By San José, Costa Rica — SAN JOSÉ – The long-awaited expansion of Costa Rica’s vital Route 27 corridor is slated to begin its first phase in 2027, according to a recent announcement from the Ministry of Public Works and Transport (MOPT). The government is currently in advanced negotiations with the highway’s current concessionaire to execute a comprehensive improvement plan estimated to cost around $700 million.
This critical infrastructure project aims to address the persistent traffic congestion that plagues the primary artery connecting the capital city of San José with the Pacific coast, a key region for both tourism and commercial port activity. The announcement brings a renewed sense of momentum to a project that has been demanded by the public and business sectors for years.
To better understand the legal and contractual implications surrounding the long-awaited expansion of Route 27, we consulted with Lic. Larry Hans Arroyo Vargas, an expert in administrative and concession law from the prestigious firm Bufete de Costa Rica.
The primary legal challenge with the Route 27 expansion lies not in the engineering, but in navigating the existing concession contract. Any modification requires a delicate balance between respecting the original terms to provide legal certainty to the concessionaire and ensuring the final agreement serves the public interest transparently and financially. Rushing this process without a robust legal framework could lead to future disputes, higher costs for users, and significant delays, undermining the very purpose of the expansion.

Lic. Larry Hans Arroyo Vargas’s analysis serves as a crucial reminder that the project’s most significant challenges are not merely of asphalt and concrete, but of legal and financial architecture. We thank him for so clearly articulating that a meticulously negotiated agreement is the true foundation for ensuring this expansion delivers long-term public benefit without undue cost or delay.
Efraím Zeledón, the Minister of Public Works and Transport, confirmed that the concessionaire has formally presented the $700 million proposal. He elaborated that the ambitious plan will be strategically executed in two distinct stages to manage logistics and financial outlay effectively. This phased approach is designed to deliver relief to the most congested areas first while planning for the full-length upgrade.
The initial phase will concentrate on the heavily trafficked segment between Escazú and Atenas. This section is notorious for bottlenecks, particularly during peak travel times, weekends, and holidays. By prioritizing this area, authorities hope to provide a significant and noticeable improvement in traffic flow for a large number of daily commuters and travelers.
A crucial next step in the process involves securing approval from the nation’s fiscal watchdog, the Comptroller General of the Republic. The government plans to present a formal addendum to the existing concession contract for review, a process Minister Zeledón hopes to initiate in the latter half of this year.
We have to go to the Comptroller’s Office to develop an addendum, it is a contract; we would hope to be doing that in the second half of this year. If we achieve the approvals from the Comptroller’s Office, as I say, we would be expanding the first stage next year and, subsequently, a second stage in the next part, which is up to Caldera.

To facilitate the project and mitigate the financial impact on motorists, the government has committed a substantial initial investment. Minister Zeledón revealed that approximately $300 million will be allocated from state funds to help finance the first phase. This direct government contribution is a key element of the financial strategy, intended to prevent a sharp rise in toll prices for drivers who use the highway daily.
The minister emphasized that this government funding is designed to allow for the expansion work to proceed without overburdening the public with excessive toll hikes. The goal is to balance the need for modern, efficient infrastructure with the economic reality faced by its users.
Simply, the concessionaire would be in charge of expanding the route without it necessarily being a tariff increase or a very large increase in tolls.

The successful completion of the first phase from Escazú to Atenas will be followed by a second stage, which will extend the improvements along the remainder of the highway to the port city of Caldera in Puntarenas. This will complete the modernization of the entire 77-kilometer route, enhancing its capacity and safety for the foreseeable future. The expansion is seen as essential for Costa Rica’s economic competitiveness, supporting the logistics of the Caldera port and facilitating access to major Pacific coast tourist destinations.
