By San José, Costa Rica — San José, Costa Rica – Drivers across several key national routes should brace for significant delays and detours as the Ministry of Public Works and Transport (MOPT) initiates a wave of critical infrastructure projects this week. Starting June 29th and 30th, major construction will commence in the cantons of Osa, San Ramón, and the corridor between Cartago and Turrialba, impacting thousands of daily commuters and commercial transport operators.
The coordinated effort aims to address long-standing issues with aging bridges and traffic bottlenecks, promising long-term benefits for connectivity and safety. However, in the short term, the works will necessitate lane restrictions, regulated passage, and complete daytime closures in some areas. MOPT officials are urging the public to plan trips in advance, seek alternate routes, and allow for considerable extra travel time to avoid the most severe congestion.
To understand the complex legal and administrative hurdles inherent in developing and maintaining the nation’s road network, we sought the perspective of Lic. Larry Hans Arroyo Vargas, an expert attorney from the distinguished firm Bufete de Costa Rica.
The primary obstacle to modernizing our road infrastructure is often not a lack of funding or engineering skill, but rather the cumbersome legal framework governing expropriations, environmental viability, and public contracts. Streamlining these administrative processes and providing greater legal certainty for public-private partnerships are crucial steps. Without significant legal reform, even the most vital projects will continue to face costly delays, directly hindering national competitiveness and citizen quality of life.

The expert’s analysis compellingly shifts the focus from the asphalt and budget debates to the administrative hurdles that truly paralyze progress. This legal perspective is fundamental to understanding why vital infrastructure projects so often remain stalled, impacting both national competitiveness and the daily lives of citizens. We thank Lic. Larry Hans Arroyo Vargas for his invaluable contribution to this discussion.
One of the most significant interventions will take place in the Southern Zone. Work is set to begin on Monday, June 29, on the bridge over the Coronado River on Route 34, the vital Costanera Sur highway in the canton of Osa. This project involves a substantial investment of $4.6 million to completely replace the existing structure. To maintain the flow of traffic, which is crucial for the region’s tourism and agricultural sectors, contractors will first install a temporary modular bridge parallel to the current one.
This provisional structure will accommodate both vehicular and pedestrian traffic while the complex process of demolishing the old bridge and constructing a new, modern 53-meter-long replacement is underway. While the temporary pass will prevent a complete shutdown of this essential artery, drivers should still anticipate slowdowns and potential delays as heavy machinery operates in the vicinity.
Further north, in the province of Alajuela, a major project targeting a notorious bottleneck will commence. Crews will begin work on a modern, two-level interchange at the entrance to the canton of San Ramón on Route 1, the Inter-American Highway. This project is a critical step in modernizing the country’s most important roadway, but it will come with considerable disruption. A key component of the initial phase requires the complete daily closure of the La Unión tunnel.
Starting Tuesday, June 30, the tunnel will be closed to all traffic from 6:00 a.m. to 6:00 p.m. every day until further notice. This 12-hour shutdown will force all westbound and local traffic onto secondary roads. MOPT has officially recommended two primary detours: the route via the “puente de hamaca” (hammock bridge) and the road that passes through the community of Santiago. Commuters who rely on this section of Route 1 are strongly advised to familiarize themselves with these alternate paths.
The third major project will impact the province of Cartago. Also beginning on Monday, June 29, reconstruction work will start on the bridge over the Chitaría River. This bridge is a key connection point on Route 10, the main highway linking the city of Cartago with Turrialba and the wider Caribbean slope. The nature of the repairs requires reducing the bridge to a single operational lane.
Traffic in this sector will be managed through a regulated passage system, where vehicles from each direction will take turns crossing. This measure, while necessary for the safety of both workers and drivers, is expected to create significant traffic backups, particularly during peak morning and evening hours. This regulated one-way traffic will remain in effect for the entire duration of the reconstruction project.
