So back in 2009, the portion of the IN 912 freeway between Michigan Avenue and Calumet Avenue was shut down due to safety concerns. About a year later, the portion between Riley Road and Calumet Avenue was reopened, but westbound only. I happened to notice yesterday that IN 912 is signed westbound along Michigan Ave, Dickey Rd and Riley Rd between the two open portions of freeway.
So what currently exists is a route that is continuous westbound but discontinuous eastbound. What currently shows in travel mapping is two discontinuous segments with the western segment ending at Riley Road, meaning that part of the westbound only section is in the database but not all of the westbound only section. It seems that for consistency, either the route should be made continuous in the database to reflect the continuous westbound route or the western section should be truncated at Calumet Avenue to reflect only the sections that can be traveled in both directions.
