Overview

Situated in Brazil's São Paulo state, the Tamoios Highway is a transport corridor upgrade scheme connecting existing highways of national significance.

With 85% of the route crossing an environmental protection area, the works include a combined 13 km of NATM tunnels, and 2.5 km of bridges up to 45 meters in height. The alignment spans a diverse topography, including sedimentary plains and steep mountainous terrain consisting of crystalline rock; whilst resulting in wide range of technical, environmental and logistic challenges. The project also incorporates tunnel T3/T4, the longest road tunnel in Brazil (5.55 km in length).

This talk will present and overview of the upgrade scheme along with methods and technology implemented to overcome the geotechnical challenges and reduce environmental impact. Additionally, logistical solutions developed for equipment and emergency access will also be discussed.
