Viaduto Santa Tereza, Cultural viaduct in downtown Belo Horizonte, Brazil.

Viaduto Santa Tereza is a 390-metre reinforced-concrete viaduct inaugurated in September 1929, designed by engineer Emílio Baumgart. It links the Floresta and Santa Tereza neighbourhoods to the city centre, crossing Avenida dos Andradas, the Ribeirão Arrudas, a railway line and a metro line. Its most noted feature is a row of parabolic arches.

Designed by engineer Emílio Baumgart and inaugurated in September 1929, Viaduto Santa Tereza was the first grade-separated crossing in Belo Horizonte. Its 390-metre structure was among the first in the city to use reinforced concrete, and it passes over Avenida dos Andradas, the Ribeirão Arrudas, a railway line and a metro line.

The viaduct's parabolic arches appear in Fernando Sabino's first novel, O Encontro Marcado, where the protagonist and friends climb them at great height. Carlos Drummond de Andrade reportedly climbed the arches soon after the 1929 inauguration and was threatened with arrest; he dared the guard to climb up, and the guard gave up. Since 2008 the space beneath the viaduct has hosted a Duelo de MCs.

Pedestrians can walk across the viaduct during daylight hours and enjoy views of the surrounding neighborhoods from above. The area around the structure is accessible year-round, though it is best explored in daylight and in company with others.

The parabolic arches appear in Fernando Sabino's first novel, O Encontro Marcado, where the protagonist and his friends climb them, risking a fall onto the railway below. Shortly after the 1929 inauguration, Carlos Drummond de Andrade also climbed an arch and was reportedly threatened with arrest; he dared the guard to climb up and make the arrest, and the guard gave up.
