Macao’s Light Rapid Transit (LRT) network is entering a new phase of strategic expansion, with the government now studying two additional lines that would complete a full loop around the Macao peninsula. 
     The proposed West Line would begin at Qingmao Port and run through Fai Chi Kei and the Inner Harbour before terminating at Barra. This alignment would bring rail connectivity to several dense, older urban districts that currently rely heavily on road‑based transport. The second proposed line would originate in the large-scale reclaimed Zone A development area, linking the Outer Harbour, Nam Van, and Sai Van before also converging at Barra. Together, the two lines would form a continuous circuit around the peninsula, improving network redundancy and enabling more efficient passenger distribution.
     For construction and engineering professionals, the proposals represent a significant pipeline of potential civil works, including tunnelling, viaduct construction, station integration within constrained urban environments, and complex interface coordination with existing utilities and heritage areas. The alignment through older districts—particularly the Inner Harbour—will likely require careful geotechnical assessment, phased construction planning, and mitigation strategies to minimise disruption to residents and businesses.
