Today’s Road Trip, US 27. Indiana, in the beginning, only had three north-south US routes: US 27, US 31 and US 41. Part of this is simply the fact that Indiana is a lot taller than it is wide. The first one, US 27, skirted the eastern edge of the state. Today, US 27 has been decommissioned above Fort Wayne. That was a long time coming, since INDOT and MDOT (the Michigan counterpart) had agreed to move US 27 to multiplex with I-69.
