Before and after: Peru plans to upgrade hundreds of bridges.

The country has some 2,227 bridges on its national road network of which 553 are managed by concessions and are sufficiently good condition to cope with 48t trucks.

Of those on roads that don't have concessions, only about 7% are estimated to be in good condition. More than 470 structures operate with loading restrictions. Others temporary structures that are unsuitable for normal traffic.
