Latin American road and bridge projects advance in 2026

In Chile, the viaduct linking the Bicentenario Bridge to Avenida Chacabuco in Concepción is 91 % complete and is scheduled to open by the end of 2026, while the new Santa Fe–Santo Tomé bridge has reached 60 % of its viaduct works and 65 % of road works, with traffic diversions planned for the next month. In the same country, the “Beso del Puente” ceremony in Iquique marked the 90 % completion of the Brazil‑Paraguay bio‑ceanic bridge, though final concrete and paving work continues. Red Movilidad in Santiago began bus‑route detours for the 5 de Abril–Del Ferrocarril under‑pass level project that will serve the future Santiago‑Melipilla line.

In Argentina, Rosario’s municipal authority announced extensive street‑work detours and temporary traffic cuts across several central avenues, while Junín’s mayor Juan Fiorini highlighted progress on the Rivadavia under‑pass, a six‑lane, two‑level tunnel with associated drainage upgrades. In Mexico, multiple municipalities reported road improvements: Córdoba’s traffic police were noted absent from daily streets but present at auto‑show parades; Juárez’s JMAS reported 50 % of the Montebello street repaving completed; and the city of Ciudad Juárez urged motorists to use alternate routes during ongoing works.

Ecuador’s capital Quito will start a 70‑day rehabilitation of Avenida 12 de Octubre, affecting over 39 000 residents with planned detours. In the United States, Pennsylvania’s Department of Transportation launched a real‑time, personalized road‑alert service to help drivers plan summer trips and avoid construction‑related delays.
