I think there could be a lot of it built in the next 3.5 years. However, I don’t anticipate that it would all be done. Main big runs, sure, but tricky areas could get skipped while they figure out what to do with a tributary stream etc.
When big runs of miles of an impressive wall is ribbon cut, it makes for great television. Big beautiful or Big ugly depending on the network and the presentation. Theater!
I’m sure the media will give us a big ugly blow by blow...
