Overview
- Provincial officials opened bids for the Guaymallén tranche, logging seven offers from 14 companies for a work budgeted at ARS 70.5 billion (about USD 50.3 million) financed by the Fondo de Resarcimiento.
- Authorities plan 45–60 days to evaluate proposals before contracting, with works slated to start in the first semester of 2026 and a total execution period set at 30 months with interim openings.
- The upgrade adds a third lane in each direction, elevates the roadway by about six meters to build three underpasses linking key cross streets, and covers lighting, signage, safety barriers, and bridge expansions across 11.6 kilometers.
- Traffic preparations begin February 9 with one‑way flows on the laterals (north: east‑to‑west; south: west‑to‑east) and a parking ban between specified crossings, easing drivers into diversions that will affect roughly 120,000 daily trips and include full closures during the most complex phase, according to local officials.
- A four‑year provincial–municipal agreement lets Guaymallén perform minor maintenance and co‑manage adaptive signal operations with remote monitoring while the province handles complex faults to keep detours moving during construction.
