The Tunnel of Tabua, which was undergoing work with a view to comprehensive repair, reopened fully to traffic this afternoon, June 18, and users can move without restrictions.
It is recalled that the Tunnel of Tabua was damaged after a fall of stones occurred on the 21st of January, which caused damage to the reinforced concrete structure that served to protect the road, leading to the rupture of the vault and the armor. The sanitation of the slope followed, causing the fall of rock masses that were unstable, removal of blocks that were deposited on the protection structure, replacement of damaged light fixtures and placement of a metal structure for temporary protection. The full repair operation of the structure was resumed in May, after the completion of the manufacture of the mold and metal structure to support the execution of the necessary works.
The work was carried out by VIAEXPRESSO, SA and included the removal of the temporary protection structure, repair / rehabilitation of the vault, with the removal of damaged parts, replacement and reinforcement of reinforcements, preparation and assembly of the mold and its concreting.
