西灣大橋係澳門第三條連接澳門半島同氹仔嘅跨海大橋。呢棟橋係斜拉橋，設有上下兩層行車道。正常情況只會使用上層。只有喺澳門懸掛八號風球或更高嘅暴風信號，上層橋面關閉嘅時候，先會開放下層。
The Sai Van Bridge is the third sea-crossing bridge connecting the Macao Peninsula and Taipa. The bridge is a cable-stayed bridge with two levels of carriageways. Normally, only the upper layer will be used. The lower deck will only be opened when Typhoon Signal No. 8 or higher is hoisted in Macau and the upper deck is closed.
