(CNN)On his sixth day in office, President Donald Trump signed executive orders to begin construction of a wall between the United States and Mexico, making good on a campaign promise. He also announced he will boost deportation efforts and beef up border patrol resources along the border.

The 1,933-mile barrier cuts through towns, rivers and desolate terrain and across California, Arizona, New Mexico and Texas. Here's a look at how the US-Mexico border looks before the construction of the wall begins:
The border fence separates two sides of Nogales: Nogales, Mexico, on the right and Nogales, Arizona, on the left. In 2016, US Border Protection says it had 17,026 out of 19,828 agents posted along the Southwest border.
