A few changes to traffic management on Yanggao Road S. in Pudong will be implemented from Saturday when work on a six-lane tunnel underneath it is due to start, police said yesterday.

The tunnel, linking the bridge over Pujian Road in the south with the underpass at Century Avenue in the north, is an ambitious project that is expected to significantly improve traffic flow on Yanggao Road between Nanpu Bridge and Yangpu Bridge by eliminating traffic lights.

Police predict more congestion on the already busy street during the construction project, but hope the new plan will alleviate it in future.
