In a large urban intervention in Rio, decided to build the High Engenheiro Freyssinet, much better known by locals as High Paulo de Frontin.
This high follows the entire route of Paulo de Frontin Avenue in the neighborhood of Long River, and a link to the Red Line Tunnel Rebouças.

After the test was released to the overpass traffic and today is considered one of the most important of the River
