called Lincoln Highway over the Yellow River being built. Pennsylvania Avenue connects to Michigan Street (old US 31) just north of the old Pennsylvania Railroad Fort Wayne Line (and, for those that are landmark oriented…right at the Penguin Point restaurant).

And, in case you are wondering, the name Lincoln Highway would be officially applied to this road in 1928, one year after this construction. The places where the name “Yellowstone Trail” still exist as a road name were sections of the original path of that road…parts that weren’t improved as a part of the state highway system.

  1. This article is very helpful as we research and write about the Yellowstone Trail. We have had ongoing questions about the gradual improvement/relocation of the YT in Indiana during the late 1920s. Decisions about the improved road were made by state officials whereas decisions about the route of the YT were made by leaders in the Yellowstone Trail Association which was headquartered, at that time, in Minneapolis, without governmental involvement.

    Basic information and maps of the Trail can be found at http://www.yellowstonetrail.org
    The included maps are penultimate copies. Some changes and corrections will be found in our upcoming book: The Open Road, An Auto Route from Plymouth Rock to Yellowstone National Park and Puget Sound •1912 to 1930

    The Trail is being marked by “friends of the Trail” slowly and in scattered locations. Join the effort!

  2. very intresting article to me. I lived near the yellowstone trail and have traveled many miles of it at differant times. also, my grandfather worked on the yellow river bridge where he operated a crane which tipped and fell into the river during construction. never knew for sure the year this happened. thanks for a great item!

  3. When I read this post, I went searching for additional information about the Yellowstone Trail. A friend recently mentioned that the YT went through Hamlet. I found another article online which includes photos of YT signs. I’ve driven most of what I believe to be the old YT route between Warsaw and Valparaiso. I’ve seen Lincoln Highway signs along that route, but I don’t recall seeing any Yellowstone Trail signs. Is the YT marked in Indiana?

    1. The Yellowstone is not marked in Indiana. I don’t know, personally, of anywhere that it is. Not saying it isn’t, just don’t know of any. Had the Lincoln Highway Association not changed the route to follow US 30, then the whole section from Valparaiso to Fort Wayne would be marked as the Yellowstone.
