The Department of the Interior announced the completion and reopening of the rehabilitated Tidal Basin and Potomac River seawalls. Following a ribbon‑cutting ceremony, the newly restored area is now open for public access.  

The project addressed decades of wear and environmental stress, including ground settlement, frequent flooding, and aging infrastructure that had exceeded its intended lifespan. The work was funded by the Great American Outdoors Act. In total, more than 6,000 feet of shoreline were reinforced.  

“Today marks meaningful progress in preserving one of the nation’s most recognized public spaces,” said Secretary Doug Burgum. “This historic area is stronger, safer, and ready to welcome record visitors for America’s 250th anniversary and the generations to follow.” 

The Park Service says visitors will notice wider, safer, and more accessible walkways, along with extensive landscaping improvements. The project included the planting of 546 new trees, among them 353 cherry trees around the Tidal Basin and along nearby sections of the Potomac River.
