Overview
- From 4 p.m. to midnight on March 1, the contraflow operates between Santa María del Mar and the Atocongo bridge as part of Plan Verano 2026.
- Two southbound lanes are reversed to create five lanes toward Lima, leaving a single southbound lane that is diverted via the Antigua Panamericana Sur at the Puente Arica.
- The National Police oversee operations with Armed Forces support, with controlled boarding points and a segregated lane for public transport during a marcha blanca before cargo-traffic sanctions.
- EMAPE estimates travel times on the affected stretch could fall from about 90 minutes to roughly 45 minutes, with the scheme scheduled to run again on Sunday, April 5.
- In Arequipa, temporary two‑way traffic is enabled on avenida Juan de la Torre as uphill paving pauses until at least March 2 due to Sedapar, and Lima’s Línea Amarilla tunnel toward downtown has a two‑hour, two‑lane closure at midnight that prohibits wide loads.
