It opened on a Wednesday afternoon in late May, and within hours, it had swallowed part of one of the most important stretches of asphalt in our country. The sinkhole that appeared at kilometer 56 of Route 27 near Coyolar in Orotina was more than a road problem. It was a sharp reminder of how fragile the infrastructure connecting Costa Rica’s economic heartland to its Pacific coast tourism engine is.
The cause was a collapsed culvert beneath the highway, overwhelmed by the heavy rains that arrived with the early onset of the 2026 rainy season. Water and debris surged through the drainage system beneath the road until the surface above simply gave way, opening a deep crater that cut across both lanes near Las Fruteras. Drivers who arrived at the scene found an impassable gap where a modern toll highway had stood minutes before.
The closure was immediate and total. Route 27, formally known here as the Autopista del Sol, is the primary corridor linking San José and the Central Valley with Caldera, Puntarenas, Jacó, and the broader Central Pacific tourism zone. It is one of the most heavily traveled roads in the country, carrying thousands of vehicles daily, including freight trucks supplying the port of Caldera, tourist shuttles heading to beach destinations, and commuters moving between the Pacific coast and the capital.
Within hours of the closure, long lines formed in both directions, and transportation officials put into place alternate routes through the older and significantly slower Inter-American Highway via Cambronero.
The alternate routes provided some relief but came with their own complications. The Cambronero route is steep, winding, and not suited to all vehicles. Freight movement slowed considerably, adding cost and delay to supply chains that run through Caldera. Tourism operators along the Central Pacific reported immediate disruption as travel times from San José stretched from roughly one hour under normal conditions to three hours or more, depending on traffic.
The Ministry of Public Works and Transport moved quickly, announcing plans to restore a single regulated lane using alternating one-way traffic while crews worked on a more permanent solution. A modular bridge was ordered to span the crater, with expectations that two lanes could be restored by early the following week.
But continued heavy rains in the area complicated the repair timeline, with machinery on site unable to work safely during the heaviest downpours. The concessionaire Globalvía, which operates the highway under a long-term concession agreement, was coordinating the repairs alongside government engineers but offered no firm reopening date as conditions on the ground remained unpredictable.
The wider implications go beyond the inconvenience of a detour as Route 27 represents a significant public and private investment in modern infrastructure, and its vulnerability to highly disruptive infrastructure problems under heavy rainfall raises legitimate questions about the maintenance standards applied to the highway’s drainage systems.
The Ministry placed the entire national road network on alert following the incident, acknowledging that the fifth tropical wave of the season had arrived and that soil saturation across much of the country was creating elevated risk of similar failures elsewhere.
For Costa Rica, where tourism and trade depend heavily on the reliable movement of people and goods between the capital and the coasts, a hole at kilometer 56 is never just a local problem.
