Construction for Trump's Border Wall Begins in Texas

(AFP) The United States began construction in Texas on Saturday of part of President Donald Trump’s border wall designed to curb illegal immigration, which is a security threat.

Running along four miles of the 2,000-mile border with Mexico, the new section will replace existing fencing along the boundary between El Paso, Texas, and Ciudad Juarez, Mexico, US Customs and Border Protection said in a statement.

“This new wall will be far more durable and far more effective in deterring would-be illegal entrants,” Aaron Hull, Chief Patrol Agent in the El Paso sector, said in the statement.

It said the existing fencing will be replaced by an 18-foot (5.4 meter) steel post barrier which allows Border Patrol agents to see through to the other side.

The $22-million project is to be completed in about seven months.

In April, the Border Patrol announced the start of construction of a 20-mile stretch of wall to replace an existing barrier in Santa Teresa, New Mexico.

Much of the border already has fencing or other barriers, but Trump has ordered a “contiguous, and impassable physical barrier.”

Congress has so far approved $1.6 billion of $25 billion Trump had sought for his wall.
