The Original State Road System, as Shown in 1932

When I was writing yesterday’s blog entry, I had mentioned the fact there were two Official maps issued in 1932. The September 1932 map included something on the front that I had never seen before. It was a small map in the lower right hand corner (given the shape of the state of Indiana, this makes sense that this corner has always been used for the legend and such) that shows “pavement on original system.” Today, the whole purpose of this entry is to show that small map. It gives an idea of who much the state highway system had expanded since 1920. It didn’t include any state road numbers.

A glance at that map gives an idea of what “important” roads were not included in the original state highway system. For instance, not included in the Indianapolis area: the Crawfordsville Road (SR 34/US 136); the Michigan Road north (SR 29/US 421); and the Pendleton Pike (SR 67 and US 36). They were important roads prior to the state highway system…and became major routes after they were added.

Keep in mind that all state roads technically ended at city limits. The Indiana State Highway Commission, when created, was not authorized to route state highways along city streets. It was up to the city to decide those routes. The state would post “trailblazers” pointing the city picked best route to get back to the official state road on the other side of the town.
