With the coming “dog bone” intersection completion at US 20 and SR 2 east of Rolling Prairie, I thought it would be a good idea to cover the multiple copies of both of these routes and the roads that were in place before the state highway system was created.
In the 1830s, the state of Indiana created a road that connected Michigan City (a new town created for the end of the road) to Madison on the Ohio River, via Indianapolis. This new road would be called the Michigan Road. One of the things that is constantly wondered about is why the road went through South Bend instead of directly to Michigan City. The reason for that was a very large swampy area known as the Kankakee River. The road was built to stay on dry land as much as possible, simply because it was easier than building across a swamp.
This caused the road to take a very strange detour to the north of a straight line between South Bend and Michigan City. The original path of that road is marked on the image above as the green line. (The orange spots on any of those lines show where the road can’t be followed because it has been moved over the years.) Later on, a road was added connecting South Bend to LaPorte. As was typical of the time with early “state roads,” it would use the then road that was in place until the new road would branch off to go to its new destination. This created the red line on the map above.
In the 1850s, with the coming of the railroads, a line was built from South Bend to Chicago roughly following the Michigan Road for the eastern portion. As is typical at the time, the railroad company basically built in the straightest, most level, line possible. And, being also typical, it didn’t matter to the railroad what they built through. This caused a very dangerous crossing northeast of Rolling Prairie of the old Michigan Road and the new railroad. The town of Rolling Prairie would be put in place to take advantage of both these routes.
Fast forward to the 20th Century. The dangerous crossing of the (then) New York Central is still in place. Due to this crossing, even the post office planned their routes around it, as shown in the above map.
In the mid-1910s, with the beginning of the Auto Trail era, it was decided that the coming Lincoln Highway (original route) would traverse this area. The Lincoln entered Indiana on the west at Dyer, exiting on the east southeast of Fort Wayne. A close look at a map shows that there can be a (relatively) straight line between the two points. And, looking even closer, such a line exists as US 30. But it was decided that the road would be routed through Valparaiso, LaPorte, South Bend, Elkhart and Goshen, among other places. This brought the road along the old state road connecting LaPorte and South Bend, passing to the east of the railroad at Rolling Prairie.
With the creation of the original Indiana State Highway Commission in 1917, it was decided that the new “State Road 2” would follow this original Lincoln Highway route. Again, that would be the red line on the Google Map at the top of the page, then the green line leaving the image at the top right. In 1923, the old Michigan Road, completely, from South Bend to Michigan City, through Rolling Prairie, was changed to SR 25, with the Lincoln Highway’s original route becoming SR 42. (The SR 2 designation was moved to what would become the new route of the Lincoln Highway…aka what became US 30 in 1926.)
Things would change (again) in October 1924 (Source: South Bend Tribune, 03 October 1924), when it was announced that “the Indiana State Highway Commission has determined to relocate state road No. 25 on Division street extended and that maintenance has been withdrawn from state road No. 25 between South Bend and Rolling Prairie through New Carlisle and Bootjack and on state road No. 42 between New Carlisle and a point where Division street extended will connect with state road No. 42.” This was a fancy way of saying that the Lincoln Highway and Michigan Road was being from east of Rolling Prairie to South Bend was being returned to county responsibility. This is shown as the blue straight line from the east (current SR 2) that turns northwest at the original Lincoln Highway, connecting to Rolling Prairie’s Michigan Street (historic Michigan Road). According to the same article, this would shorten the distance between South Bend and either Rolling Prairie or LaPorte by 1.5 miles. The other thing at play with this removal from the state highway system is the pending desire to remove a dangerous grade crossing at New Carlisle. With the rerouting of SR 25 at this point, that makes that crossing a St. Joseph County problem, not one of the Indiana State Highway Commission.
It should be noted that the “straighter” SR 25 from South Bend to Michigan City was also determined, in part, by the desire of the Federal Government. That desire was “for the construction of what might be called a military road through this part of the country in as straight a line as possible.” The decision to use Division Street (now called Western Avenue, by the way) out of South Bend was made by an official of the Federal Government looking at the situation. One comment that made no sense is that “the decision was affected partly by a decision to keep as far away from the central business district of the city as possible.” In South Bend, that would be about 1/2 mile or so, really.
With the Great Renumbering of 01 October 1926, the replacement SR 25 would be recommissioned as US 20 through the area, with the old Lincoln Highway branching to the southwest becoming (once again) SR 2. Half a decade later, the original Lincoln Highway from east of Rolling Prairie to South Bend would be returned to the state highway system. In 1932, US 20 was rerouted to the old road. It was at this time that the US 20 and SR 2 routes would change at their intersection. US 20 would be moved again, from Rolling Prairie to the junction of SR 2, to the route shown on the map at the top as the yellow line, in 1940 or 1941. The old (blue line) route of US 20 through Rolling Prairie would become SR 220 in 1945. It would be that way until 1953.
The final modification in this area would be the creation of the current intersection of US 20 and SR 2 in 1963. The map to the left is from the 1963-1964 ISHC official map. The following official map, of 1964, shows the completed, new, intersection of the two routes.
Let me say, personally, I have never understood why these routes were numbered the way they were. To me, it would have made far more sense to leave US 20 where it was, and make the old route SR 2. But that is not what happened. And now, with the construction of a “dog bone” interchange at that location, the road numbering makes even less sense.
