Built in 2009, the Cesare Cantù Bridge is a 220-metre-long cable-stayed structure, comprising two 55-metre side spans and a central span measuring 110 metres. he deck is made of pre-stressed reinforced concrete with post-tensioned cables consisting of two 1.5-metre-high twin-cell caissons connected by an upper slab and post-tensioned crossbeams, 24 of which are located at the cable-stay anchor points. The deck is suspended by 48 stays arranged in 24 pairs, which are distributed between the central and side spans. Longitudinal pre-stressing is provided by post-tensioned cables housed in the caisson webs, with up to 18 cables per section. Each anchorage crossbeam has two cables, one straight and one curved upwards.
The work involved a special inspection of the post-tensioned pre-stressing cables, both in the webs and in the crossbeams, carried out in accordance with DM 204 of 01/07/2022, specifically Chapter 3.6, which sets out the guidelines for the assessment and monitoring of existing bridges.
