In 1933, the New Alcántara bridge was opened in Toledo, with a total length of 79 metres, including abutments. Strong walls were built at the ends, resting on solid rock with buttresses. The bridge has a single segmental arch with a span of 43.30 metres, which rests on the bases of abutments on overhanging protruding parts. The level of the floor is 15 metres from the mean level of the river surface. The arch has a thickness of 1.23 metres at the keystone and 1.83 metres at the bases, made entirely of solid concrete. The bridge has an undoubted value in a World Heritage city, close to the Puente de Alcántara.

The bridge, with a clear width of 7.00 m, was designed exclusively for vehicle traffic, with two 3.50 m lanes and no area for pedestrians or cyclists.

The work involves extending the bridge platform to a width of 11.70 metres, creating pedestrian crossings on the sides and leaving the current bridge section for vehicle traffic. The extension is symmetrical and will be carried out with 12.00 m wide prefabricated concrete slabs supported on the existing structure and a lightweight concrete slab “in situ”.

Rigorous studies have been carried out on the structure to check its resistance to the increased load that the extension entails. During the work, various pathologies that the structure suffered from have been corrected. This has led to the foundations being reinforced by means of a micropile screen, which is difficult to implement due to the current of the Tagus River.

Every aesthetic detail of the extension has been carefully considered to make it compatible with the responsibility of the project next to the historic centre of Toledo, and it has been provided with artistic lighting.
