The city of Igualada (Barcelona) has a new access from the C-37 highway. The works, executed by Extraco in a joint venture, included a +1-kilometer-long road, with four traffic circles and a unique metal viaduct over the Anoia River, with three spans and a central arch over the main one. Two of the traffic circles, each 50 meters in diameter, serve as a connection with the C-37, in the section between Vilanova del Camí and Igualada.

The road crosses the Riera Garrigosa with a 10.70-meter-wide road deck and the Fasina road with another traffic circle of similar dimensions to those already mentioned.

The viaduct over the Anoia River is a 116.4-long and 17.5-wide continuous deck, without interior joints. The type of span that covers the preferential flow area of the river corresponds to that of an arch with a bowstring cable-stayed lower deck, which in this case was resolved with a central arch with a height of approximately 7.8 meters above grade.

There is a final traffic circle that connects with the intersection of Rec and Misericòrdia streets, already in the city of Igualada.

The works were promoted by Infraestructures de la Generalitat de Catalunya, SAU.
