Secretary for Transport and Public Works Raimundo do Rosário has pledged to parliament the government would spare no effort to refine traffic conditions near the Pearl of the Orient roundabout. He hoped the conditions would improve when the road networks nearby further expand. It is expected the Light Rapid Transit’s East Line contract would be signed within three months and construction begin within four, he said. He also refused to remove the artifact built on the roundabout, one of several built to celebrate Chinese-Portuguese friendship.
