Roads that change names but then latter change back to the previous name.

Near LAX, Route 1 follows Sepulveda Boulevard underneath the airport runways, which then (due to a recent local decree) becomes Pacific Coast Highway in El Segundo.  In Redondo Beach, the Sepulveda name reappears until Artesia Boulevard/(former, but still somewhat signed?) Route 91.

And south of Artesia, it is PCH again, so the continuous route is:

Sepulveda -> PCH -> Sepulveda -> PCH

Sepulveda then pops up one more time for its final southeast segment at the south edge of Redondo Beach, before heading east to Route 103 in Torrance where it becomes Willow Street.

This iteration of Sepulveda has no direct connection to the other route, though. It seems like it was planned to connect via Camino Real (which itself has had a sorta-disconnect at Torrance Blvd), but Camino Real was stopped short one block from Sepulveda/PCH. Several sources (including Wikipedia, but also quasi-reference books like "Los Angeles A to Z") list Sepulveda as the longest street in L.A. County, but it really is at least two totally separate roadways that just share a name.

Meanwhile, close but not quite: the former CA-9 (then CA-85) between Saratoga and Sunnyvale is called (surprisingly) Saratoga-Sunnyvale Road, then changes to De Anza Boulevard at the Cupertino city limits, then to Sunnyvale-Saratoga Road at the Sunnvyale city limits. It was originally all Saratoga-Sunnyvale Road, but when the De Anza section was renamed, Sunnyvale switched the city order on the name of their section.

In Oklahoma City, several east west streets change names at the Moore/Oklahoma City line on the west side, then change back at the eastern boundary between the cities:

–SW 104th becomes North 27th Street while in Moore
–SW 119th becomes North 12th
–SW 134th becomes South 4th
–SW 149th becomes South 19th
–SW 164th becomes South 34th

Seattle has a few examples of this because nothing about our street grid makes sense [...]

There's also a few notable grid-related examples in the rest of King County as a result of the County's efforts to prioritize numbered streets over named streets. There are a few roads with straight sections lining up with the grid that are numbered, with winding and/or diagonal sections around them, leading to the road flipping from a name to a number and back.

Notable examples include Northup Way -> NE 20th St -> Northup Way in Bellevue and SE Kent-Kangley Rd -> SE 272nd St -> SE Kent-Kangley road near Covington and Maple Valley

In West-Central OH, State Route 48 is known as (N or S) Main St. for most of its route north of and through the city of Dayton.  But when it goes through Oakwood and Kettering, it's known as Far Hills Ave (it's clearly a "main" street in Oakwood; Kettering maybe not as it sprawls mostly to the east.)  South of there, in Centerville, it's back to Main St.

Further west, Union Rd. maintains that name for its length, except when it runs through Trotwood where it's known as Broadway.

One I encountered recently in South San Francisco:

Spruce Avenue -> one block named "School Street" past an elementary school -> North Spruce Avenue

Always thought this was extraordinarily superfluous given how short the School Street segment is.

One could argue that SF does something similar with the segment of Polk Street in front of City Hall, which is officially Dr. Carlton B. Goodlett Place now.

Also in the Detroit area Jefferson Avenue changes to Lake Shore Drive for the Grosse Pointes and then changes back to Jefferson Avenue at the Wayne/Macomb County line.

Is it expensive property?

I recall remarking, "It doesn't matter if you're in New Orleans, Baton Rouge, or Chicago:  Lakeshore Drive means expensive property."

The Grosse Pointes are among the most wealthiest of places in the Detroit area so yes it is pretty expensive. The Edsel and Eleoner Ford House is on the street. It's in Grosse Pointe Shores which is probably the most wealthiest of the Pointes.

In Kenosha, WI, Highway 32 is Sheridan Road.  On the north side of town there is an intersection where if you follow Highway 32 by going straight the road becomes Alford Park Drive and if you keep going north it becomes Sheridan Road again when you are north of Carthage College.  I'm not sure if this one counts because at that same intersection you could turn left to follow Sheridan Road which then connects again with Sheridan Road north of Carthage College.

In Kenosha County, WI, Highway 142 west of I-94/I-41 is Burlington Road.  The road has a number of curves but generally goes WNW toward the city of Burlington; however, when the road crosses US45 it straightens out and goes directly west and that small straight portion is 15th Street which follows county grid scheme, then it curves again and goes back to being Burlington Road.  If you were to follow that road from the lakefront in Kenosha to where it ends in Burlington you would be on Washington Road/38th Street/Burlington Road/15th Street/Burlington Road/Bushnell Road/Main Street.

In downtown South Bend, Michigan Street veers to the east for five blocks and then veers back to the west. For many years that five-block section was called St. Joseph St., in accordance with non-contiguous sections to the south and north.  Recently, those five blocks were renamed Dr. Martin Luther King Jr. Blvd. The rest of old St. Joseph Street retains the old name.

Ohio State Route 120 turns into a county road (Morenci Road, Territorial Road) at the Michigan state line and eventually back to a highway when it reaches Indiana: State Road 120.  The Michigan section was formally M-120 on the route that connects Toledo & Elkhart.

You missed a bit in the middle.  Morenci Road changes to Main Street in the city of Morenci.

But the roads in IN and OH also have names in some places.  For example, it's Morenci Street in Lyons, OH.  And Territorial Road changes to Toledo Street (along with Indiana 120) after it crosses into IN.

So unless IN 120 is the same name as OH 120, the whole thing can't be considered as switching back to the same "name".

Not sure if this counts, yet I think it might:

In Koreatown in Los Angeles, Normandie Avenue splits into Irolo Street and Normandie Avenue at Olympic Boulevard.

The fork of Normandie ends at 7th Street, while Irolo eventually becomes Normandie again at Wilshire!

Further north, in the San Mateo/Foster City area, 3rd Avenue becomes J. Hart Clinton Drive east of Norfolk Street, then East 3rd Avenue once the road enters Foster City.  (This used to be the main approach road to the San Mateo Bridge until the 1960s)

One that may or may not count, and kinda similar to the Koreatown example above, is the various Almaden streets in San Jose:

https://www.google.com/maps/place/Willow+St+%26+S+Almaden+Ave,+San+Jose,+CA+95110/@37.3250432,-121.8948339,16.46z/data=!4m5!3m4!1s0x808e334bb421ed3b:0x1f9aca00dbbdbeea!8m2!3d37.3189317!4d-121.8822365

Southbound, one drives from Almaden Boulevard in downtown San Jose to Vine Street to Almaden Road.

Northbound the transition isn't quite there: Almaden Road to Almaden Avenue.

So unless IN 120 is the same name as OH 120, the whole thing can't be considered as switching back to the same "name".

In both Ohio and Indiana, the road is a state highway labeled "120." In between in Michigan, it is not a state highway labeled "120."  There ya go.

This is a bit out of hand: https://www.google.com/maps/place/Little+Rock,+AR/@34.7313278,-92.2407403,14.66z/data=!4m5!3m4!1s0x87d2a134a11f569b:0x3405f5100df35b17!8m2!3d34.7464809!4d-92.2895948

I originally read this as "Road name is changed by government.  People refuse new name.  Road name changed back."


However, most of these examples are caused by jurisdictional changes, and don't seem to be what OP was suggesting.


However, Seattle has a few that aren't.


1st Ave S, in front of T-Mobile Park is designated as "Dave Neihaus Way", and is no longer legally 1st Ave S.  However, 1st Ave S exists on either side of this 1-block stretch of roadway.


Similarly, due to roadway design changes, Royal Brougham Way (along the north side of T-Mobile Park), is elevated over the railroad tracks, then loops back down to 3rd Ave S.  There is then a 1/2 block disconnect where the primary traffic pattern is on 3rd Ave S, before turning back on to Royal Brougham Way.

I can think of lots of others that change names when passing through independent cities and towns but don't necessarily do so multiple times, or that used to do so before bypasses were built.

U.S. 1 in Virginia is another one.  For now, much of it is Jefferson Davis Highway, though I think that the name of the President of the Confederacy will be coming down in the years to come.

A long section of U.S. 1 in Arlington County and City of Alexandria was Jeff Davis Highway but is now Richmond Highway.  In Alexandria, the southbound side becomes Henry Street and the northbound side is Patrick Street.

In Fairfax County, U.S. 1 has been Richmond Highway for as long as I can remember.

In Prince William County, the Jefferson Davis Highway on U.S. name remains, though in the Town of Dumfries,  southbound is Main Street and northbound is Fraley Boulevard.

South of Dumfries, Jefferson Davis Highway resumes. 

I believe it is Jefferson Davis Highway across most of Stafford County, though it becomes Cambridge Street as it gets close to U.S. 17 Business and into the City of Fredericksburg but Jefferson Davis Highway resumes in the city.

In Spotsylvania County, the name Jefferson Davis Highway continues.

Same in Caroline County. 

Someplace around the North Anna River the road becomes  Washington Highway as it heads into Hanover County.

Crossing the Chickahominy River into Henrico County the name changes to Brook Road. 

I don't feel like heading further south right now.

Nashville has Harding Place running from Harding Road (US 70S) to Granny White Pike, then it turns into Battery Lane from there to Franklin Road (US 31), then becomes TN 255 and Harding Place again and goes all the way to Murfreesboro Road (US 41/70S) near BNA.

History plays a large part in this.  Battery Lane has always ran along its current route, and Harding Place originally only ran from Harding Road to Hillsboro Road.  It was extended east to meet Granny White Pike at Battery Lane in the 50's or 60's when my dad was growing up in that area, and in the 60's and 70's the other Harding Place running east of Franklin Road was constructed up to at least Antioch Pike, then in the early 80's it was extended through construction and renaming to finally meet up with Murfreesboro Road.  There are other realignments in that area but I won't go into those.

A lot of folks automatically assume that Battery Lane is Harding Place, but it really doesn't seem to cause too many problems other than general nitpicking.  It's a lot better situation than Old Hickory Blvd, that's for sure!

Milwaukee renames certain stretches of roads.  For example part of S 27th St is renamed Layton Blvd, then 27th St on either end.  (This one is confusing as there is a Layton Ave nearby but that is a subject for another thread.)

[Michael]

Between Marcellus and Syracuse, there's a portion of Howlett Hill Rd that becomes Dunbar Woods Rd.  It's pretty obvious that Dunbar Woods Rd was built as a bypass of the turn on the old Howlett Hill Rd.  My best guess is that they used a new name so people on the old Howlett Hill Rd wouldn't need to get new addresses.

US 11 in Syracuse has a weird double jog that I didn't notice until several years ago that kind of fits in this thread.  On the south side of Syracuse, it jogs from South Salina St to South State St.  On the north side of Syracuse, North State St meets North Salina St and US 11 turns onto North Salina St.  I'd understand the jog if Salina St had multiple sections or one-way portions, but it's a through street.

[Rothman]

Eh, US 11 is just routed around downtown Syracuse.  That's not the weird thing to me.

The signage is horrible at Wolf and Salina.  Try following US 11 southbound.

Orlando FL: SR 436 is known as Altamonte Dr in Altamonte Springs, but is known as Semoran Blvd on either side of that city

NY 32 does a similar jog in southern Albany, which is even stranger.  Unlike US 11, it's an obvious jog both times.

What about the US 9W "U-Turn" -- comes from the east, heads up Southern and then turns northwest up Delaware?  No GPS has ever had me follow that route.

That doesn't strike me as particularly strange.  Unlike NY 32, there is NO direct way to get from exit 23 to Delaware and Lark.  Most of the streets north of 2nd Ave are narrow one-ways.  One way or another, you'd have to have a route somewhat resembling what is there (unless you finished the Mid-Crosstown Arterial), and the route they have minimizes the number of turns.  Going a different way only really makes a ton of sense if coming from I-787, and I-787 wasn't planned to end there either.

[-- US 175 --]

The only one I know of off the top in north TX is:

Greenville Ave. (Dallas) => Greenville Ave. (Richardson) => Plano Rd. (Richardson) => Ave. K (Plano) => Greenville Ave. (Allen)

All of this was part of the pre-N. Central Expwy. routing of US 75.  Amazingly enough, only part of the Dallas route really could be considered the way to Greenville (the town NE of Dallas); the rest farther north, as well as the parts in Richardson and Allen, don't really point the way to Greenville in a directional/compass sense.

There are other streets/roads that change names (mostly at city/town borders, but not always) in the DFW area, but the Greenville Ave. example was the only one I could think of that does it like the OP's name-switches-back topic.

There is almost another, but Hillcrest (Dallas) transitions to Ohio Dr. (Plano) but there is no street transition point onto Hillcrest (Frisco), like there probably should have been.  Ohio goes on into Frisco from Plano separately from the point where Hillcrest starts again in Frisco.

[Rothman]

Take a look at what Google Maps makes you do if you're headed onto Delaware coming north on US 9W:
