Costa Rica’s Route 1 Reopens After Massive Landslide

Authorities reopened a section of Route 1 along the Inter-American Highway near the canton of Cambronero in Alajuela Province, the Ministry of Public Works and Transportation (MOPT) announced.



The order was issued after MOPT crews installed a portable, prefabricated truss bridge, commonly known as a Bailey bridge, to restore traffic flow.



Officials emphasized that the structure is a temporary measure while permanent repairs are designed and carried out.



They urged drivers to cross the bridge with caution and at low speeds to avoid striking the sides of the newly installed structure.



MOPT Minister Efraím Zeledón-Leiva said the bridge provides a short-term solution to keep traffic moving after the road was closed in early October because of a massive landslide. Experts are conducting geotechnical studies to create a long-term work plan for a permanent fix," he said.





Reconstruction of this stretch of Route 1 is expected to take several months due to the steep slope and sharp curve at the site, which pose significant engineering challenges.



The closure followed an Oct. 4 landslide that wiped out the asphalt surface and left the road impassable. The event destroyed both lanes across roughly 100 meters between the cantons of San Ramón in Alajuela and Esparza in Puntarenas.



The highway had remained closed since then until its reopening this past weekend.



The Route 1 repairs are part of a broader effort to improve infrastructure in Costa Rica’s rural regions. Last week, Route 32, the main highway linking the capital to the Caribbean coast in Limón province, reopened to traffic after authorities had restricted travel to a controlled schedule because of high landslide risk.



MOPT is the government agency responsible for overseeing Costa Rica’s roads, ports, airports, and public transportation systems.
