Features
The main span of the bridge will be 1,500 feet (460 m) in length, with a total span of 2,803 feet. It will be 86 feet (26 m) wide. Cables will stretch from the bridge deck to the tops of two A-shaped towers, which will reach 435 feet (133 m) above I-70. According to the Illinois and Missouri Departments of Transportation, the new bridge’s main span will consist of 1,000 miles (1,600 km) of 0.6-inch-diameter (15 mm) stay-cable strand, enough for nearly two round trips from St. Louis to Chicago. Nearly 15,000 tons of structural steel will be used, along with 8,600 tons of reinforcing steel. Some 90,600 cubic yards of concrete will be used in the foundation, deck slab, and towers. Upon completion, the bridge will be the third longest cable-stayed bridge in the United States.

Famous quotes containing the word features:
“The features of our face are hardly more than gestures which force of habit made permanent. Nature, like the destruction of Pompeii, like the metamorphosis of a nymph into a tree, has arrested us in an accustomed movement.”
—Marcel Proust (1871–1922)
“Each reader discovers for himself that, with respect to the simpler features of nature, succeeding poets have done little else than copy his similes.”
—Henry David Thoreau (1817–1862)
“These, then, will be some of the features of democracy ... it will be, in all likelihood, an agreeable, lawless, particolored commonwealth, dealing with all alike on a footing of equality, whether they be really equal or not.”
—Plato (c. 427–347 B.C.)
