The Mexico–United States barrier is a series of walls and fences aimed at preventing illegal crossing from Mexico into the Southwestern United States. The border fence is not one continuous structure and is actually a grouping of short physical walls that stop and start, secured in between with a “virtual fence” which includes a system of sensors and cameras monitored by U.S. Border Patrol Agents. As of January, 2009, U.S. Customs and Border Protection reported that it had more than 580 miles (930 km) of fence in place.

Supporters claim that the barrier is necessary for controlling cartel border violence and collaboration with overseas terrorists. Opponents see it as an ineffective deterrent that jeopardizes health and safety, and destroys fragile ecosystems along the Rio Grande.

Close to the southern tip of Texas, a border wall suddenly ends. Its final post sits in a dry cornfield half a mile from the nearest bend in the Rio Grande river, the actual border with Mexico.

It would be easy to walk around it. Tires left by the border patrol rest nearby. Agents drag them behind trucks to smooth the cracked earth and check for footprints.

Unlike famous barriers such as the Berlin Wall or the Great Wall of China, the US version is not much of a wall. What stands inTexas is a fragmented series of fencing, composed of enormous steel bars embedded in concrete close together. The rust-colored thick bars that must reach a height of 18ft loom over the landscape, forming teeth-like slats that split farmland, slice through backyards, and sever parks and nature preserves.

There are miles of gaps between segments and openings in the fence itself. As a result of the Secure Fence Act passed in 2006, the government built some 650 miles of wall along the 1,954-mile US-Mexico boundary. While 1,254 miles of that border is in Texas, the state has only some 100 miles of wall.

Finishing the some 1,300 miles of border fencing would also be costly. According to a 2009 government accountability report, pedestrian fencing, meant to keep out smugglers and migrants crossing on foot, has run anywhere from $400,000 to $15.1m per mile, averaging $3.9m.

More recent construction has been even more expensive, with segments constructed in 2008 costing $6.5m per mile. If kept at this rate, the wall would cost nearly $10bn to complete just for materials, and challenging geography could bring it much higher.

“With every twist and turn of the Rio Grande and every steep terrain in Arizona, it would cost easily that much,” said Adam Isacson, a border expert for the Washington Office on Latin America.
