There has been a very large double fence (with vehicle road and lights) in that exact sector for years, thanks to Rep. Duncan Hunter. It's been very effective and reduced illegal crossing from Tijuana by some 95%. It's why the illegals targeted Cochise County down by Tombstone, Arizona that barely has a barbwire fence in place for cattle. Also, the very reason the Minutemen (I was a member) formed. Google San Diego double fence.
I don't get it, unless it is deteriorating so much and needs repair. However, there are sections east of Otay Mesa that could use an effective barrier to the Yuma area border.

That’s where Border patrol said they needed it. I think they want bollards because they are tied of whack-a-mole, with frequent cutting of breaches, and having to find and repair them.
Trump is targeting the highest traffic areas first - basically the urbanized areas of the border. Cochise County would not get their barrier for several years, at the Congressionally envisioned rate of $1.6 per year (~100 miles urban, 150 rural). If a big enough lump of funding comes through in the next budget (October, if no continuing resolutions), Cochise County could get contracts awarded next year, with about 1-2 years to build.
