Klickitat Trail was the key passage to the Columbia for many Native American tribes. With construction of Highway 14 and the railroad, this connection was severed for many years. Vancouver Land Bridge renews the link. The Land Bridge is part of the Confluence Project, a collaboration between Northwest tribes, civic groups and artists to celebrate the Lewis & Clark Bicentennial and the area’s rich history.
KPFF provided project management, structural and civil engineering, and surveying for this 190 ft x 40 ft curved pedestrian bridge. This serpentine bridge blends with its surroundings, meandering around wetlands, highlighting archaeological artifacts, and offering aesthetic and interpretive experiences that illuminate the area’s history.
Bridge design needed to comply with FAA height requirements for the nearby Pearson Airport; cross over WSDOT SR-14; cross under the BNSF Railroad; avoid archaeological artifacts and impacts to Fort Vancouver; and not compromise the future off-ramp from the I-5 Columbia River Crossing. The structure maintains a slender profile despite the large superimposed dead loads from landscaping soils. Innovative structural techniques to offset these soil loads efficiently include upturned, curved longitudinal girders that also serve to retain the landscape soils on the bridge and a voided cast-in-place concrete deck to reduce weight.
The project integrates many green elements, including stormwater storage and reuse for irrigation, stormwater planters, a rain garden, native landscaping, interpretive signage, and many architectural elements expressing the message of sustainability.
