BOA VISTA

city, capital of Roraima estado (state), northwestern Brazil, situated on the west bank of the Branco River, a tributary of the Negro River. Boa Vista was given city status in 1926 and was made the capital in 1943, when the territory (from 1990, state) was created. The city and its municipality are potentially rich, but they are isolated. Diamonds, gold, bauxite, and cassiterite are mined in the area; income is also derived from forest and animal products. Manufactures include petroleum and alcohol fuels made from sugarcane and cassava, metallurgical products, and construction materials. A thermal-electric plant serves the city, and an antenna was installed in 1975 for satellite telephone connections. Boa Vista is accessible by shallow-draft river vessels or by air; it is linked by road with the Caracara and Manaus river ports. Paved roads link Boa Vista, an important frontier military outpost, to the northeastern part of Roraima state. The town has air service to Guyana. Pop. (1985 est.) 66,357.
