About the proyect

The overpass has a curved design, with a limited radius of curvature of just 25 m in a horseshoe shape, made with hyperstatic constant depth single beams of 0.90 m and Y-columns up to 7 m in length. The difficulty of post-tensioning and of executing and assembling the plates, which follow the curved shape of the deck, is particularly worthy of note.
