The bridge's main pylon stands at 158 meters, making it one of the tallest structures in the Monterrey metropolitan area.
It was designed by the architectural firm Oscar Bulnes Valero.
The project was part of a larger initiative to modernize cross-river transit infrastructure in the Santa Catarina basin.
The cable-stayed configuration was selected specifically to withstand high wind loads common in the mountain-adjacent valley.
Its construction utilizes a 'fan-type' cable arrangement to balance the suspension load across the deck.
The Puente Atirantado, officially known as the Puente de la Unidad, is a cable-stayed bridge spanning the Santa Catarina River that connects the cities of Monterrey and San Pedro Garza García. Inaugurated in 2003, it features a singular 158-meter tall mast that supports the bridge deck via high-tension steel cables. The structure design mimics the surrounding topography, specifically referencing the profile of the Cerro de la Silla mountain. The bridge serves as a major transit artery, featuring three lanes in each direction alongside dedicated pedestrian walkways. Its aesthetic prominence is heightened by LED illumination systems that are frequently adjusted for specific cultural observances. The bridge remains a significant piece of modern civil engineering in the state of Nuevo León.
The riverbank area below the bridge on the San Pedro side provides the best perspective of the pylon's height.
Walk the pedestrian path during the evening to see the bridge's integrated LED lighting in operation.
Exercise caution due to high-speed vehicle traffic immediately adjacent to the pedestrian walkways.
Choose a clear day to ensure the backdrop of the Sierra Madre Oriental mountains is visible.
Avoid standing near the edge of the bridge deck while vehicles are passing at high speed.
