Mike speculates at the end of http://www.vahighways.com/scannex/route-log/sc002.htm that SC 2 may have had the largest reduction in length. At its peak, it was about 288 miles, while it's now 3.9, only 1.4% of its former glory.

VA 13 went from about 193 to 24, which is 12%.

TX 1 doesn't count; in 1939 it appears to have remained, but it was actually renumbered from the short 1B.

Can anyone think of others that might qualify? It has to have been the same route from beginning to end (with a potential wholesale renumbering thrown in there, such as if the number conflicted with an Interstate).

My first thought was U.S. Route 91.

AZ 73 came to mind for some reason, the current route is only about 47 miles long whereas the original alignment ran from Eager through the San Carlos Reservation to US 180 (i). AZ 73 actually even carried US 60T when the alignment through Salt River Canyon was being built and it can be seen on the 1935 state highway map:

Today its hard even to find any old alignments of AZ 73 on Google Maps. 

Not sure if this is what you mean, but for Minnesota, MN-100 used to form a ~60-70 mile circle around the Twin Cities. Today it remains as a 16-mile freeway through a number of western suburbs.

The Hardy Toll Road, because it's signs are purple

Ontario Highway 2, formerly the main street of southern Ontario.  From 834.6km to 4.4km.

NJ 42 has been truncated and realigned to 14 miles where it was the entirety of the Black Horse Pike, from Camden to Atlantic City at something like 60 miles. Of course the road is mostly still there as NJ 168, US 322, and US 40, though 42 and 168 are no longer continuous as NJ 42 is routed onto the freeway and getting to 168 requires going on local streets.

Similarly, NJ 24 was moved to a 10-mile freeway (though it was planned to be longer), while pieces of the original 60 or so miles from Easton to Newark were re-designated as US 22, NJ 57, and NJ 124. But half of the route has been completely decommissioned and is maintained by the counties now.

California examples:

Route 24 used to connect Berkeley with US 395 near Reno at its furthest extent, but is now a mere 13 miles long between Oakland and Walnut Creek (with its most recent cutback occurring ca. 1991 when the Concord north-south freeway was finally signed as Route 242 officially).  Other portions of the route are now Route 70, Route 99, and Route 160.

Today's Route 71 is 15 miles long passing through the Chino area, but used to extend a mile or two further north (towards historic US 66) and significantly further south (originally in San Diego in the early 1930s, then after US 395 was commissioned, to Ribbonwood about 40 miles east of Temecula into the early 1970s)

Route 60 and Route 66 are severely truncated portions of what were once much longer US routes in the state.

Some others that come to mind would be 91, 17, and 178.  In the case of 178 I don't understand why 58 got the priority west of Bakersfield.

My guess:

Re: 178 - It's really interesting that the whole thing took after the pre-1964 LRN of 58 (along with the portion of US 466 that was covered by that legislative route number) when I'm not sure any other post-1964 route did that.  It certainly doesn't fit the semi-geographic number assignment of that time (i.e. 236, 237, 238 all replacing portions of another route that actually fits this thread, Route 9).

Cosigned with the still existing portion of Highway 49.

WIS 30, which used to go from Milwaukee to the Illinois border south of Platteville. US 61 and US 18 absorbed the western portion between the Illinois line and Madison and I-94 ate the portion from Madison to Milwaukee, leaving WIS 30 as a two-mile connector between 39/90 and downtown Madison today.

Ballpark guess is 180 miles, to 2 miles -> 1.1% of its original extent,

Well I think a lot of it had to do with SSR 178 being pulled north off of Pozo Road.  Really that actually made for a decent roadway with only the Old Salinas River Bridge as the only major hazard between Bakersfield and Santa Margarita.  Seems like the swap to 58 was more meant to emphasize they route as a "major" one.  The thing that I found odd about it is that 58 had to take a multiplex of 99 to get west of Bakersfield while 178 is a direct shot.  Really the Westside Parkway will actually make 58 align better west of Bakersfield but it certainly isn't a major state highway west to US 101.

IIRC there is one US route which, while still extant, doesn't keep any of its original routing.

Edit: It is US 601. Though much longer now, it originally ran from Florence to Cheraw SC along what is now US 52.

OK 14 was once nearly a border-to-border route, extending from Frederick in far SW Oklahoma to the Kansas line. Now, thanks to US highways taking over most of its route, it's only 27 miles long.

PA 60 only has ~ 10 miles left of it's full ~70 miles; after the Beaver Valley Expwy changed to I-376 (and the northern piece changed to PA 760).

The two PA 29s were once connected as well, before the middle piece changed to US then PA 309 - though there is some re-routing in Luzerne County.

Maryland Route 3 was once continuous from Baltimore to Cobb Island in Charles County, then U.S. 301 and the Nice Bridge arrived and Route 3 was reduced to the Cobb Island stub, giving it its first emasculation. Then the Cobb Island stub became Route 257 and MD-3, around the time of the 1952 opening of the Chesapeake Bay Bridge, was restored from U.S. Route 50 at Bowie to southwest Baltimore city. And then came Interstate 97 between Baltimore and Annapolis. It replaced Route 3 from Millersville on, leaving only the Crofton segment. A bizarre survivor through this was MD-3 Business through Glen Burnie.

When originally defined in 1932, Oregon Route 11 traversed the entire state of Oregon from the Washington border near Walla Walla to New Pine Creek at the California border, spanning around 400 miles. Then US-395 was extended down to San Diego in 1935 along most of its corridor. Today, it's about 34 miles long, more than a 90% reduction. Oregon Route 201 had a similar, though shorter, reduction when US-95 was extended along most of its would-be corridor around 1940.

One that should be emasculated: MA 128

VA 162?

M-17.  It used to cross the state as one of Michigan's original routes; now it just goes between Ann Arbor and Ypsilanti.

Since the original routes were numbered starting at 10 starting with the longest routes, many of the low-numbered originals were replaced by US routes.  That's what happened with most of M-17 - it became part of US-12.  But some of it east of Ann Arbor continued toward Detroit as US-12 followed Michigan Ave instead.  And most of that remnant was truncated back in later years.

US-223 in Ohio used to run off of US-23 at Monroe St. (Current SR-51) all the way into downtown Toledo, then head Northeast on Summit St. (Current SR-65) to I-280 at the Craig Bridge.

Today it's just a short mile-long multiplex with US-23 from Monroe St. Up to the Michigan Line.

For a state route in Illinois:  Probably either IL 5 (mostly replaced by I-88) or IL 7 (east end truncated and a good amount replaced by US 6).  See http://www.n9jig.com/1-20.html (http://www.n9jig.com/1-20.html).

Kentucky's entry into this category would probably be KY 35. Prior to 1950, it ran from US 42 at Warsaw to the Tennessee state line south of Albany. When US 127 made its entry into Kentucky, it took over all of KY 35's route from the current intersection of the two routes south. Now all that's left of KY 35 runs between US 127 and US 42, intersecting I-71 and passing by Kentucky Speedway.

For West Virginia, I'd nominate WV 4. At one time it ran from the Kentucky state line at Kenova to the Virginia state line between Romney and Winchester. Much of it was concurrent with other routes, including US 60 from the Kentucky line to Charleston and US 50 in that aforementioned stretch. Now it's primarily a standalone route from Clendenin (US 119) to south of Buckhannon (WV 20).

US-50 used to take a turn for US/CA-99 then take I-205, I-580 and I-80 to get the North San Joaquin Valley route to San Francisco. That was US-50 was realigned with I-305 in Sacramento to connect to I-80 and ended at the I-80 interchange in West Sacramento, CA. Its another emasculated route.

Not sure if this is what you mean, but for Minnesota, MN-100 used to form a ~60-70 mile circle around the Twin Cities. Today it remains as a 16-mile freeway through a number of western suburbs.

Adding MN 101 (excluding the two Chanhassen sections): 6 miles remain of 46, 13% of the original route.

It's still about 100 miles long, but MN 56 is now about 1/3 its maxlmum length.

The top 3 that I know of in Connecticut:
CT 101: was 91.8 miles in CT (1932-1935), now 9.46 (-90%, -82.3 miles)
CT 14: was 87.8 miles in CT (1932-1941), now 24.3 (-72%, -63.5 miles)
CT 27: was 9.84 miles, now 3.21 (-66%)

Going the other way is CT 201:
Originally 2.19 miles in 1934, it grew to 20.1 miles in 1963 (917% its original size). I'll leave it to you guys what term to use for that :-)

Yeah, I remembered MN-101 after I posted. :-D It's definitely up there as well. And MN-56 is a good addition too – I completely forgot about that one.

A grower would be something like Florida SR 200.. most of it hidden under the folds of US 301.. but over 200 miles when full accounted for

Z981

Historically, the longest route in CA to be truncated -- by the usual circumstance, commissioning of a US highway along the route -- would be the old SSR 7.  Its original length encompassed what was the 1950's-era full length of SSR (later CA) 107 (aka LRN 164) from the junction of Hawthorne Blvd. and Pacific Coast Highway in south Torrance, then segueing onto Sepulveda Blvd. (LRN 158) north through West Los Angeles and into the San Fernando Valley; multiplexing with SSR 118 (LRN 9) through San Fernando itself, then turning northwest onto Foothill Blvd. (LRN 157), which eventually merged into Sierra Highway (LRN 23), which it followed north on present CA 14 and US 395 to the Nevada state line (the last couple of miles north of SSR 89 were LRN 95).  SSR 7 reappeared near Hallelujah Junction NW of Reno, coming in on LRN 29 from the state line to LRN 73 at Johnstonville, and then following that route NE and north to the Oregon state line north of Alturas.  Of course, the entire route north of Inyokern is now US 395, with the portion from Sylmar to Inyokern (via Palmdale and Mojave) now CA 14.  The US 395 commissioning occurred ca. 1935; US 6 taking over the now-CA 14 segment occurred three years later.  And SSR 7 itself was rerouted at its southern end when LAX was expanded during and after WWII; instead of detouring through Inglewood and down Hawthorne Blvd.. Sepulveda Blvd. was extended south through Westchester, with Alternate US 101 (LRN 60) intersecting it at a 5-way intersection at Sepulveda and Imperial Highway, just south of LAX; this became the southern terminus of SSR 7 from 1945 to 1959, when LAX runways were lengthened to accommodate the 707's and DC-8's of the era.  That's when the cut-and-cover airport tunnels were constructed, and LRN 60/US 101A was rerouted through the tunnels, cutting off westward a few blocks north of Century Blvd., which was reconfigured as the main airport entrance.  SSR 7 was cut back to that point -- but only lasted another 5 years, as the system renumbering replaced it with I-405.  The number "7" was transplanted as new CA 7 to the Long Beach Freeway, replacing SSR 15, deleted because of I-15; but it too disappeared 20 years later when I-710 was commissioned over that facility.  CA 7 is now a short truck-crossing connector from I-8 to the Mexican border east of Calexico in rural Imperial County (my, how the mighty have fallen!).

I typed that utterly backwards, but upon rereading it it makes no sense either way. Oh well. It was early morning and I should know better than to post before I'm fully alert and awake!

Probably the best two cases from Indiana would be SR 29 and SR 43.

State Road 29 once went from Madison along the Ohio River up to Michigan City on Lake Michigan along the old Michigan Road. It got severily truncated due to US 421 and US 35 being introduced and now consists solely of a 30-mile stretch from Boyleston to Logansport in North central Indiana. This is why SR 129 and SR 229 are located in Ripley County, far away from the current SR 29, at one time they were much closer to the parent route.

State Road 43 once traveled from Solsberry in Greene County north all the way to Michigan City. Over time it was truncated by the addition of US 231 and US 421 to two small stretches in eastern Greene County and from Lafayette to Reynolds, totally 40 miles total. Even in the past few years the northern stretch was truncated even more from Downtown Lafayette up to I-65.

QC-155 and QC-161 seems to fit that category. When the gap of A-55 opened. QC-155 in the South Shore of the St-Lawrence River was decommisioned while the end of PQ-161 who was once at St-Celestin is now at TCH-20.

The only Nebraska highway that really fits is NE 63. It used to encompass the segment of NE 66 that goes west through Ashland over to US 77.

The only serious route truncation I can recall in Georgia was ~1993 when GA 13 north of Gainesville was superseded by GA 365. That chopped the route in half, dropping it from 99 miles to 49.

EDIT:
Wait, no, I can do much better. GA 50 used to be a cross-state route, from Eufaula, AL all the way to Jekyll Island along US 82 and US 84. Then GA 520 came along, cutting GA 50 all the way back to Dawson. From 244 miles down to 46.

It's so that it's not a single-state route. When the US routes were created, there were some guidelines on their creation, e.g. "must be fairly direct" and "must be 300+ miles or cross a state line".

Before the freeways, US-223 entered Ohio further west, on a separate road from US-23, near Sylvania.  US-23 was a ways to the east, going south from Ypsilanti through Ida and Temperance, entering Ohio nearly due north of downtown Toledo.

After the US-23 freeway was built, some of US-223 still was on surface streets in Sylvania.  Ohio and Michigan petitioned AASHTO to move US-223 to its current configuration in 1977.  Why they didn't truncate US-223 to the intersection with US-23 at that time is the question.

US-223 in Ohio used to run off of US-23 at Monroe St. (Current SR-51) all the way into downtown Toledo, then head Northeast on Summit St. (Current SR-65) to I-280 at the Craig Bridge.

Today it's just a short mile-long multiplex with US-23 from Monroe St. Up to the Michigan Line.

What is the point of US 223 in Ohio as it currently exists?

I guess as long as Michigan co-signs US-223 with US-23, Ohio has to recognize it to the first available exit, which is about 1-1/2 miles inside the border.  It would have made a little more sense if they actually extended the 23/223 multiplex a few miles down to the I-475 split when they took US-223 off of Monroe St.

I just drove the US 23/223 multiplex, it appears to just suddenly end on the US 23 freeway immediately entering Ohio.  The signage northbound just suddenly appears right before the Michigan state line without any warning. 

AsphaltPlanet beat me to Highway 2, which is the best example in Ontario, but there's some other Ontario ones worthy of mentioning. Three examples include:

Highway 20 - From 63.9 km to 1.9 km
Highway 5 - From 114 km to 12.6 km
Highway 24 - From >250 km to 74.5 km

The only serious route truncation I can recall in Georgia was ~1993 when GA 13 north of Gainesville was superseded by GA 365. That chopped the route in half, dropping it from 99 miles to 49.

EDIT:
Wait, no, I can do much better. GA 50 used to be a cross-state route, from Eufaula, AL all the way to Jekyll Island along US 82 and US 84. Then GA 520 came along, cutting GA 50 all the way back to Dawson. From 244 miles down to 46.

GA 55 also got a fairly large chunk truncated by GA 520.

Iowa highway 965 formerly ran 18 miles between Coralville and Cedar Rapids along the old alignment of US 218. In 2003, it was truncated to just under a half mile between US 6 and I-80. The DOT-maintained section is unsigned, but street blades in the old section still refer to it as "HWY 965"

AR 81: now the world (in)famous US 425: 88.5 miles. The only part left is a 2.29 mile route linking US 65 with US 63/US 79 around a papermill.

AR 15: most of it became the world (in)famous US 63 from US 167 in El Dorado to Pine Bluff: about 89 miles. Still exists in Union County from the LA state line to US 82, 21.1 miles.

CA-17 is an emasculated route. CA-17 in the Bay Area used to go as far north as the Richmond/San Rafael bridge to Santa Cruz, CA.

But the northern CA-17 became I-880 in the 1980's from Oakland to San Jose.

The Richmond/San Rafael bridge became I-580 in the 1990's though.

I-495 in Maine is a good example. It used to run for just over 50 miles on the Maine Turnpike between Falmouth and Gardiner, where I-95 followed the Falmouth Spur and up what is now I-295 north of there through Freeport and Brunswick. In January 2004, I-95 was rerouted on the Turnpike through Auburn/Lewiston and I-295 was extended north to Gardiner, moving I-495 onto the 3.7 mile Falmouth Spur (leaving it unsigned to boot).

More California examples:

Route 72 (former US 101) in Whittier is now a mere 7.1 miles long, as opposed to its heyday from 1964-1981 where it covered 26 miles from east Los Angeles to Anaheim.

Today's Route 150 covers a 36 mile loop from Santa Paula west to Carpinteria, but used to continue along a whole 68 miles west to Surf via today's Route 192, Route 154, and Route 246.

I'm surprised no one has mentioned US 80.  In its day, extending from the Atlantic in Georgia to the Pacific at San Diego, now stopping short in Dallas.

That's close to half, which is nothing near a reduction like the others mentioned in this thread.

US 666.  Not only was it orphaned (with the decommissioning of its parent, US 66) and trimmed, it was forced to take a whole new number.

AR 47 in Benton County, AR. Originally ran from Walnut & 8th St in Rogers to Mo 37 at the Missouri State Line.  Approx 18 miles

Later replaced by and truncated to US 62 at Gateway and extending just over half a mile to Missouri 37. Later renumbered AR 37.


There is an AR 37 in Jackson County, Arkansas which is not part of the Benton County route

The big one I can think of in Michigan is M-78, which only runs from M-66 north of Battle Creek to I-69 near Olivet currently. It used to run from the Indiana line near Sturgis to as far as Davison on its east end. This road was mostly replaced by M-66 and I-69.

Other examples in MI (but not to the extent of M-78) are M-17, M-21, M-29, M-35, M-42, and M-47. M-69 would have counted before its re-extension along its former route in around 2000.

In this side of the pond: the Spanish N-152 (no, Catalonia is and will be Spain). It used to run from Barcelona all the way to the French border at Puigcerda. Now all what remains of it is the last mile before France, the rest having either been delegated to Catalonia (which renumbered it to C-17) or renumbered as part of N-260.

US 10 was really slashed in length.

Don't get controversial!

AR 3. It used to begin at the Louisiana line south of Magnolia where AR 19 begins today and ended at AR 16 (today's US 64) near Crawfordsville. Most of it was replaced with US 79 except for the part south of Magnolia and the part from US 70 at Lehi north to US 64. It went from being about 275 miles long to being 18 miles long at the southern stretch and 5 miles on the northern stretch. The stretch south of Magnolia is now AR 19 and the stretch north of Lehi is now AR 147. AR 3 no longer exists.

Several single digit Arkansas state highways have been decommissioned. Here's a rundown:

AR 1: still exists
AR 2: no longer exists, largely replaced by US 82
AR 3: no longer exists, largely replaced by US 79
AR 4: still exists in extreme western and extreme eastern Arkansas, largely replaced by US 278
AR 5: still exists in several unrelated segments
AR 6: no longer exists, replaced by US 270. A later short lived stretch of AR 6 was replaced by US 49
AR 7: still exists
AR 8: still exists
AR 9: still exists

Maybe in the grand scheme of things, but it's still not nearly as much as some of the others here.

AR 4 is another good example. Until US 278 was extended west from Mississippi to Arkansas in 1998, AR 4 ran from the Oklahoma line west of Cove to AR 1 northeast of McGehee, a distance of approximately 260 miles.  The vast majority of AR 4 was decommissioned soon afterward and now the western section is about 3 miles long while the eastern section is about 22 miles long.

I'm surprised no one has mentioned US 21 yet.

Actually, US 10 is one of the largest cuts. It used to be about 2000 miles long, but it's now only 565.

This thread is about largest percentage cut. US 10 and US 21 are not even close to some others mentioned here in terms of percentages.

California 24 used to go across the Sierras but now is just a tiny freeway in the Bay Area...even was truncated by a three mile 3d Interstate.  :no:

State Road 43 once traveled from Solsberry in Greene County north all the way to Michigan City. Over time it was truncated by the addition of US 231 and US 421 to two small stretches in eastern Greene County and from Lafayette to Reynolds, totally 40 miles total. Even in the past few years the northern stretch was truncated even more from Downtown Lafayette up to I-65.

I remember when SR 43 was decommissioned where it was concurrent with US 231.  It seemed silly to leave it in two pieces like it ended up being.

Indiana SR 53 got it even worse from US 231: originally it ran from US 12/US 20 in Gary south all the way to US 52, but then US 231 took over its southern 76 miles leaving current SR 53 only 14 miles in length.

MoDOT eliminated 88. It ran from the AR-MO line to Lanagan, MO (replaced by US 71), then later used along Scenic Ave in Springfield, MO.

Also MO 44 and MO 57 were eliminated.

I'd nominate US 99 and US 10 but they aren't nearly as much as others on this list.

Historically, the longest route in CA to be truncated -- by the usual circumstance, commissioning of a US highway along the route -- would be the old SSR 7.  Its original length encompassed what was the 1950's-era full length of SSR (later CA) 107 (aka LRN 164) from the junction of Hawthorne Blvd. and Pacific Coast Highway in south Torrance, then segueing onto Sepulveda Blvd. (LRN 158) north through West Los Angeles and into the San Fernando Valley; multiplexing with SSR 118 (LRN 9) through San Fernando itself, then turning northwest onto Foothill Blvd. (LRN 157), which eventually merged into Sierra Highway (LRN 23), which it followed north on present CA 14 and US 395 to the Nevada state line (the last couple of miles north of SSR 89 were LRN 95).  SSR 7 reappeared near Hallelujah Junction NW of Reno, coming in on LRN 29 from the state line to LRN 73 at Johnstonville, and then following that route NE and north to the Oregon state line north of Alturas.  Of course, the entire route north of Inyokern is now US 395, with the portion from Sylmar to Inyokern (via Palmdale and Mojave) now CA 14.  The US 395 commissioning occurred ca. 1935; US 6 taking over the now-CA 14 segment occurred three years later.  And SSR 7 itself was rerouted at its southern end when LAX was expanded during and after WWII; instead of detouring through Inglewood and down Hawthorne Blvd.. Sepulveda Blvd. was extended south through Westchester, with Alternate US 101 (LRN 60) intersecting it at a 5-way intersection at Sepulveda and Imperial Highway, just south of LAX; this became the southern terminus of SSR 7 from 1945 to 1959, when LAX runways were lengthened to accommodate the 707's and DC-8's of the era.  That's when the cut-and-cover airport tunnels were constructed, and LRN 60/US 101A was rerouted through the tunnels, cutting off westward a few blocks north of Century Blvd., which was reconfigured as the main airport entrance.  SSR 7 was cut back to that point -- but only lasted another 5 years, as the system renumbering replaced it with I-405.  The number "7" was transplanted as new CA 7 to the Long Beach Freeway, replacing SSR 15, deleted because of I-15; but it too disappeared 20 years later when I-710 was commissioned over that facility.  CA 7 is now a short truck-crossing connector from I-8 to the Mexican border east of Calexico in rural Imperial County (my, how the mighty have fallen!).

Very true.  I associate low numbered routes as being more important.  I suppose the state had to renumber 7 and 11 as 710 and 110, but I never felt that as being necessary.   CA has many fine interstate quality state numbered freeways.

I wouldn't call the AR 5 segments unrelated. The concurrencies are just unsigned, as is typical of ARDOT.

Seriously though, if NY 17 is unsigned from I-86 when the latter is fully completed, it will be but a stub of its former self in western Rockland County.

Once you eliminate the future I-86 overlap, why not just renumber the Suffern-Central Valley stub as an extension of NY 32 and be done with the number?  NY 17 no longer directly connects to NJ 17 unless you enter the Thruway and Exit on I-287 and take the first exit.  Then, just renumber the 17 lettered routes to regular numbers.
