“We have reactivated this project with UNOPS, because it is a strategic partner, because we already had experience of the Virilla bridge, which is equal, because we must take advantage of the opportunity to work with the accesses to the bridge that had already been designed and we have the possibility of reviving the economy, generating transparency and creating jobs. This is what the country needs today, to carry out the works”, explained Mauricio Batalla, executive director of CONAVI about the decision to move forward with this project under the previous agreement that existed. already with UNOPS.

In addition, Batalla explained that under this agreement, the estimated cost of the project is maintained in April 2020, even in the context of inflation and rising raw material costs and that the project’s expected duration is reduced by 3 months.

This bridge was built in 1986 and since its commissioning it has suffered damage such as deformations, deterioration of structural elements and accessories, an aspect that has worsened due to the lack of maintenance during its operation. In addition, since its design and construction, the seismic design standards for bridges have been updated, which requires strengthening them to comply with current regulations and thus

Finally, an adequate drainage system will be built to ensure the proper evacuation of water on the platform, the access roads to the piers will be adapted and a pavement structure will be built on the northern access of the bridge, which is connects with the future expansion. . of the National Road n° 32.
