The latest issue of the magazine Cimbra, published by the Spanish Association of Civil Engineers, features an in-depth report on the new southern access road to Igualada (Barcelona), a project executed by Extraco on behalf of Infraestructures de Catalunya.

Written by Francisco Javier Prego Martínez, the article focuses primarily on the distinctive steel viaduct spanning the Anoia River. The structure consists of three spans and features a central arch over the main span. It has a continuous deck measuring 116.4 meters in length, free of internal expansion joints, and a width of 17.5 meters. The span crossing the river’s main flow channel adopts a bowstring arch configuration with a lower deck braced by the arch. In this case, the solution incorporates a central arch rising 7.8 meters above ground level. The article provides a detailed account of both the structural characteristics and the construction process of this singular bridge.

The project also included the construction of a road slightly over one kilometer in length, incorporating four roundabouts. Two of these, each with a diameter of 50 meters, connect to the C-37 at kilometer 64.3, along the stretch between Vilanova del Camí and Igualada.

The new road crosses the Riera de la Garrigosa via a 10.70-meter-wide deck and connects to the Fasina road through another roundabout of similar dimensions. The fourth roundabout links the intersection of Carrer del Rec and Carrer de la Misericòrdia within Igualada.
