Calatrava bridges in Reggio Emilia, Suspension bridge in Reggio Emilia, Italy.

The Calatrava bridges in Reggio Emilia are three white-painted steel structures carrying Viale dei Trattati di Roma over the A1 motorway and its slip roads. The central bow-string bridge has a single axial arch 46 m high and a 221 m span, its deck hung from 50 pairs of cables; the two side cable-stayed bridges, 179 m long, rise from inverted-U pylons 70 m tall. The right pylon is a solid white wedge pierced by a circular opening.

The three bridges were commissioned by the municipality of Reggio Emilia from Santiago Calatrava in the early 2000s, as part of a plan to reorganise the northern access to the city along the A1 motorway and the future Milan–Bologna high-speed line. The central bow-string bridge was completed in 2006 and the two side cable-stayed bridges in 2007. The complex was inaugurated on 20 October 2007 in a ceremony attended by mayor Graziano Delrio, provincial president Sonia Masini and prime minister Romano Prodi.

The three bridges carry the name Viale dei Trattati di Roma and form part of the ensemble Calatrava called Le Vele, the sails, together with the planned wave-shaped A1 toll booth cover and the Mediopadana high-speed station. The bridges were inaugurated on 20 October 2007 in the presence of mayor Graziano Delrio, provincial president Sonia Masini and prime minister Romano Prodi.

The three bridges carry the Viale dei Trattati di Roma over the A1 motorway and the high-speed Milan–Bologna line at the northern entrance to Reggio Emilia. The central bridge has two lanes in each direction plus pedestrian walkways protected by laminated glass; the two side bridges have one lane per direction. The complex is reached from the A1 Reggio Emilia exit and links the city to Bagnolo and the exhibition area.

The suspension consists of fifty pairs of cables running in a hyperbolic pattern from the arch to the roadway, creating a fan-like silhouette. This arrangement makes the structure recognizable from several kilometers away across the flat plain and gives it an appearance reminiscent of a sail or harp.
