In 2011, residents of Daybreak, a 4,200-acre master-planned community in South Jordan, Utah, will drive, bike or walk across the $2-million Brookside Bridge, which is made almost completely out of recycled materials. By then, project officials hope an environmental rating system for infrastructure will exist to quantify the bridge’s eco-friendliness.
This June, contractor Ralph L. Wads-worth Construction, Salt Lake City, took two days, 500 worker-hours and twin 275-ton cranes—owned by Mountain Crane Services, Herriman, Utah—to pin 40 half-arches together to create 20 full arches, spanning an 80-ft embankment and connecting the east side of Daybreak to the currently undeveloped west side.
