Design
The bridge, over the Detroit River, had the longest suspended central span in the world when it was completed in 1929—1,850 feet (564 m), a title it would hold until the opening of the George Washington Bridge in 1931. The bridge's total length is 7,500 feet (2,286 m). Construction began in 1927 and was completed in 1929. The architect was the McClintic-Marshall Company of Pittsburgh, Pennsylvania.
The bridge is styled in a mixture of Art Deco and Streamline Moderne architectural designs, with some Gothic architecture blended in. It is made primarily out of steel; however, the two main towers on each side of the river are made of a steel-silicon alloy which rise up from concrete piers. The towers rise 386 feet (118 m) above the river, and plunge 115 feet (35 m) below the surface of the Detroit River. The bridge is made up of 21,000 short tons (19,000 tonnes) of steel, and the roadway rises as high as 152 feet (46 m) above the Detroit River. Only the main span over the river is supported by suspension cables; the approaches to the main pillars are held up by steel in a cantilever truss structure.
The only bridge sidewalk on the south side used to allow pedestrians and bicycle has been closed for decades (see painting and bridge deck repair below) in violation of the bridges charter. This was formally confirmed after the September 11 attacks. When the painting is being done on the south side of the bridge span, the sidewalk helps accommodate equipment and decrease the length of the lane that is cordoned off for painting.
Granite blocks, originally used on the U.S. side, were given to the Windsor Parks & Recreation Department, and now grace many of the pathways in Windsor parks

Famous quotes containing the word design:
“For I choose that my remembrances of him should be pleasing, affecting, religious. I will love him as a glorified friend, after the free way of friendship, and not pay him a stiff sign of respect, as men do to those whom they fear. A passage read from his discourses, a moving provocation to works like his, any act or meeting which tends to awaken a pure thought, a flow of love, an original design of virtue, I call a worthy, a true commemoration.”
—Ralph Waldo Emerson (1803–1882)
“Nowadays the host does not admit you to his hearth, but has got the mason to build one for yourself somewhere in his alley, and hospitality is the art of keeping you at the greatest distance. There is as much secrecy about the cooking as if he had a design to poison you.”
—Henry David Thoreau (1817–1862)
“Joe ... you remember I said you wouldn’t be cheated?... Nobody is really. Eventually all things work out. There’s a design in everything.”
—Sidney Buchman (1902–1975)
