Another strange bird of a route, and Indiana is probably happy that it never got the I-294 moniker the state had asked for in 1970. All expressway except for the portion south of I-94; the signage is spotty (better off the road than on), the interchanges almost bizarre and the scenery is an ugly mix of rusting old steel plants, petroleum storage structures and low-rise projects that are as bad as they look. The scenery south of US 12 can almost be considered worth looking at IF you're willing to overlook the random industrial and post-industrial buildings along the route.

Before the expressway portion was built, Indiana 912 originally went up Guthrie Street from Cline Avenue, then jogged over to Dickey Road before going down 129th to US 41. That route would put people through the worst part of Indiana Harbor, the middle of a largely unused steel complex, and past a small, tightly packed settlement called Marketown before sending them through Amoco oilfields and what can best be considered a brownfield (although I have no idea what would have been there beforehand, as it's almost halfway between Robertsville and Hammond, and there's no sign of settlement anywhere nearby).
