Slope stabilization for the Chilina Bridge

Arequipa, the economic and political centre of southern Peru, features one of the longest bridges in the country: The 562 m long Chilina Bridge.

As approx. 80 % of the heavy goods vehicle traffic now bypasses the city, the centre of Arequipa is considerably relieved from traffic by the new bridge.
The project also includes two access roads. The northern road provides access to the Chilina Bridge from Avenida Chilina via a 60 m long tunnel that was built using the open cut method. The construction of the tunnel also required a slope stabilization of the lateral precut.
DSI Peru supplied more than 1,600 m of hollow bar soil nails in individual lengths of up to 6 m that were installed in layers. Following the soil nail installation, reinforcing steel mesh was applied, and the soil face was further stabilized by a layer of shotcrete.
