Inefficient numbered routings

[hbelkins]

Has anyone brought up US62 between Paducah, KY, and Cairo, IL?  US62 dives down south and comes back north, whereas KY-286 joins the two bookending segments far more efficiently.

You can throw US 60 into that mix as well.

MA 9 through Amherst; it would be much geographically shorter to bypass the town along Bay Rd.

Also, QC 141 north of Magog; it takes a long loop for no particular reason; it would be much more logical to end it at the intersection with Main St/ Rue Principale (QC 112) at the center of town.

MN 25, which awkwardly zig-zags its way from Belle Plaine to Brainerd. It's basically a 155-mile long local traffic route except for the Buffalo-Big Lake section. The most inefficient parts can't really be turned back or realigned either because of constitutional route requirements.

Smethport PA to Warren PA (Western PA), US-6 goes through both but looking at a map it seems like PA-59 was either the original routing or was built later to shave some miles off.

MA 80, which shouldn't even exist. It makes a loop around nothing. At least I can understand why MA 145 exists.

That is such a pointless route. It also gets an easy number for no reason.

I believe US 6 was routed that way to serve the more developed areas of Mt. Jewett and Kane.  In fact, when the US highway system was first laid out, US 6 (along with US 219) ended in Kane.  US 120 went the rest of the way to Erie (along modern US 6 and US 6N). [Wikipedia]

It's true that PA 59 is a "northerly bypass" of US 6.  However, as inefficient as it may seem, US 6 and PA 59 are not going to be swapped.
