In the Serreria bridge, the pylon is curved backward and back-stayed to concrete counterweights in the roadway. The aesthetic effect of the Serreria bridge arises in part from the curved pylon and the 29 parallel cables supporting the bridge deck, accented at night by spot lighting of the cables and the pylon. The bridge deck has two carriageways, three lanes each for cars and one additional lane for a tramway, and a carriageway for only pedestrian and cycle traffic along the middle spine of the deck by the cable stays.
