Letters have been sent by the Coalition for More Efficient Ports to President Donald Trump and senior politicians calling for greater investment in port infrastructure, as part of the much publicised US infrastructure investment plan first ann

The letter states: "Outdated infrastructure at our nation's ports threatens to interrupt the supply chain and ultimately the American economy. This critical infrastructure challenge must be met by increased public and private investment in US ports."

According to the coalition, traditional federal infrastructure funding programmes generally are not comprehensive enough to support the size and scale of investments needed at US seaports, but the time has come for that to change.

The letters have been sent at the same time as the US Government is expected to commence work on strengthening and rebuilding the nation's transportation infrastructure via a ten-year USD1 trillion spending plan, as was announced during President Trump's presidential campaign.

The coalition consists of three of the largest ports in the USA - Los Angeles, Long Beach and New York/New Jersey - plus the two largest marine terminal operators - Ports America Group and SSA Marine - as well as the Agriculture Transportation Coalition (AgTC) and the Retail Industry Leaders Association (RILA).
