This isn’t an Iowa story, obviously, but it’s important for the interstate system as a whole. The Nevada DOT is replacing Interstate 515, which ran southeast from Las Vegas toward the Hoover Dam area, with Interstate 11. The I-11 designation starts at the Arizona-Nevada border with the bridge that was built to bypass Hoover Dam and for a while has ended at the I-215/I-515 interchange. Now it will go through to the northwest end of the Las Vegas sprawl.
Beyond that, future plans would take I-11 up the US 95 corridor somehow, past a WHOLE LOT of nothing, to the Reno area. The news story says the Nevada DOT says “Canada to Mexico” but getting to Reno alone is a pipe dream. Did you know there are only three highways, total, that cross between Nevada and Oregon?
(Notice that the Las Vegas newscasters use the “the” terminology for freeways one typically experiences only in the Los Angeles area.)
