Highway officials just opened the new underpass at Paso Ancho, and now they are closing it for about four hours tonight.
This the six-lane underpass that replaced the traffic circle at Paso Ancho, also known as Guacamaya due to the nearby auto parts complex by that name.
The Consejo Nacional de Vialidad said closing the highway was necessary so that experts from the Universidad de Costa Rica could conduct tests on the quality of asphalt placed on the roadway. The experts are from the Laboratorio Nacional de Materiales y Modelos Estructurales.
The roadway will be closed at 8 p.m. and remain that way until midnight at the latest, said the highway agency.
This is the project on the Circunvalación where the traffic circle used to back up vehicles for miles. The roadway loops around the southern part of San José from La Uruca to San Pedro.
Officials have promised to eliminate the last traffic circle at Zapote in the next two years. The circles were built for a time when there was less traffic.
