The United States is making steady progress toward completing President Donald Trump’s long-promised southern border wall, with the main barrier expected to be finished by late 2027, according to Customs and Border Protection Commissioner Rodney Scott.

Speaking at an event hosted by the Center for Immigration Studies in Washington, Scott said the reinforced metal wall will run from San Diego to the Gulf of Mexico, with exceptions only in remote or naturally defended areas such as Big Bend National Park. He emphasized that the project includes secondary barriers along the Rio Grande River in Texas and will be supplemented by advanced electronic surveillance, sensors, and other technology by mid-to-late 2028.

The wall is designed to curb illegal immigration and narcotics trafficking, both of which have declined under stricter enforcement measures. However, Scott noted that smugglers continue to adapt by using tunnels, drones, and other methods to bypass physical barriers and monitor patrol movements.

The announcement reflects the Trump administration’s commitment to securing the southern border through a combination of physical infrastructure and technology, fulfilling a central campaign promise. Construction has accelerated in recent months as part of a broader strategy to restore sovereignty and reduce the flow of illegal crossings and fentanyl into the United States.
