A report out from the Department of Treasury this week reveals that fixing America’s roads and bridges will not only improve our drive to the store, it will help the country’s middle class and our long term economic health, too.

The new report (PDF) discusses the numerous benefits of investing in transportation infrastructure. Spending on infrastructure is one of the best ways to invest transportation funds. The fact that these projects create good, new jobs – and lots of them – is one big reason why. Yesterday’s report found that 72% of the jobs created by infrastructure spending are middle class jobs, defined as those which pay between the 25th and 75th percentile of the national distribution of wages. New jobs are a huge boon for the construction industry in particular, which is facing unemployment rates at nearly twice the national average.
