Laguna Garzon Bridge by Rafael Viñoly: The bridge’s unusual circular road deck slow traffic and allows driverspedestriansand cyclists to appreciate panoramic views to one of the most beautiful and pristine coastal landscapes in Uruguay. The Garzón Lagoon is one of a series of environmentally sensitive bodies of water along Uruguay’s coast. The Ministry of Transport has long held an interest in developing a bridge over the 4,448-acre lagoonwhere it meets the coast and divides National Route 10. Crossing the lagoon previously was only possible in the summer months via rafts. Rafael Viñoly’s design was chosen for its alternative solution to a typical bridge structure–a 202-meter (663-foot) ring of road that sits over but does not disturb the transparent water and ecosystemslows traffic inherently and creates a pedestrian-friendly point of interest. Opened in December 2015the bridge’s 16 round concrete pillarsplaced 20 meters (65 feet) apartsupport two ramps and a central rotunda road across the lagoon. Pedestrian walkways on either side of the split traffic lanes give access to the structure’s central voidwhere visitors can sitfishand bathe in the water below.
Tall enough for boats to pass freely underneath and designed with the fewest number of pillars to avoid interference with the natural movement of fishthe bridge was carefully designed to be least destructive to its existing ecosystem. Designed as a “lagoon within a lagoon,” the circular shape reduces shadows on the water below. The structural profile also forces motor vehicles to slow while crossing and encourages drivers to take in the natural beauty of the area. Documented as an Important Bird and Biodiversity Areaa natural ecosystem that protects regional birds and their habitatsthe Laguna Garzón Bridge site is popular for birdwatching and clam harvestingand is surrounded by panoramic landscape views. The design of the bridge minimizes its environmental impact and creates an above-water public realm. Rafael Viñoly accepted the commission for the Laguna Garzón Bridge on the condition that the new bridge would signal the end of the National Route 10the main access road to several seaside resorts in the area. Firm Principal Rafael Viñoly lobbied Uruguayan government agencies to give the highway’s development power to local jurisdictions whose interests are more environmentally-centered.
