The photo above is an aerial view of Monongahela River Locks and Dam 4 near Charleroi, Pennsylvania, July 21, 2023. The facility is one of nine navigation structures on the Monongahela River that provide navigation from Fairmont, West Virginia, to downtown Pittsburgh. The U.S. Army Corps of Engineers started constructing the lock at Charleroi in 1931 and finished in 1932. The project became operational Aug. 14, 1932. The most recent construction at the facility began in 1994 to replace the main chamber with a new lock measuring 720 feet long and 84 feet wide. Charleroi is located at river mile 41.5.

The U.S. Army Corps of Engineers Pittsburgh District is hosting a public information session to provide an update on the Lower Monongahela River Project as it nears the final phase.

WHO: The U.S. Army Corps of Engineers Pittsburgh District (USACE)

WHAT: This public information session is a forum for the community to learn about the project’s progress and future, and address community questions. It will consist of a 60-minute presentation followed by a question-and-answer segment.

Stations will be available after the presentation for community members to engage district experts one-on-one about topics such as the project’s history, current status, river levels, potential effects to nearby residents’ personal property, and upcoming project activity.

“Many of these improvements go unnoticed by the residents and communities bordering the river,” said Steve Fritz, the district’s megaproject program manager. “However, there will be noticeable changes to river levels in 2024.”

In 1994, USACE began modernizing locks 2, 3 and 4 on the lower Monongahela River in the Braddock, Elizabeth and Charleroi communities, respectively. USACE will begin removing Monongahela River Locks and Dam 3 in mid-2024. Removing Locks and Dam 3 is the final phase of the project after completing construction work at Locks and Dam 4 in Charleroi. The initial phase completed in 2004 and included major construction work at Locks and Dam 2 in Braddock.

“This signifies the culmination of 30 years of engineering and construction efforts to modernize the navigation facilities on the lower Monongahela River,” said Fritz. “In addition to providing reliable river navigation for the next century, this project will return more than $200 million in annual benefits to the region and nation.”

More information about the project and related documents are available at

WHEN: 7 – 9 p.m., Tuesday, Dec. 12.

WHERE: Elizabeth Borough Firehall, 107 Market Street, Elizabeth, PA 15037

WHY: Public meetings are important opportunities for communities to learn about, provide feedback, voice concerns, and share information about district activities and objectives. Locks and Dams 2, 3, and 4 on the Monongahela River in Allegheny, Washington and Westmoreland counties are the three oldest currently-operating navigation facilities on the Monongahela River. These locks experience the highest volume of commercial traffic on the entire Monongahela River navigation system, and the pools created by these facilities provide industrial and municipal water and are popular with recreational boaters.


General Information:

Pittsburgh District’s 26,000 square miles include parts of western Pennsylvania, northern West Virginia, eastern Ohio, western Maryland, and southwestern New York. Our jurisdiction includes more than 328 miles of navigable waterways, 23 navigation locks and dams, 16 multi-purpose reservoirs, 42 local flood-protection projects, and other projects to protect and enhance the Nation’s water resources, infrastructure and environment.
