Construction has begun on the fifth border wall project of Donald Trump's presidency, replacing up to 14 miles (22 kilometers) of barrier in San Diego.
U.S. Customs and Border Protection said Tuesday that the first panels are in place to replace a steel-mesh fence with steel bollards up to 30 feet (9 meters) high. SLSCO Ltd. of Galveston, Texas, was awarded the $101 million contract in December.
It is the second layer of barrier in San Diego. Work on replacing the first layer is nearly complete, which is also 14 miles long and made of steel bollards up to 30 feet high.
Construction began three days after Trump declared a national emergency to build his proposed border wall with Mexico. Lawsuits have been filed over the emergency declaration.
