The administration is seeking to add hundreds of miles of barriers before President Donald Trump leaves office, but private property claims, difficult terrain, environmental restrictions and complex federal contracting could determine whether its construction targets are reached.

President Donald Trump’s renewed effort to expand the southern border wall has moved beyond the question of whether additional barriers should be built and into the more complicated task of acquiring land, awarding contracts, resolving lawsuits and clearing regulatory obstacles across thousands of miles of varied terrain.
Administration officials have set a goal of placing barriers along approximately 1,400 miles of the U.S.-Mexico border by the end of Trump’s term. The plan calls for 775 miles of new wall by the end of 2027, followed by additional secondary barriers and waterborne infrastructure through the end of 2028, according to Newsmax.
Reaching those targets will require far more than delivering steel and concrete to construction sites. The proposed system crosses deserts, rivers, ranches, wildlife refuges, floodplains, parkland and privately owned property stretching from California to Texas.
Each section can require surveys, access roads, engineering studies, environmental reviews, land negotiations, federal contracts and legal authority to enter or acquire property.
At least three principal federal agencies are involved in the process: U.S. Customs and Border Protection, the U.S. Army Corps of Engineers and the Justice Department. Depending on the location, federal officials may also need to coordinate with wildlife, environmental, historic-preservation, park, tribal, state and local authorities.
The Department of Homeland Security has authority to waive numerous environmental and preservation laws to expedite border construction. That power does not extend to private property rights, leaving eminent domain as one of the project’s most significant and time-consuming obstacles.
The problem is particularly acute in Texas, where much of the international boundary passes through privately owned ranches and other property rather than federally controlled land.
In the Big Bend region, approximately 400 landowners reportedly received federal access letters warning that condemnation proceedings could be initiated if the owners and government were unable to reach voluntary agreements.
Such proceedings allow the federal government to seek property for public use while compensating the owner, but disputes over access, valuation and the scope of the proposed acquisition can remain in court for extended periods.
The administration’s construction timetable may therefore depend as much on land negotiations and litigation as it does on funding or engineering capacity.
The challenge is especially pronounced along South Texas river frontage, where the international border follows the Rio Grande and proposed construction can affect farms, ranches, residential properties and access to the water.
The federal government must negotiate with property owners or pursue eminent domain cases before contractors can enter some locations and begin work.
Farther west, the obstacles change. Construction crews face rugged desert, isolated ranchland, mountains and long distances from established roads and material suppliers.
Congress provided the administration with substantial funding intended to address financial constraints that slowed earlier border projects. The One Big Beautiful Bill Act, signed July 4, 2025, allocated $46.5 billion for barriers and related border security infrastructure.
The White House said the appropriation would allow the government to resume projects that were delayed or halted during the Biden administration while moving forward with hundreds of additional miles of construction.
Publicly available progress reports show that contracts are being awarded, though the larger construction targets remain dependent on land access and legal clearances.
PolitiFact reported June 25 that Customs and Border Protection had awarded 11 contracts financed through the 2025 law. Completing the administration’s goals for 2027 and 2028, however, will require contractors to maintain a pace that may vary substantially from one border corridor to another.
The government cannot treat the entire southern boundary as a single construction site. Every segment presents different geographic, legal and environmental conditions.
In the Rio Grande Valley, those tensions have included federal wildlife protections. The Texas Tribune reported that former Homeland Security Secretary Kristi Noem waived provisions of the Endangered Species Act and other laws to accelerate construction across 13 tracts within the Lower Rio Grande Valley National Wildlife Refuge.
Supporters of the waivers argue that ordinary regulatory requirements can delay urgent security projects for years. Critics contend that bypassing those laws places wildlife habitats, waterways, culturally significant areas and nearby communities at risk.
Big Bend has become one of the most politically and environmentally sensitive parts of the expansion effort because of its remote landscape, public parks and protected areas.
Earlier concepts involving a continuous 30-foot steel-bollard wall in the park region have been scaled back. Remaining proposals, however, still include enforcement roads, vehicle barriers, surveillance equipment and other infrastructure near some of Texas’ most scenic and environmentally sensitive territory.
Customs and Border Protection has said work near Big Bend National Park and Big Bend Ranch State Park remains in the planning stage while the agency concentrates resources on areas it considers higher priorities.
Construction is expected to begin this month in parts of the Big Bend Sector, where CBP plans to deploy a system it calls a “Smart Wall.” The approach combines selected steel barriers with cameras, sensors and improved road access rather than relying on a continuous physical wall through every portion of the region.
The Washington Examiner reported that the planned work will expand border infrastructure in selected areas while using surveillance technology and natural terrain elsewhere.
“CBP is not planning to construct a 30-foot-high barrier in Big Bend National Park, Big Bend Ranch State Park, or the Black Gap Wildlife Management Area,” the agency said.
CBP added that it would coordinate with park officials and use existing roads whenever possible to reduce the need for new construction through protected land.
The agency said physical barriers are anticipated in the Marfa and Van Horn regions. Other portions of the sector are expected to rely primarily on cameras, sensors, roads and geographic features that already make crossings more difficult.
The second-term project builds upon approximately 450 miles of border wall constructed during Trump’s first administration.
Trump has long presented physical barriers as a central part of his strategy to deter illegal immigration and drug trafficking. Administration officials and other border-security advocates argue that a wall does not have to cover every mile of the border to be operationally effective.
Under that strategy, barriers are intended to redirect migrants and smugglers toward locations where Border Patrol agents have better visibility, road access and tactical control.
The result is a border system that combines permanent barriers, vehicle obstacles, surveillance towers, cameras, ground sensors, patrol roads and natural terrain.
The administration’s broader goals remain ambitious. Constructing 775 miles by the end of 2027 would require the government to move contracts, surveys, land acquisitions and construction crews through numerous jurisdictions without lengthy interruptions.
The additional objective of reaching approximately 1,400 miles of barrier coverage before the conclusion of Trump’s term would require secondary structures and waterborne defenses to advance on similarly compressed schedules.
Even where Congress has supplied funding, the government must still obtain materials, conduct engineering work, establish contractor access and resolve any challenge involving environmental law or private ownership.
DHS can accelerate portions of the process by waiving certain federal statutes, but it cannot unilaterally eliminate a landowner’s constitutional rights or avoid the legal procedures required to take private property.
That distinction explains why construction may advance rapidly on federally controlled desert land while moving far more slowly across privately owned sections of Texas.
The border wall is consequently neither a single continuous project nor a uniform line progressing at the same rate. It is a collection of individual construction corridors, each governed by its own land titles, terrain, access requirements and legal disputes.
One segment may be delayed by a wildlife refuge, while another is held up by a condemnation case. Elsewhere, contractors may face flooding concerns, river access problems, historic-preservation issues or the absence of roads needed to transport equipment.
Trump’s experience as a developer does not eliminate those public-sector constraints. Unlike a private building project confined to one property, the border system stretches through multiple states and across land controlled by private owners, federal agencies and other public entities.
The administration has funding and has begun issuing contracts, but its ability to meet the 2027 and end-of-term targets will depend on how quickly officials can convert those resources into completed barriers.
For now, construction is moving forward one corridor at a time. Whether the administration ultimately reaches 775 miles of new wall by the end of 2027 and approximately 1,400 miles of total barrier coverage before Trump leaves office will likely be decided not only by the availability of money and steel, but by the pace of land acquisition, court proceedings and construction across the country’s most difficult border terrain.
