Supply-side solutions
Article Abstract:
Engineers and contrators have developed several innovative methods of bridge construction and repair. However, these ideas will remain on paper unless bridge owners allow them to materialize in their projects. Such innovative ideas are proposed for the repair of the Mathews Bridge in Jacksonville, FL, the Cooper River Bridge in Charleston, SC, and the Williamsburg Bridge in New York, NY. The US can also enhance its international trade by learning from their European counterparts and adopting an innovative infrastructure initiative that would allow American engineers to explore bridge design opportunities.

In the wet
Article Abstract:
The development of high-performance tremie concrete mixtures makes it possible to use large-diameter cylinder piles of steel and concrete in the construction of the underwater portion of bridges. These materials possess acceptable corrosion rates when used with sacrificial anodes, epoxy and polyethylene coating jackets. Work on bridges in America, Hong Kong and Bangladesh is going on with this new type of material. These materials are found to be excellent in bridge construction in regions rocked by frequent earthquakes as well as protecting against ship collisions and ice.

Scour power
Article Abstract:
A technique to determine scour in erodible rock helps engineers calculate rock scour and design better bridge foundations. The method relates the erosive power of water and the material's erodibility index. The erodibility index accounts for the material's strength, as well as the particular properties and shape of the rock. Scour occurs when the erodibility threshold is crossed.
