Description
America's infrastructure is in dire straits according to the 2013 American Society of Civil Engineers (ASCE) Report Card, giving America a D+ average for all infrastructure categories. "The World Economic Forum's Global Competitiveness Report 2014-2015 ranks the U.S. 16th in quality of overall infrastructure" (Peters State). This paper addresses the need for investment in transportation infrastructure starting today, with a focus on bridges. The rates at which infrastructure is being built and maintained is not sustainable. Lack of funding causes states to practice deferred maintenance of infrastructure which ultimately results in higher overall costs. Timely maintenance and investment in current infrastructure is almost always the more economical approach. Despite conditions in Arizona, the rest of America is struggling with crumbling infrastructure. This paper stems from the Tex Wash Bridge failure on the Interstate-10 between California and Arizona in July 2015. A case study of four potential causes of the Tex Wash Bridge's collapse are discussed, along with several solutions that could have lessened the likelihood of failure. The condition of bridges are cataloged in the National Bridge Inventory managed by the Federal Highway Administration. In all reality, cost is not incurred at the instance of a bridge collapse, rather it is incremental throughout the infrastructure's lifetime. The impact of infrastructure failures are economic, social, and political. In the last decade, 33 short term fixes for project funding of roadways have been passed by Congress, none lasting longer than two years. The federal budget's underinvestment in infrastructure limits state departments of transportation ability to address high risk issues. Transportation is funded via the federal gasoline tax and vehicle license tax, along with state gasoline taxes. Unfortunately, the federal gasoline tax has not been increased since 1993. The Highway Trust Fund has subsequently faced insolvency in recent years. In 2011, America only committed 2.4% of its GDP to it's over 4 million miles of roads concluding that there is no interest to make transportation infrastructure a national priority. Currently, each state needs an average of $1 billion to address deficient bridges, and America needs $3.6 trillion to raise infrastructure ratings in the next five years. These needs can only be addressed at the federal level through long-term transportation legislation. It will require gaining investor confidence in tax spending, looking towards alternate funding such county taxes or toll roads, and capitalizing on the immediate interest generated by catastrophes. Mary Peters, former United States Secretary of Transportation, emphasizes the economic impact of underinvestment to foster political will, as opposed to focusing on America's crumbling infrastructure. Public safety and the economy are tied directly to the condition of America's infrastructure. For improvement on the national level, the disconnect between public understanding, engineering judgement, and political action must be remedied. The process starts by making America's infrastructure a national priority.
