During its first few years of existence, LA 68 extended about five miles (8.0 km) further south into neighboring East Baton Rouge Parish.

LA 68 heads northeast through a thickly wooded area that is interspersed with light suburban development and straddles the East Baton Rouge Parish line for a short distance.

After the surroundings open out onto a wide field, LA 68 passes the Dixon Correctional Institute and its small adjacent airstrip.

Upon reaching a junction with LA 10, signs direct motorists to nearby points of interest and important facilities in Jackson and the surrounding area.

The highway crosses the former right-of-way of the Gloster Southern Railroad (GLSR) line and reaches its northern terminus at a junction with LA 19 one block from the local post office.

By the end of the decade, the northern and southern extensions of this road connecting to Wilson and Port Hudson, respectively, were taken over by the Louisiana Highway Commission.

With the 1955 renumbering, the state highway department initially categorized all routes into three classes: "A" (primary), "B" (secondary), and "C" (farm-to-market).

[15] In the early 1960s, this road was improved and extended north toward the West Feliciana Parish line, streamlining much of US 61 between Baton Rouge and St.

La DOTD is currently engaged in a program that aims to transfer about 5,000 miles (8,000 km) of state-owned roadways to local governments over the next several years.

[18] Under this plan of "right-sizing" the state highway system, the northern portion of LA 68 between Jackson and Wilson is proposed for deletion as it does not meet a significant interurban travel function.
