San José - Caldera Highway

The San José-Caldera highway is considered as the project that will position Costa Rica in the group of countries that carry out works through public concession. The construction of the road began on January 9, 2008. The project is made up of three sections:

 

1) San José - Ciudad Colón

Construction on this section began in 2008 and was completed in May 2009. It spans 14 kilometers and involved upgrading the existing four-lane roadway (two lanes in each direction) while expanding it to six lanes between the Circunvalación and Multiplaza interchanges.

Key Features and Improvements:

  • Maximum speed limit: 80 km/h
  • Pavement rehabilitation throughout the entire section
  • Enhancement of existing interchanges
  • Construction of sidewalks, bus bays, pedestrian bridges, and lighting
  • Bridge improvements and structural rehabilitation

2) Ciudad Colón - Orotina

As outlined in the Concession Agreement, this newly constructed 38 km section was inaugurated in January 2010.

Since it was built from scratch, the key construction efforts included earthworks, drainage system installation, retaining walls, grade-separated structures, interchanges, and pavement works.

Some of the communities along this route include San Rafael de Alajuela, La Guácima, Siquiares, Turrúcares, Cebadilla, Concepción de Atenas, Pan de Azúcar, Balsa, Escobal, Dantas, Hacienda Vieja, and Orotina.

Key Features and Works:

  • Maximum speed limit: 80 km/h
  • Fully new roadway construction, with five bridges built by the Public Administration
  • Typical road section: Two lanes (one per direction) with an additional climbing lane in steep areas
  • Construction of interchanges and overpasses
  • Development of marginal roads

3) Orotina-Caldera

The construction of this section began in September 2008 and was completed in May 2009, covering a total of 24 km of the existing roadway, which consists of two lanes—one in each direction.

For pavement laying, advanced machinery was used to recover and repurpose existing materials.

Key Features and Improvements:

  • Maximum speed limit: 80 km/h
  • Flexible pavement rehabilitation: Two lanes (3.65 m each) with 1.80 m shoulders
  • Enhancements to existing interchanges
  • Construction of marginal roads
  • Reinforcement of the bridge over the Jesús María River
  • Construction of bus bays
