A Composite Sketch
Engineers are using the lightweight advantages of fiber reinforced polymers to build short span vehicular bridges and pedestrian bridges, particularly in remote areas, such as national...
High-Performance Powder
The application of fundamental principles related to the composition, the making, and the thermal treatment of concrete resulted in the development of a new type of concrete with outstanding...
Mix and Match
The U.S. Navy wanted to expand operations at Pearl Harbor, which required a bridge from Oahu to nearby Ford Island. The bridge spans more than 4,000 ft, and combines a fixed bridge and...
Balancing Act
The cable-stayed $69 million Glebe Island Bridge in Sydney was built using a combination of one rolling frame and one form traveler instead of a more orthodox two or four form traveler...
Record Spans in Japan
The Japanese bridge authority was tasked in 1970 with overseeing a vast project to link to two main islands of Honshu and Shikoku. The project, scheduled for completion in 2000, comprises...
Positively Not Pedestrian
An elaborate pedestrian and bicycle bridge in Eugene incorporates a number of innovative engineering features to create an aesthetically pleasing structure to complement the surrounding...
Putting Polystyrene to Work
Geofoam, the generic name for block or low density cellular plastic foam solids used in geotechnical applications, has low density and good insulation properties, which makes it well suited...
Czech It Out (Available only in Structural Engineering Special Issue)
Bridge and transportation engineers and architects combined on the design of a unique bridge in a small city in the Czech Republic. The cable-stayed bridge only has one tower which is...
Casting Hot and Cold
Contractors and engineers battled the Minnesota winter to build a concrete segmental bridge with form travelers. Superstructure segments were poured in temperatures as low as -19F, using...
Rapid Redecking
A contractor replaced nearly 7,000 m� of steel grid roadway deck filled with microsilica concrete on the Canadian crossing of the Thousand Islands bridge system more than one year ahead...
Losing Ground
Unusual engineering approaches, careful studies of earth and water movements, and a multi-organizational project team that worked cooperatively lead to the successful replacement of the...

Keeping Tabs on Two Tunnels (available in Geoenvironmental Special Issue only)
Engineers devised a unique liquid level monitoring system to check vertical movements in 90-year old twin subway tunnels. Construction for the Boston Central Artery/Tunnel project requires...
All Decked Out
After 50 years of wear, the deck of New York City's Williamsburg Bridge was buckling and badly in need of replacement. In 1994, consultants recommended replacing the deck...
Climate Control
The Wisconsin Department of Transportation (WisDOT) has created its own customized weather information system to improve efficiency in its winter road maintenance operations. Intended...
Cable-Stay Conundrum
Wind- and rain-induced vibrations of cables on cable-stayed bridges are a relatively new phenomenon. While some observers report hearing about such vibrations ten or 12 years ago, typically...
Express Design
Milwaukee's high-stakes effort to win its share of the lucrative convention market hinges on its new Midwest Express Center, a 670,000-sq-ft exhibition and convention complex....
Mitigation of Void Development under Bridge Approach Slabs Using Rubber Tire Chips
The problem of void development under bridge approach slabs has been correlated to the use of integral abutment bridges (Schaefer and Koch, 1992). This void development then causes settlement...
Tire Shreds as Lightweight Fill for Embankments and Retaining Walls
Use of tire shreds in three highway projects is described. In the first project, tire shreds were used as a compressible inclusion to reduce pressures on a rigid frame bridge. Earth pressures...
