PEDESTRIAN FENCING Steel anti-climbing plate 1.5m (5ft) high

Bollards: Closely-spaced steel posts filled with concrete and rebar. Gaps allow Border Patrol agents to see what’s happening on other side

Bollard-style fence already exists along large sections of border – use of steel makes repairs relatively easy if fence is breached

Height At least 5.5m (18ft). Barrier could go as high as 9.1m (30ft) depending on undulating terrain

Concrete foundation

Below ground Steel bollards embedded to depth of about 1.8m (6ft), with another 60cm (2ft) of concrete underneath to deter tunnelling
