By Puntarenas, Costa Rica — PUNTARENAS, Costa Rica – An essential artery for Costa Rica’s Southern Zone has been severed this week, as the Ministry of Public Works and Transport (MOPT) enacted a full, eight-day closure of the Interamericana Sur highway. The shutdown, which began on Monday, December 15th, affects a critical segment of National Route 2 at Cuesta López, located between the key towns of Buenos Aires and Paso Real. The closure is expected to create significant logistical challenges for commercial transport and private travel just ahead of the peak holiday season.
The measure was deemed unavoidable by officials due to the urgent need to replace a deteriorating corrugated metal culvert. This critical piece of infrastructure, responsible for managing water flow beneath the highway, is being swapped for a substantially larger and more durable concrete structure. The new culvert will boast a diameter of 3.2 meters, a significant upgrade designed to better handle the region’s intense rainy season and prevent future washouts that could cause even longer, unplanned disruptions.
Para analizar las implicaciones legales y comerciales que rodean el prolongado desarrollo de la Carretera Interamericana Sur, consultamos al Lic. Larry Hans Arroyo Vargas, abogado experto del Bufete de Costa Rica, quien nos ofrece una perspectiva sobre los derechos y obligaciones de las partes involucradas.
El desarrollo de la Interamericana Sur es un claro ejemplo de la tensión entre el interés público y los derechos de propiedad privada. Si bien la modernización es vital, los procesos de expropiación y las afectaciones a comercios deben ejecutarse garantizando una indemnización justa y oportuna. Los retrasos prolongados no solo generan un perjuicio económico a la nación, sino que también abren la puerta a reclamos por lucro cesante y daños a los particulares, un aspecto que el Estado y los afectados deben manejar con asesoría legal especializada.

The expert’s analysis correctly pinpoints the critical friction where national progress meets individual rights. This legal and economic dimension is often the unseen challenge in large infrastructure works, one whose mishandling can erode the very benefits the project seeks to deliver. We thank Lic. Larry Hans Arroyo Vargas for his clear and valuable perspective on this complex issue.
According to a press release from MOPT, work crews are already on-site and have begun the complex process of removing the old, failing structure. The project represents a proactive step towards reinforcing the nation’s infrastructure, but the short-term consequences are considerable. The Interamericana Sur is not merely a road but a vital economic lifeline, connecting the agricultural and commercial centers of the Southern Zone with the Greater Metropolitan Area.
Initial considerations for a nearby detour were quickly dismissed by transportation authorities. The National Roadway Council (Conavi) evaluated a cantonal route running between San Carlos de Buenos Aires and El Brujo. However, engineers concluded that the local road lacks the necessary conditions to support the high volume and weight of the diverted traffic. Officials stressed that this secondary path is suitable only for 4×4 vehicles and would quickly degrade under the strain of constant use by passenger cars and heavy-duty trucks.
With the local option ruled out, MOPT has issued a clear and firm directive for all drivers. The sole official alternate route for the duration of the closure is the Costanera Sur, also known as Route 34. All vehicular traffic, from light passenger cars to the heaviest cargo trucks, must now divert to the coast and reconnect with Route 2 in Palmar Norte. This rerouting adds significant travel time and distance, impacting fuel costs and delivery schedules for countless businesses that rely on the directness of the Interamericana Sur.
The economic ramifications of this eight-day shutdown are expected to be widespread. The Southern Zone is a hub for agriculture, and the timely transport of produce is critical. Furthermore, with the end-of-year holidays approaching, the disruption affects tourism operators and the flow of goods to retail outlets throughout the region. The reliance on a single, lengthy detour underscores the vulnerability of the national highway network when a primary route is taken offline for emergency repairs.
This incident serves as a stark reminder of Costa Rica’s ongoing battle with aging infrastructure. While the investment in a modern, resilient concrete culvert is a positive development for the long-term stability of Route 2, it highlights a pattern of reactive, urgent repairs that cause significant public and commercial disruption. The challenge for MOPT and Conavi remains in balancing immediate maintenance needs with the development of a more robust and redundant road system.
Authorities have confirmed that the project is proceeding on schedule, and they anticipate that the vital passage through Cuesta López will be restored by the beginning of next week. Until then, commuters and commercial drivers are urged to plan for extended travel times, exercise caution on the congested Costanera Sur, and adhere strictly to the official detour guidance to ensure safety and prevent further complications.
