The temporary bridges over the collapsed section of the Circunvalación between Hatillo and Pavas finally opened Wednesday afternoon.
Officials quickly announced that the road would be closed from 10 p.m. to 5 a.m. In addition there are weight limits in force for trucks.
The highway began to collapse Aug. 24 and temporary bridges were installed badly. So the highway was closed in both directions Sept. 10.
There now are four temporary bridges, each carrying a lane of traffic.
Now workers will construct a permanent concrete solution underneath. There will be restrictions and delays until the final job is done.
Some 36,000 government employees will continue to work from 7 a.m. to 3 p.m. to avoid the peak traffic hours, the central government said. Some 80,000 vehicles a day use the Circunvalación, which is a four-lane bypass south of downtown San José from La Uruca to San Pedro.
