The Future of the U.S. Numbered Highway System

I'll just leave it with this: Texas has been known to take corridor definitions very, very narrowly (see: I-69E/C/W).

I'll just leave it with this: Texas has been known to take corridor definitions very, very narrowly (see: I-69E/C/W).

Just for the sake of designation -- and keeping the funding stream open as wide as possible.  To that end, they (probably wisely) elected to not overestimate the intelligence and capability for rational thinking of their pet congresspeople -- particularly those who were part of the original corridor concept back in the early/mid 1990's.  As far as actual in-the-field routing goes, it'll be up to the planners & engineers, who tend to "straightline" routing oddities for the sake of monetary outlay as much as anything (hence bridging the Brazos at its narrowest point). 

This should have been saved for the I-14 thread -- but please take note that US 190 itself between I-35 and I-45 was an overlay of a series of state or other US highways (TX 36, US 79, TX 6, TX 21); there's not a bit of 190 there that isn't MPX'd with other field-signed routes.  A real grid-pattern anomaly!

Well, considering US 190 originally stopped at the Mississippi River, seeing it mpx'd with other routes doesn't shock me.
