Only one lane will be available to use on the General Cañas autopista over the Río Virilla for at least a day.
The Ministerio de Obras Públicas y Transportes made the announcement Thursday that beginning this Sunday at 6 a.m. until the following Monday morning at 4 a.m., all passage on the lane currently in service will be shut down.
Officials said that a few seismic blocks along with cables needs to be placed on the road to absorb the impact of the traffic movement on the bridge. The cables absorb some of the tension to relieve the structure of the platina, as the bridge is commonly referred to.
In total, six of these blocks will be placed deep underground to create a concrete structure to take the hits of the construction work and vehicles using the bridge. The other lane going towards Alajuela will remain open but only for that direction, officials said.
The public works ministry does not anticipate too many problems with this closing as it is on a Sunday when traffic is normally light. The ministry suggested that users have the option of the two lanes available at a bridge further east.
This one, between the Pozuelo cookie factory in La Uruca and the Jardines del Recuerdo, has been undergoing a four-lane extension and the installation of sidewalks, pedestrian railing and a central curb separating traffic. According to officials, this bridge is expected to be completed by March 7.
The public works ministry closed the eastbound bridge lanes of the platina for six weeks for construction back in January. The normally four-lane bridge has been restricted to two lanes for either direction.
