^Looking east from Exit 22, the exit to US Route 20 in Portage, May 2023.
Interstate 94 in the vicinity of Indiana is just trying to find its way from Wisconsin to Michigan by detouring around the southern end of Lake Michigan. This places forty-five miles of Interstate 94's length in northwestern Indiana, near Lake Michigan's southern shores. Interstate 94 crosses from Illinois into Indiana concurrent with Interstate 80; then, it drops Interstate 80 onto Interstate 90 and the Indiana Toll Road before continuing easterly and northeasterly into the southwest corner of Michigan. No part of Interstate 94 is tolled in the state of Indiana (that's Interstate 90 you're thinking about).
Exits and mile markers are numbered in increasing order from west to east, as is customary for east-west highways in the United States. The western 21 miles of Interstate 94 are concurrent with Interstate 80.
Interstate 94 enters Indiana from Illinois where Hammond, Indiana meets Lansing, Illinois, and it does so concurrently with Interstate 80 and US Route 6:
