This photo taken April 14, 2014, shows one section of the $500 million I-75 Phase II modernization project which is under way in Dayton, Ohio. On the road in a tour bus this week, Transportation Secretary Anthony Foxx is urging Congress to quickly approve legislation to pay for highway and transit programs amid warnings that the U.S. government’s Highway Trust Fund is nearly broke. If allowed to run dry, that could threaten to set back or shut down projects across the country, force widespread layoffs of construction workers and delay needed repairs and improvements.
