Crystal Bridge
Oklahoma County, Oklahoma City. Built 1988, 224 ft. long. A landmark acrylic-covered tropical conservatory spanning a public pond at the Myriad Botanical Gardens, fully renovated in 2022.
Crystal Bridge is a 224-foot cylindrical conservatory spanning a pond at the heart of the Myriad Botanical Gardens in downtown Oklahoma City, its acrylic-paneled tube form making it one of the most architecturally distinctive covered spans anywhere in the country. Built in 1988 as the centerpiece of the gardens, it houses a tropical rainforest environment complete with waterfalls, exotic plants, and a suspended walkway, all enclosed within a soaring transparent tunnel that carries visitors literally through a greenhouse over water.
Oklahoma has no 19th-century covered bridges — its covered-bridge stock is entirely modern, mostly private stringer spans on golf courses, ranches, and residential developments. Crystal Bridge, though far removed from the traditional timber-truss form, is the state's most significant and heavily visited example of a genuinely covered span over water, and it underwent an $11 million renovation completed in November 2022 that restored and modernized the structure for a new generation of visitors. It remains a beloved downtown Oklahoma City landmark, open daily as part of the free public gardens.
