The Mackinac Bridge, Straits of Mackinac, Michigan

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.


Akashi-Kaikyo 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.

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 world.


Verazzano 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.


Brooklyn 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 York

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 long

Golden 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 air. 

George 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.

Waldo-Hancock 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.
