Brazil must invest BRL183.5bn ($99.1bn) on building and maintaining roads and bridges, an Institute of Applied Economic Research (IPEA) report said.

The report said the road network in the country had not improved despite a 290% rise in investment between 1999 and 2008.

The IPEA said the Brazilian government’s infrastructure plan in 2007 covered only 13% of the required investments in federal highways.

Brazil has 61,000km of paved roads under federal jurisdiction and nearly 70% need to be repaired.

The report has not included the 29,000km of roads under private or regional management in Brazil, according to Xinhua news agency.
