Overview
- The Stage II‑B call divides more than 2,500 km into four corridors—Mediterráneo (672 km), Puntano (720 km), Portuario Sur (637 km) and Portuario Norte (528 km)—across Buenos Aires, La Pampa, Santa Fe, Córdoba and San Luis.
- Bidders must file questions until April 27, 2026, and submit offers by May 7 with the opening that same day via the CONTRAT.AR portal; an ad hoc evaluating commission was created and the notice is published on official and international platforms.
- Concessionaires will handle construction, operation, expansion, maintenance and user services and may pursue complementary exploitations, with financing centered on toll collection rather than state subsidies.
- Tender documents detail long‑term contracts of up to 20–30 years, free‑flow or automated tolling, and initial works such as a third lane on the Rosario–Buenos Aires access between the A008 and A012; the Rosario ring road has no planned toll booths, while up to five may be authorized on National Route 33.
- Local and sectoral responses note the omission of the Mendoza segment of Route 7 in this round—provincial officials say it is expected in a subsequent call—and road‑worker representatives warn that roughly two‑thirds of national routes are in regular or poor condition.
