The five-mile long bridge now fondly called "The big Mac", including the approach roads, were, at the time, the world's longest suspension bridge between cable anchorages. The bridge itself was designed by engineer Dr. David B. Steinman. Merritt-Chapman & Scott Corporation's $25,735,600 agreement to build all the foundations led to the mobilization of the largest bridge construction fleet ever assembled. The American Bridge Division of United States Steel Corporation, was awarded a $44,532,900 contract to build the superstructure. A.B.D. began its work of planning and assembly in 1953. In several U.S. and Canadian Steel mills the various shapes, plates, bars, wire and cables of steel necessary for the superstructure and for the caissons and cofferdams of the foundation, were prepared. The bridge was officially begun amid ceremonies on May 7 & 8, 1954, at both St. Ignace and Mackinaw City.

Bridges are very complex structures that must be carefully engineered using long-lasting and strong materials. Some of the materials that are used for bridge building includes stones, cement, steel, wood, and composites.
Over 35,000 tons of steel were used in construction of the Lupu Bridge. The Lupu Bridge is a through arch bridge over the Huangpu River in Shanghai, China, connecting the city's Luwan and Pudong districts.
Caleb and Thomas Pratt invented the truss bridge in 1844. Some of the materials that have been used in truss bridges are timber, steel, reinforced concrete, and iron.
When your building a bridge, you have to deal with questions like which materials should be used, how much force can be applied before the structure collapses, and how to construct a bridge with a greater ability to withstand wieght. --Stew Pidasole

I believe that the bridge you are looking for is the Mackinac Bridge. It connects Michigan and is used daily buy thousands of residents, visitors and travellers.
The current (1973) bridge is a prestressed concete box girder bridge.
If technology you mean "materials"that was used for the bridge, then I found a good answer on Yahoo! answers, just type in this: "What materials were used to make the golden gate bridge?" The question is answered by Horatio, and he had a pretty good answer.
metal(steel), bricks, concrete
They used prestressd concrete and steel
The material used to build the bridge was wood and steel
iron, steel, concrete, stone, wood, and composites are the most common materials used in bridge construction!
The current London Bridge is a pre-stressed concrete box girder bridge.
