President Joe Biden’s administration said Wednesday that it’s making hundreds of millions of dollars in federal funding available to overcrowded U.S. ports, in a bid to unclog supply chains and lower prices amid record inflation.

The Transportation Department said that it will make $450 million available to ports, to expand capacity and improve the flow of goods. The money will come from the $1 trillion-plus bipartisan infrastructure law that was passed last year.

Various U.S. ports have seen major congestion since the start of the COVID-19 pandemic and the bottlenecks have helped push up the cost of some imported goods.
