What is the longest signed Alternate or bannered route?

[Avalanchez71]

Just curious as to what alternate numberd route out there is the longest in length?  I would also say that suffixed routes are also included in the count.  You could also advise by banner type as well, i.e., longest BUSINESS route, longest suffixed route, etc.

US 90A (Alternate) in Texas is 175 miles.

IIRC before the Hoover dam bypass opened to traffic there was a Truck US 93 that was far longer than all other truck routes. While most, if not all, truck routes don't go further than 10 miles, this one was around 100 miles long.

There is still a US 64 TRUCK in western NC that is about 80 miles long

Looks like we have a few long Alternate and Truck routes; I wonder what would be the longest Business route.  Business routes are never very long since they only exist to serve the cores of towns that get bypassed by the main route.  In some states they aren't even state-maintained but are locally-maintained instead.

Wasn't/isn't there an Alternate US 93 or 95 in Nevada that is pretty lengthy?

[jp the roadgeek]

Has to be FL A1A.  Almost 339 miles.

Correct!

Alternate US 95 (which serves to connect US 95 coming up from Vegas with I-80 heading out towards Reno) is 107 miles long from Schurz to near Toulon Lake, including a 38-mile concurrency with I-80.  (US 95 only takes 71 miles between the those two points)

The Lyman-Fort Bridger Wyoming loop is the longest I can think of, but that's only 15.5 miles. Surely there's a longer one.

Business I-70 through metro Denver is 26.8 miles long (from near Golden to east of Aurora).

Us 17 alternate in South Carolina is really long from near Walterboro to Georgetown, not sure of exact length but over 100 miles

It is about 125 miles.

US 321 Bus from Dallas NC to Hickory NC is about 40 miles.

[jlwm]

US 90 Alt in TX is about 175-180 miles long and runs between Seguin and Houston.

[CNGL-Leudimin]

Business I-70 through metro Denver is 26.8 miles long (from near Golden to east of Aurora).

Bus I-85 from Lexington to East of Greensboro is even longer at 43.5 miles (Interestingly, that amounts to exactly 70 km).

Even though it isn't full freeway the entire length, would that qualify as the business route (of any kind) with the longest combined freeway segments? (7.4 miles in Lexington, 9.3 miles from Urban Street in Thomasville to Durand Avenue in High Point and 15.6 miles from River Road in Jamestown to I-840/I-85 (including the brief hidden section along I-85 and the concurrency with I-40))

Denver's Business I-70 seems to be the longest business Interstate route that is entirely surface road.

[mariethefoxy]

MA 1A is 95 miles

MA 3A is 97 miles

[Avalanchez71]

What is the length of US 31E & US 31W?  They are split from Nashville, TN to Louisville, KY.  Interesting side note is that both cities are actually consolidated governments.

[roadman65]

US 27 alternate from Williston to Perry in FL is about 96 miles.  68 of them are concurrent with US 19 & 98, but nonetheless a straight through alternate.

[plain]

Even though it's not really an official bannered route, I've always considered FL A1A as sort of a US 1 ALT in Florida. Kinda special for some reason in my opinion...

[ET21]

ALT I-39 has some pretty long sections in both Illinois and Wisconsin, but there's some inconsistencies with signage or large gaps where no signage exists.

The only long route I know personally is IL-251

Business 76 from Ft Morgan to Sterling is fairly well signed except within the corporate limits of the city of Sterling. It maxes out at a distance of approx. 57 miles. See http://www.interstate-guide.com/business-routes/bus76.html and https://www.aaroads.com/west/bl-076_co.html for more.

BUSINESS US 287 in Ft Worth, Texas is 38.5 Mi

[Mapmikey]

Former I-95 Bus from Kenly to Gold Rock was 45 miles.

I-20 Bus for Odessa/Midland is 30.2 miles

US 14A in northern Wyoming is 103 miles long, including a massively steep incline into the Bighorn Mountains. It's also where you can find this doozy of a sign...
