这座行人天桥位于草木茂盛的奥斯丁湖畔，它连接了主屋和一座新建的客房。桥的设计灵感来源于湖畔的芦苇等本土植物。这座桥是轻量化免维护设计，与湿地内的设施很好的结合在一起。桥接处芦苇交织在了一起并且几乎覆盖了桥面，掩盖住了桥并且使得这座桥的桥接处几乎不可见。这座桥由三部分组成：
上层结构：主跨度为80英尺，横跨了100英尺的拱结构。它由五个嵌套的五英寸管道组成，这些管道在主拱结构和岸边桥墩的弹簧桥接处连接并发散。
装饰和栏杆：管道支撑起了半英寸直径的由垂直向水平弯曲的金属条组成的护栏。不规则的长度和区间使得其更加贴近自然，而通过芦苇看去，原本很薄的上层结构看起来就更薄了。扶手则是一根由金属环固定的长索连接到了弯曲的护栏上。
桥墩：本地的石板材垂直层叠来建造出了桥墩的坡道。深深的刮缝为金属护栏创造了新的韵律。为了进一步的贴近自然，金属条仅经过了初加工，并将会与石板和绳索扶手一起经历自然风雨的磨砺。

Located on a densely vegetated site in Lake Austin, the pedestrian bridge connects the main house on the property with a newly constructed guest house. With a design inspired by the reeds and other native vegetation that cover the shores of the lake, the bridge is a light and maintenance-free structure that is well-integrated within its wetland setting. The bars/reeds intertwine at the abutments and “grow” over the bridge, camouflaging it and transforming the bridge into a symbiotic, almost invisible link. The bridge is composed of three elements:
Superstructure: The arch structure spans 100 feet with a main span of 80 feet. It is composed of five nested five-inch diameter pipes that diverge gracefully between the spring-point of the main span and the abutment at the beginning of the bridge.
Decking and Railing: The pipes support 1/2” diameter bars which become both decking and guardrail via a simple field bend from horizontal to vertical. The irregular length and close spacing of the bars recall the native reeds of the site, and the thin profile of the superstructure is made thinner when viewed through the visual veil of the reeds. The handrail consists of a rope secured with steel wire rings to a 1×1 horizontal tube welded to the vertical bars.
Abutment: Native stone slabs are layered vertically to create the ramps at the abutments. Deep raked joints recreate the rhythm of the steel bars of the deck and railings. To further incorporate the bridge with its natural setting, the steel is left unfinished to weather, just like the rope handrail and the stone ramps.
