Brazilian President Dilma Rousseff announced investments of 5.4 billion reais (some $2.4 billion) in projects to expand the subway and urban train lines of Sao Paulo, which she justified as one more response to the protests that shook Brazil this summer.

The investments in improving public transport were announced at an event in Sao Paulo, the country's biggest city and from where the uproar for better public services spread across the country and had millions of irate Brazilians protesting in hundreds of cities.

Sao Paulo residents initially protested against the 0.20 real ($0.09) hike in bus and subway fares, and against the huge traffic jams that meant taking them as much as two hours to get to work.

"The protests in June were not just over those 20 centavos. They were for more rights. That's why we responded with the proposal of the five pacts, and one of those pacts was for urban transport," the president said.

"Offering quick, high quality urban public transport at a fair price is a challenge for all governments," she said.

Part of the funds announced Friday will be invested in expanding two of Sao Paulo's subway lines and another part will go to the construction of a railroad to the city's international airport, located in the neighboring municipality of Guarulhos and the busiest in the nation.

The funds will also be used for the moderization of 19 stations on Sao Paulo's metropolitan train lines. EFE
