Calzada de Tlalpan

Construction of the causeway began during the reign of tlatoani Itzcoatl in 1432.^[2] It was one of three that linked Tenochtitlan with the shores of the surrounding lakes.^[1] In 1519 it was used by conquistador Hernán Cortés to enter the city.^[3]

Since 1970, line 2 of the Mexico City Metro runs down the Calzada de Tlalpan's median after emerging from its underground section at San Antonio Abad station. The Xochimilco light rail continues down the Calzada after the metro's terminus at Tasqueña.^[1] Both transit systems follow the right-of-way of a former tram line.^[3]

For vehicular traffic, the Calzada ends at its junction with Avenida Insurgentes in the borough of Tlalpan, where Federal Highways 95 and 95D continue south to Cuernavaca, Morelos, and beyond.
