It was 5am on the dot when traffic officials removed the barriers and traffic started flowing across the two Bailey bridges on the Circunvalacion, between Hatillo 8 and Pavas.
Rains had delayed the promised Monday opening.
Work crews worked over night Monday to lay down the asphalt over the installed structures spanning more than 50 metres (150 feet), a temporary fix to the growing problem underneath.
It was 10 days ago when a sinkhole by the side of the road forced Transport officials to close off one lane on the heavily travelled ring road on the west side of San José.
Last week Public Works minister Pedro Castro announced that the problem would take months to solve, and that two Bailey structures would be installed to move traffic while work continues below, similar to the situation on the autopista General Cañas several months back.
Now that traffic is moving again, the quesiton of who is to fix the problem begins.
The Conavi (national roads council) said on Monday, that on closer inspection, the problem is the responsibility of the water and sewer utility, the AyA.
