The Green Bridge is located on the Southern Branch of the Castile Canal, in the municipality of Cigales (Valladolid), at kilometer 133.920, between Lock 40 and Lock 41. Its interest lies in showing the evolution of the canal and the coexistence between historical and contemporary solutions, maintaining the essential function of crossing over the channel.
This is a bridge designed to span the canal, with a deck made of prestressed elements that meets current usage needs. It measures approximately 6.50 meters long and 3.40 meters wide. It lacks parapets and railings, which emphasizes its functional character. The abutments are made of concrete, although some original masonry blocks from the previous historic bridge are incorporated into the abutment remains, allowing one to recognize the layout and history of the earlier structure. This partial reuse underscores the enduring value of the Canal de Castilla as a living infrastructure. The bridge’s state of preservation is that of a modern structure in service, while the preserved historical remains are fully protected due to their heritage value as an original hydraulic work.
For visitors, the Puente Verde (Green Bridge) offers a unique opportunity to understand how the Canal de Castilla has adapted over time. Integrated into an open, agricultural environment, it invites reflection on the overlapping of eras and allows visitors to enjoy a section where tradition and contemporary engineering engage in a natural dialogue.
