Growing populations in mid-sized and large urban areas continue to put a strain on aging public transportation infrastructures. The global market for new passenger and urban rolling stock is estimated at more than $19 billion. Separate budgets have also been expanded for the maintenance and refurbishing of existing cars.
Over the past decade, infrastructure engineers have been cautioning municipalities and governing bodies across the U.S. about the deteriorating condition of the country’s bridges and dams. The average age of the 609,380 bridges in the U.S. is now nearly 42 years old.
