 Amazing Places!  Freeway Spaghetti Bowls  Existing
Abstract: High-Five because 5-levels pass over each other. Some points are as tall as a 12-story building, and about 500,000 commuters pass through it daily. The project required 37 permanent bridges and six temporary bridges to be built. Additionally, 300,000 square feet of retaining wall and 74,000 square feet of drainage pipe run along the interchange. In 2006, the American Public Works Association selected the interchange as one of its "Public Works Projects of the Year."
