The Mackinac Bridge, Straits of Mackinac,
The massive 5 mile long bridge was the longest suspension bridge in the world
when completed. With a main span length of 3800 ft. and towers that rose
552 ft. in the air, this project was was a monumental signature of the great
designer, Dr. David B. Steinman. The bridge was opened to traffic,
according to the schedule on November 1, 1957.
Bridge - Japan
The Akashi-Kaikyo Bridge, connecting Kobe on the mainland with Awaji on Awaji
Island, will be a huge three-span cable-stayed bridge some 3910 meters in total
length with a center span of 1990 meters. When completed, it will be the longest
bridge of its type in the world, surpassing the Humber
Bridge in the U.K. which has a center span of 1410 meters.
Humber Bridge - UK
The Humber Bridge is the worlds longest single span suspension bridge.
The structure is a civil engineering masterpiece with a design life of 120
years. When the Humber Bridge was completed in 1981, it surpassed the
Verazzano Narrows Bridge for the claim of the longest suspension bridge in the
Narrows Bridge - New York
The towers soared 650 feet above the water, while the double-deck roadway was
suspended 226 feet high. The main span stretched 4260 feet between
towers. These distances are so high and far apart that in designing
the bridge it was necessary to take into account the curvature of the earth.
Bridge - Brooklyn, New York
In 1866, John Roebling was hired as chief engineer for the design and
construction of the record-breaking span of the Brooklyn Bridge. On his
death bed in 1869, John asked his son Washington Roebling if he would accept the
lead position to finish the construction of the bridge. His son
courageously assumed the responsibility of completing the project.
Williamsburg Bridge - New
The 1,600-foot-long main suspension span for the Williamsburg
Bridge exceeded the previous record-holder, the Brooklyn Bridge,
by four and one-half feet. Compared to the main span, the
300-foot-long side spans are relatively short. However, the side
spans are supported not by suspender cables, but from steel arches
from below. From approach to approach, the bridge was 7,200 feet
Gate Bridge - San Francisco, California
After years of arguing about whether San Francisco, California needed this
bridge, which the opposition said was impractical to build. On Nov. 4,
1930 the public voted for the project to go ahead, and on Jan. 5, 1933
construction began. The main span of the bridge is an amazing 4200 feet,
with distinctive stepped-back towers that climb to 746 feet in the
Washington Bridge - New York
The George Washington Bridge Combines many advances in suspension bridge
technology. For example, flexible steel towers and a revolutionary
cable-spinning process to lay the pair of 3-foot-diameter cables that make up
the bridge deck. The George Washington Bridge was built in just four years
and was opened on Oct. 25, 1931.
Bridge - Maine
Maine's first long-span suspension bridge, is located near Bucksport,
carrying Route US 1 and Route 3 over the Penobscot River between the towns of
Prospect and Verona.
