Highway collapses and opens crater near São Paulo subway construction

By Lucas Berti

A portion of the Marginal Tietê expressway — one of the busiest in São Paulo — collapsed this Tuesday morning close to construction works on a new subway line. The incident opened up a crater alongside the worksite, forcing authorities to close a 500-meter stretch of the highway, causing congestion. 

The São Paulo fire brigade announced that there were no casualties, though two construction workers are receiving care after coming into contact with dirty water spilled by the collapse. São Paulo transport authorities said that excavations made by a tunnel boring machine caused the rupture of a duct or sewage pipe, causing the construction to flood and open a crater.
