Bigger. Better. Safer.

Expanding the Houston Ship Channel is critical to safely and efficiently sustaining national energy security, domestic manufacturing growth, thriving U.S. exports, and expanding job opportunities.

It is one of the most vital waterways in the country, connecting the nation’s largest petrochemical complex to the globe. The waterway has more deep-draft ship visits than any other port in the country, and nearly 200,000 barge transits every year as well. As energy and manufacturing exports increase and vessel sizes grow, improving the channel is nationally important.

That national economic impact is significant: the Port of Houston drives $906 billion in annual national economic value, sustains more than three million U.S. jobs, and is the nation’s number one port in total waterborne tonnage.


About the Project

As the local sponsor of this crucial federal waterway, Port Houston is partnering with the U.S. Army Corps of Engineers  to expand the channel.

When complete, the Houston Ship Channel expansion – Project 11 – will widen the channel by 170 feet along its Galveston Bay reach, from 530 feet to 700 feet. It will also deepen some upstream segments to 46.5 feet, make other safety and efficiency improvements, and craft new environmental features.

With the help of our partners, we expedited the process to complete the work by 2027. Overall, Project 11 will make the channel safer, ensuring this waterway will continue to remain the national economic treasure it is today.

What is the “Texas Chicken” Maneuver?

This maneuver is unique to the Houston Ship Channel. Ships from opposing directions in the channel meet each other head-on but still safely pass each other, as hydrodynamic forces keep the vessels from touching! This maneuver is successfully performed every day, and it’s necessary in relatively narrow channels like ours. Even with the incredible skill this maneuver requires, there is no question that a wider channel is a safer channel.

The Houston Ship Channel Mega Study and Chief Engineer’s Report

Port Houston began planning the latest improvements to the Houston Ship Channel in 2010, working in collaboration with Congress, the Army Corps of Engineers and channel stakeholders.

With help from Port Houston, the Corps completed its five-year Project 11 feasibility study, the Houston Ship Channel Mega Study –  the next navigation improvements to the Houston Ship Channel system. In April 2020, the Chief of Engineers signed the final Chief’s Report for the project. You can read the Chief’s Report here.

Water Resources Development Act (WRDA)

Congress schedules WRDA legislation for passage every two years to provide the Corps with direction on projects and policy in all of its mission areas, including navigation, flood control and environmental restoration.

The Houston Ship Channel Expansion Channel Improvement project was authorized in the Water Resources and Development Act of 2020 as part of a larger legislative package passed by Congress in December.

On January 19, 2021, the Port of Houston was notified by the U.S. Army Corps of Engineers (USACE) that it was awarded a “new start” designation and $19.5 million in federal funds to begin construction of the project.
