威廉姆斯十字路口人行桥丨美国塔尔萨丨schlaich bergermann partner (sbp)

Project Year：2024

Category：Bridges

As part of the City of Tulsa’s vision for the improved Zink Dam area, schlaich bergermann partner (sbp) was asked to design a new pedestrian bridge that would provide a safe and modern crossing between the east and west sides of the Arkansas River and replace an existing bridge that was deemed structurally unsound and in need of major repair. 

The result is the 1,440-ft-long Williams Crossing, which is supported by eleven 120-ft-long arch spans and an approach span. The semi-integral bridge was designed with extremely slender deck-stiffened arches built from 3-1/4″ plate of weathering steel and is curved in plan. Optimized and structurally expressed steel nodes allow for the transfer of loads from the superstructure to the substructure where the arch spans meet. It is the longest arch-type pedestrian bridge in the United States and also the first multi-span, plate arch bridge built in the US.

This new symbol for Tulsa provides a connection to “Gathering Place,” an immense park designed by Michael Van Valkenburgh Associates, as well as links to the River Parks and Midland Valley Trails. The Williams Crossing is designed for both pedestrian and cyclist access and offers opportunities to stop and enjoy the dramatic river views with seating and lookout areas along the bridge deck.
