No part of SR 8 in Indiana is included as a part of the National Highway System (NHS). The NHS is a network of highways that are identified as being most important for the economy, mobility and defense of the nation.
The western terminus of the western segment is at U.S. Route 231(US 231) and SR 2 in Hebron. The highway goes due east leaving Hebron and heading toward Knox. It passes through rural farmland, having a four-way stop at SR 49 in Kouts. The route enters La Crosse having a four-way stop at US 421. North of Knox it begins a concurrency with US 35; this ends in downtown Knox with SR 8 heading due east. The road leaves Knox passing through the east side of town. The eastern terminus of the western segment is at SR 17.
The western terminus of the eastern segment begins at SR 9. The road heads east from Albion toward SR 3. On the way to SR 3 the highway passes through rural farmland. The road begins a concurrency with SR 3 at a traffice light north of Avilla; this ends at an intersection with SR 3 on the east side of Avilla. The road then goes due east towards Auburn. It has a four-way stop at SR 327 north of Garrett. The route enters Auburn on the west side of town and has an interchange with Interstate 69(I-69). The road now passes through commercial areas before entering downtown Auburn where it has an intersection with Old SR 427. The roadway now leaves Auburn, returning to rural farmland. The highway has a short concurrency with SR 1. The route turns southeast towards Hicksville, OH. SR 8 ends at the Ohio state line; this is the western terminus of Ohio State Route 18.
In the early 1940s, the road's western terminus was at the Illinois state line, becoming Exchange Street. It was truncated eastward to US 41 in St. John in the 1970s. From St. John to Hebron, it was concurrent to US 231. SR 8 was later truncated to its junction with US 231 in Hebron, eliminating the concurrency.
In the 1950s, SR 8 started in Lake Wawasee at State Road 13 Alternate and continued east to the Ohio state line. That later formed another discontinuous section of SR 8, until that section was deleted in the 1970s.
