Super Bridge DVD
PRODUCT DETAILS
Take a look at “the bridge of the future:” sturdy and stunningly graceful, the new Clark Bridge spands the Mississippi at Alton, Illinois, linking the old river town with the promise of prosperity. Now, in this two-hour special, you can see how they did it. Play sidewalk supervisor at one of the world’s most remarkable and risky bridge projects - a rare example of what is known as cable-stayed design, an innovative variation on the suspension bridge. Zoom in on every phase of the four-year construction (with time out for dredging a sunken barge and weathering the worst Mississippi flood in modern history). See divers lay intricate underwater foundations, builders erect massive towers in frigid temperatures, workers hang huge cables to support the roadway (300 feet up, and just a fraction of an inch to spare), and freak winds threaten to topple the entire structure before the last gaps are closed. 113 minutes. Grade 6 and up.
