The US House of Representatives approved water resources infrastructure legislation that aims to improve America’s harbours, ports, waterways, flood protection and other water infrastructure.

"This important action will improve ports, dams, and waterways to facilitate commerce within our borders and connect US producers and consumers with the international marketplace," House Speaker Paul Ryan said.

The passage of the Water Resources Development Act of 2018 authorises critical infrastructure projects, including the construction of a second 1,200-foot lock at the Soo Locks complex at Sault Ste Marie, Michigan.
