deep channel separating the two parts of Willemstad, capital of Curaçao, in the Netherlands Antilles. The bay is a narrow waterway about 1 mile (1.6 km) long and from 300 to 1,000 feet (90 to 300 m) wide. The south end opens into the Caribbean Sea; the north end opens up into the Schottegat, a giant, deep lagoon that serves as a harbour and seaplane anchorage. Spanning Sint Anna Bay is the pontoon Koningin Emma (“Queen Emma”) Bridge, linking the two parts of the city. A newer fixed bridge vaults 160 feet (50 m) high over the bay and contains a four-lane highway.
