# Special routes of U.S. Route 41

Several special routes of U.S. Route 41 exist, including three in Wisconsin. In order from south to north they are as follows.

## Existing
### Fort Myers business loop

U.S. Route 41 Business is a former segment of U.S. Route 41 in Downtown Fort Myers and North Fort Myers, Florida. North of State Road 80, it carries the hidden designation State Road 739.
The road begins at the interchange of US 41 and SR State Road 80-82-867, historically known as the Five Points Interchange. The road briefly overlaps SR 80 along Main and Monroe Streets, where it becomes discontinuous (it once continued east along with SR 80 though downtown along the then-one-way First Street and Second Street but those streets were turned over to city control in 2006).
Business US 41 resumes along SR 739 at SR 80, where it runs along Park Avenue (northbound) and Fowler Street (southbound) until they reach the Edison Bridge where the two streets merge. After crossing over the Caloosahatchee River BUS 41 enters North Fort Myers where it briefly becomes a six-lane undivided highway only for the divider to return north of Cabanna Avenue. The road heads north, intersecting with State Road 78. Between State Road 78 and Powell Drive, the road becomes a four-lane divided highway for the remainder of the route. The road finally ends at a former wye at US 41.

### Venice business loop

U.S. Route 41 Business is a former segment of U.S. Route 41 and an existing segment of the Tamiami Trail in Venice, Florida that begins near Shamrock Boulevard in Venice Gardens and terminates at Venetia Bay Boulevard in the Eastgate section of Venice. The existing US 41 in Venice runs along the Venice Bypass (hidden SR 45A).
Major intersections The entire route is in Sarasota County.

### Bradenton business loop

U.S. Route 41 Business is an alternate route and former segment of U.S. Route 41 in Bradenton, Florida that begins at State Road 684 (Cortez Boulevard West) where it runs along 14th Street until it makes a sharp right turn onto 8th Avenue West and then makes another sharp left onto 9th Street West before intersecting with State Road 64 on eastbound 6th Avenue West and westbound Manatee Avenue West. The road continues north as it passes by South Florida Museum and Bradenton Riverwalk before crossing the Green Bridge and moving onto 8th Avenue W in Palmetto where it intersects 10th Street West, which leads to State Road 43 where the northern concurrency of U.S. Route 41 and U.S. Route 301. As 8th Avenue West passes by 21st Street West, it becomes Valencia Drive and curves to the northeast before terminating at an interchange with US 41 just south of the interchange between US 41 and US 19 in Memphis.
Major intersections The entire route is in Manatee County.

### Tampa business loop

U.S. Route 41 Business is an alternate route to U.S. Route 41 in Tampa, Florida that begins on the Nebraska Avenue-Florida Avenue apex in Lutz and continues south on Florida Avenue. Just south of Hillsborough Avenue (U.S. Route 92), Florida Avenue becomes a one-way street and the south-bound portion splits off into Highland Avenue and later Tampa Street until Downtown Tampa. The route joins State Road 60 at the one way couplet of Kennedy Boulevard (northbound) and Jackson Street (southbound). Jackson Street rejoins Kennedy Boulevard at Meridian Avenue in the Channelside District and the route continues east for 3 blocks until turning north on Channelside Drive. Shortly after, the route makes a slight curve east onto Adamo Drive until the two routes depart at 21st Street (southbound) and 22nd Street (northbound). The route continues south and 21st Street merges back with 22nd Street shortly before a parclo interchange with SR 618 (Selmon Expressway) and crosses over McKay Bay along the Licata Bridge. The route makes a slight curve and continues east as Causeway Boulevard until it reaches its southern terminus near Port Tampa Bay at US 41 (50th Street) and State Road 676 (Causeway Boulevard).
U.S. Route 541 was created in 1931 as a western alternate to US 41 between Palmetto and Tampa; US 41 then followed the present US 301 between those points. In 1938, US 41 was moved from Tampa north to Lutz, and the old route became an extension of US 541. US 541 was eliminated in 1951; the route north from Tampa became US 41 Business, while south from Tampa it became US 41, with old US 41 becoming an extension of US 301.
Major intersections The entire route is in Hillsborough County.

### Macon business loop

U.S. Route 41 Business (US 41 Bus.) begins at the northern terminus of the US 41/US 129 overlap, where it shares a concurrency with Georgia State Route 49 (SR 49). Along the way, US 80/SR 22 joins the concurrency. When US 80/US 129 intersects Walnut Street, US 41 Bus./SR 49 turns left and travels concurrent with SR 22 until the intersection with Second Street, where that route turns north. US 41 Bus. turns south at Spring Street, where SR 49 turns north and it is joined by another concurrency with SR 19. US 41 Bus./SR 19 travels south until turning west at Georgia Avenue until splitting into a one-way pair at the intersection with College Street. From that point, northbound US 41 Bus./SR 49 continues west along Georgia Avenue until it reaches Hardeman Avenue, while southbound US 41 Bus./SR 49 travels east along Forsyth Road then turns north along College Street. After a split-diamond interchange with Interstate 75 (I-75; exit 149) and SR 540 where the northbound routes go over the Joe A. Witherington Bridge while the southbound routes go over the Raymond Berry Oakley III Bridge, the one-way pair ends as Hardeman Avenue and Forsyth Street converge and becomes Vineville Avenue. US 41 Bus. terminates at US 41 and SR 247, while SR 19 continues along Vineville Avenue, joined by US 41 until it terminates in Forsyth. The portion of US 41 Bus. from the northern end of the US 80 and US 129/SR 11 concurrencies to the northern terminus, is part of the National Highway System, a system of routes determined to be the most important for the nation's economy, mobility, and defense.

### Griffin business loop

U.S. Route 41 Business (US 41 Bus.) in Griffin, Georgia is completely concurrent with US 19 Bus. It begins at the intersection of US 19/SR 3 and US 41/SR 7 with SR 155, and follows SR 155 north around Griffin–Spalding County Airport. Then it turns west at SR 16 until it curves onto SR 92 until finally ending at a wye interchange with US 19/US 41/SR 3. All of US 41 Bus. from the southern end of the SR 16 concurrency to the northern terminus is part of the National Highway System, a system of routes determined to be the most important for the nation's economy, mobility, and defense.

### Ringgold truck route

U.S. Route 41 Truck is a short truck detour around a low railroad bridge in Ringgold, Georgia, which is also overlapped by U.S. Route 76 Truck, as well as Georgia State Route 151 and Georgia Route 151 Spur.

### Monteagle, TN-Hopkinsville, KY alternate route

U.S. Route 41 Alternate (signed U.S. Route 41A in Tennessee), as of 2005, has a northern terminus in Hopkinsville, Kentucky, 10 miles (16 km) north of the Tennessee line. It serves the city of Clarksville, Tennessee on its way to Nashville, where it briefly runs concurrently with US 41. It then separates again to serve Shelbyville, Winchester, and Tullahoma before rejoining the main route atop Monteagle Mountain. US 41A runs west of US 41 for its entire length, aside from one mile (1.6 km) in downtown Nashville, where they are concurrent. US-41A is also concurrent with U.S. Route 31A from Nashville to Triune, Tennessee, for a distance of approximately 25 miles (40 km).

### Clarksville alternate route bypass

U.S. Route 41A Bypass (US 41A Byp.) is a bypass of the city of Clarksville, Tennessee, on its south side. It first splits off from the US 41A mainline at 2nd Street and Kraft, following Riverside Drive south, running concurrently with SR 13 and SR 12, along the Cumberland River to an intersection with SR 48 (College Street). It becomes concurrent with SR 48 and they travel south and leave town to an intersection with Cumberland Drive, where SR 13 and SR 48 split off to continue southward. The bypass then curves to the east, still following the river, and enters some neighborhoods and comes to an intersection with Ashland City Road, where SR 12 splits off and goes toward Ashland City. US 41A Byp. then continues east and comes to an end at an intersection with US 41A (Madison Street) and SR 76 (M.L.K. Jr. Parkway). Most of the road is a two-lane highway, occasionally widening to three lanes to accommodate truck traffic on hills.

### Hopkinsville truck route

U.S. Route 41 Truck (US 41 Truck) is a 5.516-mile (8.877 km) truck route designed for thru traffic, mainly trucks, through Hopkinsville, Kentucky. It follows Interstate 169 from exit 7 to exit 12, and Kentucky Route 1682 west from the interchange to U.S. 41 north of Hopkinsville.

### Madisonville-Henderson alternate route

Known and referred to locally as "US 41A" but signed as "Alternate US 41," this highway follows what was the original route of US 41 between the cities of Madisonville and Henderson, Kentucky. It travels largely from east to west from its southern terminus at US 41 on Madisonville's north side until reaching Kentucky Route 814 (KY 814) east of Providence. From that point, the highway begins its turn toward the north, passing mostly through rural areas but also serving the small communities of Dixon and Poole. Major highways intersecting the route include:
* KY 120, which travels from Marion to Slaughters
* KY 132, which travels from KY 120 through Clay and Dixon to Sebree
* KY 56, which begins at the Ohio River near Old Shawneetown, Illinois and connects the Kentucky communities of Morganfield, Sebree, Beech Grove, and Owensboro
* KY 425, which serves as a southern bypass of Henderson
* and US 60, which US 41A joins on the south side of Henderson for its final four miles (6.4 km).
US 41A's northern terminus is at "The Cloverleaf," the interchange between US 60 and I-69/US 41 on Henderson's north side. It is also former US 43.

### Atlanta business loop

U.S. Route 41 Business (US 41 Bus.) was a business route of US 41 that existed in Clayton and Fulton counties. It partially traveled in Atlanta. At least as early as 1919, SR 3 traveled on essentially the same path as it currently does in the northern part of Clayton County and the southeastern part of Fulton County. By the end of 1926, US 41 had been designated on the entire length of SR 3 in these counties. The segment of the highway from just north-northwest of the Henry–Clayton county line to Marietta had a "completed hard surface". By the end of 1929, US 19 was designated on SR 3 in the two counties to the main part of Atlanta.
In 1953, US 19/US 41/SR 3 was shifted eastward onto the "Expressway" (the precursor of Interstate 75 (I-75)) in the southern part of Atlanta, traveled west on Lakewood Avenue, and then resumed the northern path. The former path became US 19 Bus./US 41 Bus. By the end of 1965, US 19/US 41/SR 3 was shifted onto the former path of US 19 Bus./US 41 Bus. in the Atlanta area.

### Atlanta–Marietta alternate route

U.S. Route 41 Alternate (US 41 Alt.) was an alternate route of US 41 that existed from Atlanta to Marietta, Georgia. It traversed portions of Fulton and Cobb counties. At least as early as 1919, SR 3 traveled on essentially the same path as it currently does in these two cities. By the end of 1926, US 41 had been designated on the entire length of SR 3 from Atlanta to Marietta. This entire portion of US 41/SR 3 had a "completed hard surface". By the end of 1929, US 19 was designated on this segment of highway.
Late in 1937, SR 3 was split into two parts between Atlanta and the northwest part of Marietta. By the end of the year, SR 3W was established, traveling northwest with US 41 on Marietta Street and Old Marietta Road. By the end of 1946, SR 3W in Atlanta and Marietta was redesignated as part of the SR 3 mainline. By February 1948, the segment of US 41 on SR 3W in this area was redesignated as US 41 Alt. By April 1949, US 41 Alt. was redesignated as US 41 Byp.

### Atlanta–Marietta bypass route

U.S. Route 41 Bypass (US 41 Byp.) was a bypass route of US 41 that existed from Atlanta to Marietta, Georgia. It traversed portions of Fulton and Cobb counties. At least as early as 1919, SR 3 traveled on essentially the same path as it currently does in these two cities. By the end of 1926, US 41 had been designated on the entire length of SR 3 from Atlanta to Marietta. This entire segment of US 41/SR 3 had a "completed hard surface".
Late in 1937, SR 3 was split into two parts between Atlanta and the northwest part of Marietta. By the end of the year, SR 3W was established, traveling northwest with US 41 on Marietta Street and Old Marietta Road, while SR 3E traveled north-northwest on Hemphill Street and Northside Drive. By the end of 1946, SR 3W was redesignated as part of the SR 3 mainline. By February 1948, the segment of US 41 on SR 3W in this area was redesignated as US 41 Alt. By April 1949, US 41 Alt. was redesignated as US 41 Byp. By the middle of 1950, US 41 Byp. was redesignated as part of the US 41 mainline.

### Atlanta–Marietta temporary route

U.S. Route 41 Temporary (US 41 Temp.) was a temporary iteration of US 41 that existed from Atlanta to Marietta, Georgia. It traversed portions of Fulton and Cobb counties. At least as early as 1919, SR 3 traveled on essentially the same path as it currently does in these two cities. By the end of 1926, US 41 had been designated on the entire length of SR 3 from Atlanta to Marietta. This entire segment of US 41/SR 3 had a "completed hard surface".
Late in 1937, SR 3 was split into two parts between Atlanta and the northwest part of Marietta. US 41/SR 3 traveled northwest on the original path, while SR 3E traveled on a more easterly path between the two cities. SR 3E's path from SR 120 in the east part of Marietta to US 41/SR 3 in the northwestern part of the city had completed grading, but was not surfaced. The rest of SR 3E was under construction. By the end of the year, SR 3E traveled north-northwest on Hemphill Street and Northside Drive. All of SR 3E in the northern part of Atlanta was hard surfaced. From the north part of the city to the northwest part, the highway had completed grading, but was not surfaced.
