The Houston Ship Channel's Project 11 Widening Finishes
Project 11 widens the channel by 170 feet along its Galveston Bay reach, from 530 to 700 feet, and deepens upstream segments to 46.5 feet so the largest container ships can pass one another. Dredging began in 2022; Port Houston finished its own segments in October 2025 and the US Army Corps of Engineers is completing the rest, with the spoil building bird islands, marsh and oyster reef.
- Project 11, the Houston Ship Channel expansion, "is widening the channel by 170 feet along its Galveston Bay reach, from 530 feet to 700 feet and deepening some upstream segments to 46.5 feet, alongside other safety and efficiency improvements, and crafting new environmental features"[1]
- Port Houston is the local sponsor, partnering with the U.S. Army Corps of Engineers on the federal waterway[1][2]
- Dredging began in 2022 and the partners are "expediting the process to complete the work in 2029"[1]; the Corps "will lead the remaining portions of the project, which are scheduled to be completed in 2029"[2]
- On 27 October 2025 Port Houston announced it had completed its own portion: "the project has reached its most important milestone dredging completion of the widening of the Galveston Bay reach from Bolivar Roads to Morgans Point. With this work done, Port Houston-led project dredging of the Houston Ship Channel is complete"[2]
- Work still outstanding at that point was the beneficial-use element - "some beneficial use aspects of the project remain under construction, including marsh areas that are being built with dredged material"[2]
- The scheme is divided into segments: Bolivar Roads to Redfish (about 11.5 miles, widened to 700 feet with bend easings), Redfish to Bayport (about 8.3 miles) and Bayport to Barbours Cut (about 5 miles), both of which are "currently not in the proposed federal plan, so must be built by local interests", plus widening of the Bayport and Barbours Cut ship channels to about 455 feet[1]
- Upstream, Boggy Bayou (BW 8) to Sims Bayou is widened to about 530 feet and deepened from 41 to 46.5 feet as far as Hunting Bayou, Sims Bayou to IH 610 is deepened from 37 to 41.5 feet, and IH 610 to the Turning Basin from 39 to a potential 41.5 feet with an enlarged Brady Island Turning Basin[1]
- The two links give different figures for the environmental features, because one states the whole project's plan and the other what the Galveston Bay dredging actually built: the overview promises up to 800 acres of marsh across three new marshes, bird islands "up to 20 acres in total" and "approximately 375 acres" of new oyster reef substrate[1], while the completion release says the Galveston Bay features "will ultimately include approximately 10 acres of bird islands, 276 acres of marsh, and 324 acres of oyster reefs"[2]
- The bird islands are supported by the Beneficial Use Group, which includes Port Houston and state and federal environmental agencies, and one triangular marsh "will have a bird island at each corner"[1]
- Air quality gains are claimed both ways: the expansion "is expected to improve regional air quality by reducing ship emissions... through more efficient vessel movements and avoiding congestion"[1], with vessel nitrogen oxide emissions "expected to be reduced by between three percent and seven percent" and dredges on the first three segments fitted with Tier 3 or Tier 4 engines or scrubbers[2]
- The widening is aimed at the "Texas Chicken" maneuver, "unique to the Houston Ship Channel", in which ships from opposing directions "meet each other head-on but still safely pass each other, as hydrodynamic forces keep the vessels from touching", a manoeuvre "necessary in relatively narrow channels like ours"[1]
- The navigation payoff is already visible: the Houston Pilots revised their Navigation Safety Guidelines so that "daylight restricted vessels now have up to an additional two and a half hours to transit into and out of port each day", and earlier phases let vessels "between 15,000 and 17,000 TEU - matching the capacity of the Panama Canal" call at Bayport Container Terminal[2]
- Planning began in 2010; the Corps finished its five-year Houston Ship Channel Mega Study, the Chief of Engineers signed the final Chief's Report in April 2020, the project was authorized in the Water Resources and Development Act of 2020, and on 19 January 2021 it received a "new start" designation with $19.5 million in federal funds[1]
- The two links size the channel's economy differently: the overview claims "$987 billion in annual national economic value" and "more than three million U.S. jobs"[1], while the completion release cites a 2022 third-party study giving "3.37 million jobs nationwide and ... $906 billion in annual economic activity", the newer and sourced of the two figures[2]
- The Corps recognised the 52-mile channel as the busiest waterway in the United States, "handling approximately 12% of the nation's total waterborne tonnage", serving more than 200 private facilities and eight public terminals; a draft Perryman Group study estimates Segment 1 alone will generate $60.95 billion in statewide benefit and 440,665 Texas jobs by 2040[1][2]
- The project won the 2025 Western Dredging Association Environmental Excellence Award and the 2025 Texas ASCE Outstanding Civil Engineering Achievement Award[2]

Port Houston’s own release dating the halfway mark this pin’s description rests on: "Port Houston-led project dredging of the Houston Ship Channel is complete", with the Galveston Bay reach widened from 530 to 700 feet, while "some beneficial use aspects of the project remain under construction". The 2029 date is for the whole of Project 11, not this portion.[1]
