Bridging the Gap: Restoring and Rebuilding the Nationís Bridges
John Horsley (in): Tom Sorel (pf)
Offers information on the conditions, age and costs to repair and modernize the nationís 590,000 bridges as well as key examples showcasing new inspection and construction technologies. Key findings: (1) Within the next 15 years almost half of the nationís bridges will exceed 50 years of age, exceeding the life span for which they were designed. Even now, one in five are over 50; (2) With age comes decay. One in four of our bridges are rated as deficient, either in need of repair or in need of widening to handle todayís traffic; (3) New estimates show that more than $140 billion will be needed to fix them; (4) Soaring construction costs have whittled away the ability of states to address preventive maintenance and new bridge construction.
