Transport officials are closing the Autopista General Cañas at the Río Virilla bridge again Tuesday, Wednesday and Thursday nights.
The closing will be at 10:30 p.m. and last until 5 a.m. the following day, officials said.
This is yet another effort to repair the recently repaired bridge. The effort this time is to finish repairing the faulty concrete that began breaking up as soon as the highway was open to traffic again earlier this year.
The concrete was spread on a grid of steel bars to form the bridge deck. Officials still have not said exactly why but the concrete began breaking up in the spaces between the steel.
Contractors did work nights for a time ending last March 20.
