Dick, Executive Editor 2 | ASPIRE , Summer 2009 E D I T O R I A L A s ASPIRE™ continues through its second year of exploring sustainable design, our PERSPECTIVE in this issue looks at the condition of the nation's bridges as evaluated by the American Society of Civil Engineers (ASCE). Author Andrew Herrmann of Hardesty & Hanover is chair of the Advisory Committee for the preparation of ASCE's 2009 Report Card for America's Infrastructure, which gives America's bridges a "C." Although that grade may seem acceptable, it is the same rating bridges received in 2005, during ASCE's last evaluations. That means there has been no appreciable improvement. In fact, grades for "Roads" and "Transit" actually went down. Not surprisingly, ASCE suggests a commitment to increased funding must be made. They also propose a plan comprising five nationally-focused recommendations. Two of these are: 1) Promote sustainability and resilience and 2) Address life- cycle costs and ongoing maintenance. The details are included in the article beginning on page 14. Sustainability, Resilience, Life-Cycle Costs, and Maintenance State-of-the-ar t concrete bridges provide sustainable solutions. Recent issues of ASPIRE contain a PERSPECTIVE by an authority on sustainability. Plus, nearly every project report confirms our belief that modern concrete bridges help achieve this goal, with long-term durability, freedom from frequent maintenance cycles, rapid constructability, low environmental impact, and opportunity for aesthetic creativity. This Issue of ASPIRE Some unique capabilities of concrete are revealed in an article on the Bijou Street Bridge over Monument Creek in Colorado Springs, Colo. by Gregg Reese. By using post-tensioning to create four-span continuity, 60-in.-deep U-girders combine with an 8-in.-thick deck to create a main span of 148 ft with girders spaced as much as 22.8 ft apart. The article begins on page 18. An advantageous combination of concrete components—cast-in-place, double-cell box girder segments, precast I-girders with precast deck panels, and cast-in-place concrete in the substructure and deck—will provide long-term durability for the I-45 Galveston Causeway in Texas. The article starts on page 22. Frederick Gottemoeller, in his Aesthetics Commentary on the Vancouver Land Bridge, in Washington, says, "There are no obvious dividing lines between bridge and ramp or between ramp and site." Indeed the project, a pedestrian bridge connecting important historic and geographic attractions over a busy six-lane state highway, has been described as a landscaped interpretive work of art. The story of this unique project begins on page 26. The state of Louisiana Department of Transportation and Development has conducted more research on high-performance concrete than most other states. Faced with considerable environmental challenges, the state puts into practice what it has learned. Read about recent examples in the article on page 46. In a somewhat similar way, Washington County, Ore., is replacing its more susceptible bridges with state-of-the-art concrete structures. Using high- performance concrete and techniques that provide for rapid construction, the county is ever mindful of environmental issues such as bat habitats. Read their stor y on page 51. This issue of ASPIRE includes its special semiannual section, Maintenance, Repair, and Rehabilitation of Concrete Bridges. Beginning on page 39, this segment includes reports from across the country.
