Costa Rica. The new overpass where Constructora MECO participates, located between Hatillo and Zapote progresses smoothly despite the challenges it has faced due to processes of expropriation by the state and the effects caused by rains that marked the beginning of 2015.
The work has an advance of 31% which highlights the construction of ramps and marginal bridge substructure walls and floor sewn pile wall, works that have been successfully implemented without interrupting the traffic of about 90,000 vehicles that travel daily on this route.
Given the heavy traffic flow, Constructora MECO adopted additional measures, to those implemented in other projects as precautionary, to protect workers on the project and the thousands of drivers who daily travel through the site.
These actions include placing of New Jersey- type barriers made of higher strength concrete to prevent vehicles from falling in any mishaps, the use of speeders in both directions and a permanent light-signaling.
In March 2015, the bridges, the beam head and bastions of the overpass were partially concluded. The second stage of the project is to start in April, where assembly of steel beams and building the pile wall to the viaduct will be finished. This stage will take approximately three months.
It is estimated the work will be delivered on January 10th, 2016.
