Malla 431A lies in the northwest of the Province of Santiago del Estero, running from south to north along a stretch of Route 34 from km. 720.42 (which is the old Route 34 intersection at La Banda) to km. 856.74 in Garmendia, both in the Province of Santiago del Estero. Work involves repaving the existing road surface, repairing the structure with superficial patches, as well as performing deeper repairs, fissure sealing and recycling.

Subsequently work will be carried out to lay the hot asphalt reinforcement layer and rebuild the verges. This will be complemented with other tasks such as installing vertical signage, reinforcing the berms and bridge balustrades, installing galvanized metal defense rails, and repairing ditches and drainage, among others.

Routine maintenance work has been planned in order to keep the road, shoulders and slopes making up the section in good working condition.
