Highway officials say they expect to have elevators at three pedestrian bridges in service by December.
The bridges are at Hospital México in La Uruca over the Autopista General Cañas, Tres Ríos de La Unión over the Autopista Florencio del Castillo and Quesada Durán over the Circunvalación.
The bridges went up before a law that provided accommodations for seniors, pregnant women, persons on crutches, or persons in wheelchairs, said the Consejo Nacional de Vialidad. The projects cost $1.3 million.
Engineers chose the elevators because in some cases there was not sufficient public land to put in ramps, the agency said.. The elevators will be under 24-hour surveillance by cameras. The bridge at Hospital México at least had been the scene of many robberies.
