Tema Bridges, Tanzania


As engineers, we have a significant responsibility to seek a more environmentally friendly approach to our work and to create opportunities for seeking different ways of undertaking the design through a more efficient use of the construction materials and a reduction of the overall energy consumption during the construction phase.

Mambo and Tema are small villages in the Usambara Mountains, in the remote district of Lushoto,

Tanzania, on the eastern side of Africa.

Our intention was to provide local builders with both the design of the three bridges and the finances to purchase the construction materials. We had also planned to provide direct construction assistance, via the volunteer labour of BG&E personnel.

With the help of the local community, three bridges were repaired and rebuilt. The three bridges were all 3.5 metres wide with clear spans each of 6, 4 and 2 metres.
