Once complete, the freeway will run approximately 117 miles (188 km) through Northeast Texas beginning at an interchange with I-69 east of Tenaha and head northward to Carthage, Marshall, Jefferson, and Atlanta to its current northern terminus at I-30.

[6] This action meant that the Texas Department of Transportation (TxDOT) could commence the signing of I-369, as well as the other route segments cited, at their discretion.

[9] Plans call for I-369 to begin at US 59/US 84/Future I-69 in Tenaha, then head north along US 59, serving Carthage, Marshall, Jefferson, and Atlanta before entering Texarkana and merging onto its current routing at the western terminus of Loop 151 and terminating at I-30.

[10] The proposed routing of I-369 in the Marshall area has the Interstate running east of the city and using part of the existing Loop 390 corridor.

[10] Public feedback on the middle section, which will would require 536 acres (217 ha) of new right-of-way and potentially displace 25 residences, four commercial buildings, and two utility locations, was requested in September 2023.
