On August 21, 1922 SH 8 was rerouted from Buna to Beaumont and into Port Arthur via present day US 96.

[6] While the entirety of the route maintained its number, on September 26, 1939 the co-designations were dropped (with US 96 replacing part of US 59), leaving only the Arkansas-Corley segment to the old highway.

On October 13, 1947 a small segment was reassigned back to SH 8 from US 59 from Corley to Linden when US 59 was rerouted further east.

SH 8 was rerouted around the western side of Linden on June 22, 1964, with the old route becoming FM 125 and Spur 400.

The highway briefly turns west with US Route 67 when they intersect in Maud.

The route then turns back north, running along the western edge of the Red River Army Depot.
