Infrastructure problems have emerged in several of the World Cup's host cities before and during the tournament.
An overpass under construction collapsed onto a passenger bus in World Cup host city Belo Horizonte, about two miles from the city's stadium. The overpass stretches above a highway that connects Belo Horizonte's international airport to the stadium. Officials planned to investigate the accident.
By the morning of July 4, rescue workers had pulled a second body from the collapsed bridge section. Along with the two killed, 22 others were injured in the accident. Belo Horizonte canceled a July 4 outdoor viewing party for the Brazil-Colombia World Cup match.
The overpass that collapsed July 3 was part of Brazil's building spree to prepare infrastructure for the World Cup. Fewer than 10 of the infrastructure projects were finished in time for the tournament's start in mid-June, including the overpass. The cause of the collapse is unclear.
Authorities said one worker was killed and two others injured when a section of a monorail under construction collapsed. The 11-mile project is behind schedule, but aimed to connect the Congonhas airport with several local transport lines for the World Cup.
A crane collapsed in Nov. 2013 onto a 500-ton metal structure that broke through an outer wall of Sao Paulo's World Cup stadium, smashing rows of seats and landing on an LED panel spanning the stadium's exterior. The construction site manager said the crane was built according to procedure.
Two workers were killed in the Nov. 2013 collapse -- Fabio Luis Pereira, 42, and Ronaldo Oliveira dos Santos, 44. The collapse happened at lunchtime and most of the 1,700 stadium workers were not working. Eight workers have died during the construction of Brazil's 12 World Cup venues.
The regional labor authority of Sao Paulo ordered that construction at the Arena Corinthians stadium be halted pending a technical analysis of the project. Worker Fabio Hamilton da Cruz died after falling 25 feet while installing flooring. He is the third worker to die on the site.
