El puente La Amistad, ubicado sobre el rÃo Tempisque, ha estado en proceso de remodelación y se espera su pronta reapertura. El levantamiento del puente ha mostrado un progreso significativo, lo que ha llevado a que las autoridades establezcan una fecha objetiva para su apertura.
Durante las obras de remodelación, se han realizado trabajos de sustitución de los apoyos dañados. Estos elementos estructurales son fundamentales ya que transmiten las cargas de las vigas a las pilas y a los batones, y a su vez, a las cimentaciones del puente. Para realizar esta tarea, se están utilizando gatas especiales que permiten elevar el puente y sustituir los apoyos dañados de manera segura.
La sustitución de los apoyos en el bastión 1 ya se ha completado, y esto se logró levantando el puente dos centÃmetros con la ayuda de gatas especiales. Una vez elevado, fue posible demoler los antiguos apoyos y colocar los nuevos.
Además de la sustitución de los apoyos, se están realizando reparaciones en la torre del puente, que tiene una altura de 80 metros, y en la subestructura. Hasta el momento, se han colocado 30 toneladas de acero para garantizar la estabilidad de la estructura. La inversión total en la rehabilitación del puente La Amistad asciende a $2.6 millones e incluye la sustitución de la superficie de ruedo, asà como la instalación de nueva iluminación y señalización vial.
La rehabilitación del puente se lleva a cabo simultáneamente desde cuatro frentes de trabajo diferentes. El primero de ellos es el bastión 1, ubicado en el sector de Limonal. También se están interviniendo las pilas P4 y P8, asà como la torre atirantada que soporta los cables de la estructura. Estos trabajos son meticulosos y requieren el uso de equipo especializado, como el acetileno y herramientas manuales, debido a los espacios estrechos donde se encuentran los bastiones.
A mediados de junio está programado el inicio de la fase de asfaltado y estructura de pavimentos, con una inversión de $2.6 millones. Esta nueva capa de asfalto y las mejoras en la estructura garantizarán una vÃa de alta calidad y segura para los usuarios del puente.
El Ministerio de Obras Públicas y Transportes ha confirmado que la fecha de apertura sigue siendo el 25 de julio. A pesar de que no se ven una gran cantidad de trabajadores en la construcción, esto se debe a que gran parte de las labores de rehabilitación se están llevando a cabo debajo del puente. Esta intervención no solo garantizará la estabilidad y seguridad del puente La Amistad, sino que también prolongará su vida útil, brindando alivio a los residentes y visitantes de Guanacaste que dependen de esta infraestructura crÃtica.
Inversiones y mejoras adicionales en el puente
La inversión económica realizada en la rehabilitación del puente La Amistad ha sido significativa. Además de los costos asociados con las obras de sustitución de los apoyos y las reparaciones en la torre y subestructura, se han destinado recursos para otras mejoras y cambios en la estructura. La iluminación del puente es uno de los aspectos clave para garantizar la seguridad vial, especialmente durante la noche. Por esta razón, se ha instalado nueva iluminación para mejorar la visibilidad de los conductores.
En cuanto a los cables de la estructura, se ha determinado que están en buen estado y no es necesaria su sustitución. Esto ha permitido ahorrar costes y agilizar las obras de intervención. Sin embargo, se han identificado otros daños que no eran visibles a simple vista, como cambios en las juntas de expansión y refuerzos en los apoyos. Estos problemas adicionales se están abordando para garantizar la seguridad y la durabilidad del puente.
Durante los cuatro meses de gestión de reservas que generó el cierre del puente, las autoridades del Ministerio de Obras Públicas y Transportes han implementado diversas medidas para mitigar los efectos negativos. Aunque algunos sectores, como el turismo hotelero, han reportado pérdidas económicas millonarias, se ha trabajado arduamente para asegurar la eficiencia y efectividad de los servicios alternativos de transporte mientras el puente permanece cerrado.

Construction and Progress of the La Amistad Bridge
The La Amistad Bridge, located over the Tempisque River, has been undergoing remodeling and is expected to reopen soon. The bridge’s lifting has shown significant progress, prompting authorities to set a target date for its opening. During the remodeling works, damaged supports have been replaced. These structural elements are crucial as they transfer the loads from the beams to the piles and battens, and in turn, to the bridge’s foundations. Special jacks are being used to lift the bridge and safely replace the damaged supports.
The replacement of the supports on Bastion 1 has already been completed by lifting the bridge two centimeters with the help of special jacks. Once elevated, the old supports were demolished and new ones were put in place.
In addition to replacing the supports, repairs are being carried out on the bridge tower, which stands 80 meters tall, and on the substructure. So far, 30 tons of steel have been placed to ensure the structure’s stability. The total investment in the rehabilitation of the La Amistad Bridge amounts to $2.6 million and includes the replacement of the road surface, as well as the installation of new lighting and road signs.
The rehabilitation of the bridge is being carried out simultaneously from four different work fronts. The first of these is Bastion 1, located in the Limonal sector. Piles P4 and P8, as well as the cable-stayed tower that supports the structure’s cables, are also being intervened. These works are meticulous and require the use of specialized equipment, such as acetylene and hand tools, due to the narrow spaces where the bastions are located.
In mid-June, the asphalt paving and pavement structure phase is scheduled to begin, with an investment of $2.6 million. This new asphalt layer and the improvements in the structure will ensure a high-quality and safe road for bridge users.
The Ministry of Public Works and Transportation has confirmed that the opening date remains July 25. Although a large number of workers are not visible on the construction site, this is because much of the rehabilitation work is being carried out beneath the bridge. This intervention will not only ensure the stability and safety of the La Amistad Bridge but also extend its lifespan, providing relief to residents and visitors to Guanacaste who rely on this critical infrastructure.
Additional Investments and Improvements in the Bridge
The economic investment made in the rehabilitation of the La Amistad Bridge has been significant. Besides the costs associated with the replacement of supports and repairs to the tower and substructure, resources have been allocated for other improvements and changes to the structure. The bridge’s lighting is a key aspect to ensure road safety, especially at night. For this reason, new lighting has been installed to improve driver visibility.
As for the structure’s cables, it has been determined that they are in good condition and do not require replacement. This has allowed for cost savings and expedited intervention works. However, other damages that were not visible to the naked eye, such as changes in expansion joints and reinforcements in the supports, have been identified. These additional problems are being addressed to ensure the bridge’s safety and durability.
During the four months of reservation management that resulted from the bridge closure, authorities from the Ministry of Public Works and Transportation have implemented various measures to mitigate negative effects. Although some sectors, such as hotel tourism, have reported significant economic losses, efforts have been made to ensure the efficiency and effectiveness of alternative transportation services while the bridge remains closed.
