Through the end of 2009, investments by the American Recovery and Reinvestment Act (ARRA) in public transportation have created almost twice as many jobs per dollar as investments in highways – and the advantage is growing. The most recent data from states shows that every billion dollars spent on public transportation produced 19,299 job-months, compared to 10,493 job-months for every billion spent on highway infrastructure. Public transportation projects create more jobs than road projects because they spend less money on land and more on labor, and because projects are often more complex, whether laying track or manufacturing vehicles.
