As part of the modernization of road access over the Río Grande, Compañía Minera Yanacocha replaced an embankment with culverts with a higher-capacity structure: the S-27 Bridge, supported by two 10-meter-high abutments. To ensure abutment stability and durability under local hydraulic conditions, a mechanicall stabilized earth (MSE) system with welded wire mesh facing was executed.

The first four meters from the base were protected with shotcrete, reinforcing the structure against shear forces generated by water flow. This integrated solution significantly enhanced abutment protection, ensuring structural performance and operational continuity of the mining access under demanding conditions.
