The Autopista General Cañas bridge over the Río Virilla is being closed again Sunday from 6 a.m. to 2 p.m.
This is another step in the two-year-long effort to repair the bridge. Once again the firm Soares Da Costa will be pouring concrete to cover rebar that has been exposed by heavy traffic.
The Ministerio de Obras Públicas y Transportes is quick to point out that the repairs do not involve sections that were just repaired.
The traffic has crumbled the concrete top layer of the
bridge. This is the famous platina bridge, called that because a plate over an expansion joint became loose. The ministry closed the bridge during Christmas in an effort to repair it.
Engineering sources not connected with the ministry have suggested that there is something fundamentally wrong with the span that causes it to vibrate excessively, thus damaging the roadbed.
The highway is the one that connects San José with Alajuela and Juan Santamaría airport.
The Policía de Tránsito will be on duty Sunday to direct motorists to detours.
