Aerial B-Roll footage of the newly-finished lock chamber at the John P. Murtha Locks and Dam in Monessen, Pennsylvania. Before the renaming, the facility was commonly known as the Charleroi Locks and Dam and officially named the Monongahela River Locks and Dam 4. The lock required 20 years of construction for a modernized chamber measuring 720 feet long by 84 feet wide, which replaces an older, smaller chamber. The construction also included a control tower with state-of-the-art systems and the potential to remote-control other facilities in the future. The new chamber expands the facility’s capacity to support commercial navigation throughout the region and the nation.
