Pedestrian Bridge Echoes Undulating Shapes of Tempe Environment
Tempe Town Lake Pedestrian Bridge, Tempe, Ariz.
Connecting Tempe Town Lake's north and south banks, this elegant four-span arch pedestrian bridge was integrated with the existing piers and abutment of a dam at the reservoir. The bridge superstructure consists of two 34-ft-high steel pipe crossing arches. The concrete deck is supported on steel floor beams and stringers that are bolted to the arch. Delivery and assembly of the four 175,000-lb bridge arches occurred just downstream from the dam. The sections were lifted into place by two cranes at night to avoid thermal expansion due to the desert's high ambient daytime temperatures.
Design inspiration came from the undulating shapes of the Salt River and the geometric patterns of the adjacent Tempe Center for the Arts. The tensioned fabric and blue lighting compliment the lake and give the bridge added character.
