The Biden administration on Wednesday announced the release of $14 billion to the Army Corps of Engineers to fund 500 projects, with a focus on easing supply chain problems and addressing climate change.

The spending stems largely from President Joe Biden’s $1 trillion infrastructure deal, and the administration is trying to show how the projects will improve supply chain backlogs.

There are three specific projects tied to reducing supply bottlenecks by making it easier to transport goods, according to a White House fact sheet. U.S. ports have struggled to manage the inflow of container ships and move containers onto trucks as the economy recovered from the pandemic, resulting in delays in sending goods to consumers and higher prices.

Among the projects being funded for the Army Corps of Engineers is $858 million to replace locks on the Ohio River so that water levels are high enough for large cargo ships. Locks are enclosures that help to raise and lower water levels and make it easier to navigate waterways on uneven terrain.

Wednesday’s announcement includes $470 million for construction of a huge, new lock at Michigan’s Soo Locks that is key for shipping iron ore. There are also investments at the Port of Long Beach in California and Norfolk Harbor in Virginia to accommodate more shipping.
