Macau Daily Times » With more than 300 concrete samples from the Hong Kong-Zhuhai-Macau Bridge (HKZMB) considered “problematic” by public authorities, said that the analysis had uncovered another “130 problematic test results, which are probably related to 55 public works projects,” but that these projects do not present a safety risk. HKZMB is a massive design-build project that will connect Hong Kong, Macau and Zhuhai, three major cities on the Pearl River Delta in China.
