Overview
- The Municipalidad Provincial del Callao approved and the concessionaire began the partial closure on Sunday, June 14, occupying the south‑north lane of Av. Elmer Faucett between Av. Argentina and Av. 28 de Julio to construct ventilation shaft PV4‑7.
- Traffic has been switched so the north‑south carriageway now carries two‑way traffic while the work zone is in place, creating congestion on a primary access route to Jorge Chávez airport.
- Early on the first morning reporters saw cones placed by concessionaire staff but limited signage and few or no personnel guiding drivers, prompting authorities to warn of delays and organize more on‑site direction.
- Project officials report overall progress of about 55% (stations and shafts ~59%), an investment above USD 1,000 million, and an estimated two‑year horizon to finish the Line 4 ramal, though no date was given for lifting the current detour.
- The work on PV4‑7 is one of several concurrent metro interventions in the area, and passengers and drivers are advised to allow extra travel time as authorities coordinate traffic mitigation and related Line 2 operations continue nearby.
