Overview
- Traffic has resumed at the Lehmann stretch after a five-day shutdown, using a provisional setup that now allows cars and trucks to pass.
- A local municipal worker spotted a hidden failure inside the culvert, which triggered technical checks and an immediate full closure of the corridor.
- Provincial authorities directed the concessionaire and financed urgent works on this national roadway to speed the reopening.
- The temporary solution uses high‑density plastic relief pipes, essentially large drain tubes that carry water under the road until prefabricated modules are installed.
- Officials will survey wear on the paved detour routes between Rafaela and Sunchales to seek compensation from the national government for the damage.
