Ports and inland waterways need an additional $6 billion to deepen harbors and overhaul river locks through 2020, says a new American Society of Civil Engineers report. Officials from ASCE and other groups say failing to improve infrastructure will hurt U.S. trade and job creation. Based on current funding, the study, released on Sept. 13, pegs 2020 maritime needs at $13 billion and spending at $7 billion. It says the funding gap would rise by $12 billion by 2040.
