First glimpses of Trump's border wall prototypes

Eight prototypes for Donald Trump’s U.S.-Mexico border wall are now complete, forming a line near the border in San Diego, California.

Trump has asked Congress for USD $1.6 billion to replace 22.4 kilometres of wall in San Diego and build a 96-kilometre wall in Texas' RioGrande Valley.

About 1,052 kilometres of single-layer fence already exists along the 3,143-kilometre border, plus 82 kilometres of double- and triple-layer fence.

Nevertheless, U.S. Customs and Border Protection awarded eight contracts to six companies to build the prototypes, at a cost of between $320,000 and $480,000 each.

They stand between 5.5 and 9 metres tall, and are made from concrete, metal or a combination of both. The walls vary in thickness, slope and colour.

Some were built with slat-like bars on the bottom for border officers to see through. One has sharp spikes resembling cactus spines running along the top.

Border Patrol spokesman Theron Francisco said there have been several illegal crossing attempts at the site since work began on Sept. 26.

Now that construction is complete, the walls will be tested see if they meet anti-climbing, anti-scaling, anti-digging and safety criteria.

The administration hasn't said how many winning prototypes it will pick.
