New Design Approach Saves Time, Money for Short-Span Steel Bridges

摘要

More than half of America's bridges are classified as city/county/township bridges-typically short spans. Of those, one-fourth are deemed structurally deficient or functionally obsolete, A team of researchers is testing a steel option for new and replacement bridges that could be constructed faster than concrete options. Judging from one trial in Iowa, the work could also cut about one-third of the cost in comparison to concrete.
