San Diego was on President Donald Trump’s mind — and his Twitter feed — Tuesday night.

Why? His dream of building an improved wall at the U.S.-Mexico border is finally becoming a reality. Well, at least the models for what the wall could look like are becoming a reality.

Construction on prototype designs for the border wall began in September, and with work at the fenced-off site in San Diego’s Otay Mesa almost complete, Trump took to his favorite form of communication to show his excitement.

He shared this montage of construction work footage on Twitter.

In total, there will be eight prototypes for his proposed border wall. Four of the prototypes will be made of concrete while the other four will be made of alternate materials. All of the models will be between 18 to 30 feet high and 30 feet long.

As The San Diego Union-Tribune has reported, at least five prototypes have already gone up and the construction work has gone on with little interruption, protests or other opposition.

Here’s where you can find them in San Diego (the construction site is about 1.5 miles east of Enrico Fermi Drive):

The deadline to complete the prototypes is Oct. 26 after which U.S. Customs and Border Protection are expected to choose which design will be used. This is all going on despite a lack of congressional funding for the rest of the wall that Trump wants built.

But the president is still celebrating the progress he’s made, and many on Twitter were celebrating with him.
