It's funny to listen to the never-Trump crowd squeal how the wall is not happening and the President is breaking a major campaign promise. What's not funny is the volume of pro-Trump supporters who actually believe it and make stupid posts on social media.
Construction has been underway. The Army Corps of Engineers has been involved for the past few years (NYT article from July 2017):
The United States Army Corps of Engineers has begun preliminary preparations for the construction of segments of a wall in several places along the border with Mexico, the Department of Homeland Security said on Tuesday.
Engineers are drilling and taking soil samples to determine what type of barriers would be most effective in the different types of geography along the border, said David Lapan, a spokesman for the Department of Homeland Security.
The drilling and soil testing are taking place in El Paso; Santa Teresa, N.M.; Calexico, Calif.; and the Rio Grande Valley in South Texas. Mr. Lapan said the testing has been completed in El Paso and Calexico. The agency has identified the San Diego area and the Rio Grande Valley as priority regions for new border walls. The Corps will begin work in the San Diego area in August.
The drilling and testing come as Customs and Border Protection, the parent agency of the Border Patrol, continues to evaluate dozens of proposals that have been submitted by vendors for designs for a border wall.

Here's a short piece about how Los Indios, a small town in Texas, has greatly benefited from wall construction:

News spot on San Ysidro in San Diego:
The wall has been under construction and underway, despite resistance from the Republicans and Democrats in Congress, and Romney's spokespeople like Ann Coulter.
Getting past the coup attempt, and with funding not a problem, progress will move even faster. The new narrative by people with no engineering or border security experience is it's not really a wall. However, it's important to be able to see through the other side, and the slats are so close together that Ann Coulter on a juice diet couldn't slip through.
Another narrative is most of the construction is "replacement", as if that means construction isn't happening. If a fence or barrier that did absolutely nothing to keep out invaders is being ripped out and replaced, then that's new construction and now secured from easy access.
