The City of Eugene's long term vision includes a transportation system that is balanced, accessible, interconnected, and environmentally responsible. With these requirements in mind, the City selected OBEC, in conjunction with Czech engineer Dr. Jiri Strasky, to design a unique pedestrian bridge to serve as a sweeping architectural landmark complementing nearby public amenities and recreational areas.
The signature 760-foot-long cable-stayed bridge serves as an important link in Eugene's popular trail system. Site constraints required a structure with a slender form from finished grade to soffit and a small footprint.
The proximity of the four-lane-wide divided highway and crossing geometry greatly limited the base area available for the central cable-stay support pylon, which was solved by using an innovative delta or "V" shape to minimize its footprint. The convenient and cost-effective precast segmental concrete deck panel design allowed the design team to meet Delta Highway traffic clearances that prohibited daytime lane closures and construction of falsework.
