OHLA has won the contract to build a road and 1.5km tunnel in Chile’s capital city.
The €280m investment by Sociedad Concesionaria Autopista Central SA of the VíasChile Group is for a major road infrastructure project between two of Santiago’s main urban corridors: General Velásquez and Américo Vespucio Norte.
The project includes the construction of a 1.5km twin-tube mined tunnel under Cerro Lo Ruiz. The tunnel will feature two unidirectional tubes: the East tunnel (South-North), with two lanes along its entire length, and the West tunnel (North-South), which will begin with three lanes and then continue with two. Both tunnels will connect to the two main urban corridors through modern viaducts.
The project will create a new north-south connection from the General Velásquez corridor to the Américo Vespucio Norte highway. The works will be carried out in three sections: Section A, which includes construction of a viaduct and other structures to link General Velásquez with the new tunnel; Section B, which includes the twin-tube tunnel under the hill; and Section C, which is the execution of four viaducts on three levels to connect with the existing Vespucio Norte highway.
As part of a sustainable development approach, approximately 164,000m² of green, recreational areas will be created. In the municipality of Quilicura, a park will be built during the tunnel construction phase, while in the municipality of Renca two landmark parks are planned.
