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

[dvferyance]

In Milwaukee Hwy 100 starts out on the northside as Lovers Lane briefly before changing to Mayfair Rd than later 108th but than later changes back to Lovers Lane. Also Hwy 181 is Wauwatosa Rd in Wauwatosa switched to 76th in Milwaukee than switches back to Wauwatosa Rd in Mequon. Anymore examples of this anyone else knows about? In the case though of Hwy 100 the whole thing was once called Lovers Lane so it wasn't always like that. Wauwatosa changed there portion to Mayfair Rd while West Allis and Greenfield changed theirs to 108th. Milwaukee and Franklin kept their part Lovers Lane resulting in 2 short segments of it an each end.

Gratiot Ave in Mt. Clemens MI changes to Main Street before changing back to Gratiot Ave. this is because it was the old route for Gratiot Ave in the city (before the newer northbound and Southbound routes was built in the 60s)

[Flint1979]

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.

Crawford Avenue/Pulaski Road in Metro Chicago.  In the north suburbs, it's Crawford, then in the city, it's Pulaski, then back to Crawford in the south suburbs.

US 3 in MA between exits 33 and 34: Dunstable Rd. turns into Makepeace Rd. just to cross US 3, and then it changes back to Dunstable Rd. I initially thought that it was because overpass names are shown on freeways, but this one is an underpass.

Good thread!

This section (partially NY 286 and partially unnumbered) is Browncroft Blvd, but it turns back into Atlantic Ave. in both directions. Basically, the four-lane section gets the honor of being called a "boulevard", while the majority of the route, including urban, suburban, and rural sections, is just two lanes, and is therefore an "avenue".

This is pretty common in incorporated cities and towns. I know of two examples in my general area:

• On Maryland's Eastern Shore, Maryland Route 213 (MD-213) changes from Washington Avenue to Augustine Herman Highway when it leaves Chestertown in Kent County. In Galena, about 15 miles to the northeast, it becomes Main Street, and intersects MD-313 and MD-290. MD-213 then leaves Galena and becomes Augustine Herman Highway again, carrying that name to U.S. 40 (Pulaski Highway) just shy of Elkton city limits in Cecil County.
• In northern Harford County, Maryland, Fawn Grove Road stems from MD-165, and becomes Market Street when it crosses the Mason-Dixon Line into a Pennsylvania and into the same-name borough Fawn Grove. After leaving Fawn Grove and splitting from PA-425, it becomes Fawn Grove Road again.

Referring to the Berlin Turnpike (US 5/CT 15) in central and south-central Connecticut:

It runs from Meriden north-northeast to Wethersfield. The road always had that name in Meriden, Newington and Wethersfield. However, the town of Berlin itself used to sign it as the Wilbur Cross Highway. Thing is, that's what CT Route 15 is known as once south of the Berlin Turnpike (where US Route 5 splits off and becomes Broad Street locally in Meriden).

Going northbound: Livernois in Detroit, Ferndale and Pleasant Ridge changes (with a discontinuity) to Main St in Royal Oak and Clawson, then back to Livernois in Troy.

[US 89]

Heading north on Utah 126 through Davis County, you'll start out on Main Street in Layton. It changes to State Street at the Clearfield city limits to avoid confusion with that city's Main Street, but then 126 itself veers onto the alignment of the Clearfield Main Street and the name changes accordingly.

Utah 68 is almost universally known as Redwood Road in Salt Lake and Utah Counties, but the name briefly changes to Camp Williams Road within Bluffdale and Herriman city limits. This is well documented on city-installed street blades, but the UDOT signage at traffic signals just calls the whole thing Redwood. The Salt Lake County streets database has Camp Williams Road as the official name of this segment, though Redwood Road is listed as an acceptable alias.

In Philadelphia, both 5th & 6th Streets near Independence Hall become Independence Mall East & West respectively between Market & Chestnut Streets.

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.

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.

12th Street in Oakland merges into Lake Merritt Boulevard, and then reappears at 1st Avenue.  With the 90s renaming of much of East 14th Street to International Boulevard, 14th essentially feeds into Lake Merritt Boulevard and then reappears miles down the road in San Leandro along Route 185, with East 14th being the only numbered street in that area!

A little bit of a technicality for this one: the old Bayshore Highway routing through San Francisco International Airport was subsumed by runway expansion decades ago, so the San Francisco-Brisbane segment of Bayshore Boulevard and the Millbrae-Burlingame segment of Old Bayshore Highway is connected by Airport Boulevard and South Airport Boulevard (former US 101/bypass US 101) from South San Francisco to San Bruno, then the airport frontage road McDonnell Road between San Bruno Avenue and Millbrae.

US 3 in MA between exits 33 and 34: Dunstable Rd. turns into Makepeace Rd. just to cross US 3, and then it changes back to Dunstable Rd. I initially thought that it was because overpass names are shown on freeways, but this one is an underpass.

It goes from Tyngsboro (as Dunstable Rd) into Westford (as Makepeace Rd) then back into Tyngsboro to regain its name. From North Chelmsford, you actually go Chelmsford/Tyngsboro/Chelmsford/Tyngsboro/Westford/Tyngsboro in less than a mile, with two of those borders signed.

This is reasonably common in Virginia when roads pass through independent cities or towns.

One of the more interesting ones is VA-123. Heading north, it becomes Chain Bridge Road near Fairfax City. It changes to Maple Avenue through the Town of Vienna, then becomes Chain Bridge Road again. Then it becomes Dolley Madison Boulevard for a while (without crossing a jurisdictional border) before becoming Chain Bridge Road again to its terminus.

US-29 is another. It's Lee Highway in Arlington, then it briefly becomes Old Dominion Drive. Old Dominion splits off as VA-309 and US-29 becomes Lee Highway again, then becomes Washington Street through the City of Falls Church, then becomes Lee Highway again when it enters Fairfax County.

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.

If suffixes don't count, the old US 60/70/80/89 is called Apache twice.  Once in Tempe (Apache Blvd.) between Mill Ave. and the Mesa city limits, and again (Apache Trail) between Power Rd. in Mesa and AZ 88 in Apache Junction, which then picks up the name on the northeast (original) leg to Roosevelt Lake.  In between (most of Mesa), it's called Main St.

[WNYroadgeek]

NY 265 is Military Rd twice, from Amherst St. in Buffalo to the Tonawanda city/town line, then again from Cayuga Dr. in Niagara Falls to NY 104 in Lewiston.

US 20A is Big Tree Rd three times, from US 20 in Hamburg to Thorn Ave. in Orchard Park, from NY 400 in East Aurora to NY 77 in Sheldon, and from NY 256 in Lakeville to West Ave. in Livonia.

The main north-south street in Lemont, IL is known as State Street in town, but north and south of town, it's labeled as Lemont Road.

[TheGrassGuy]

Technically this is more like a road multiplexing with another than a true example, but in Morris County, NJ, from Mountain Lakes to Kinnelon:

Powerville Rd -> Boulevard -> Elcock Ave -> Powerville Rd -> Kinnelon Rd -> Kiel Ave

[frankenroad]

Ross Avenue in St Bernard, OH, becomes Tennessee Ave when it crosses into the city of Cincinnati, and then back to Ross when it crosses into the city of Norwood.  Each of the three segments is less than a mile long.

I feel like there are others in the Cincinnati area, but I can't think of them at the moment.

[Finrod]

In northeast suburban Atlanta, SR 141 is Peachtree Parkway where it splits from Peachtree Industrial Boulevard, which turns into Medlock Bridge Road when it crosses into the next county, then turns back into Peachtree Parkway when it crosses into the county after that.

[Konza]

The main north-south street in Lemont, IL is known as State Street in town, but north and south of town, it's labeled as Lemont Road.

I suspect there are a number of these in the Chicago suburbs, Lake Cook Road through Barrington being one of them.

[jay8g]

Seattle has a few examples of this because nothing about our street grid makes sense, but the most interesting is Lake Washington Blvd S and Lakeside Ave S. The road along Lake Washington in the central part of Seattle is mostly Lake Washington Blvd, but a small section is Lakeside Ave S because the boulevard turns off and runs along the top of the bluff for a couple miles. The reason for the street name turning off like that is that LWB is a historic Olmsted boulevard, while Lakeside Ave S is presumably a later addition.

[skluth]

Lindbergh Boulevard as it circumnavigates St Louis changes its name to Kirkwood Rd in Kirkwood and the generic Hwy 67 in north STL County.

[woodpusher]

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."

[GaryV]

Extremely expensive property.  People like the Ford family live there.

And not just the cachet of a "fancy" road name - it also differentiates that "We are no longer in Detroit."
