Special routes of U.S. Route 19

Several special routes of U.S. Route 19 (US 19) exist. In order from south to north, they are as follows.

Brooksville alternate route
U.S. Highway 19 Alternate (US 19 Alt.) was a former segment of US 19 that ran from Bayonte Point to Brooksville, Florida, which only existed for one year. It ran along what is today State Road 52 (SR 52) from Bayonet Point to Gowers Corner, and then turned north along US 41 into Brooksville.

St. Petersburg–Holiday alternate route
U.S. Highway 19 Alternate (US 19 Alt.) is the 40.08 mi former section of US 19 from St. Petersburg to Holiday, Florida.

Beginning at the intersection of 4th Street North (US 92 and SR 687) and 5th Avenue North in St. Petersburg, it runs west of US 19 near the Gulf coast passing through the cities of Seminole, Clearwater, Dunedin, and Tarpon Springs before ending at US 19 in Holiday, Pasco County. It is also the unsigned State Road 595 (SR 595) throughout the entire route. It also runs along much of the Pinellas Trail.

Thomasville–Meigs business loop
U.S. Highway 19 Business (US 19 Bus.) was a business route of US 19 that originally existed from Thomasville to Meigs, Georgia. The roadway that would eventually become US 19 Bus. was established at least as early as 1919 as part of State Route 3 (SR 3) between the two cities. By the end of 1926, two segments of the highway had a "completed hard surface": a segment in the northern part of Thomasville and from approximately Ochlocknee to Meigs. A segment north-northwest of Thomasville had a "sand clay or top soil" surface. By the end of 1929, US 19 was designated on the then-current highway from Thomasville to Meigs.

By the middle of 1930, the entire segment of SR 3 that became US 19 Bus. had a completed hard surface. By the end of the year, the segment from the Florida state line to Thomasville was indicated to be under construction. In January 1932, the entire highway from Thomasville to Meigs had a completed hard surface. In 1934, a segment north-northwest of Thomasville was under construction. By June 1963, SR 333 was designated on US 19 between Thomasville and Meigs. SR 3's Thomasville–Meigs segment was shifted westward onto US 19 Bus. Its former path, on US 19, was redesignated as part of SR 333. By the end of 1965, the northern terminus of US 19 Bus. was truncated to just east of Ochlocknee. In 1982, all of SR 333 that remained was redesignated as SR 300. In 1986, US 19 Bus. was decommissioned.

Albany business loop
U.S. Highway 19 Business (US 19 Bus.) in Albany, Georgia, is concurrent with US 82 Bus. and SR 520 Bus. for its entire length. It begins at exit 2B on the Liberty Expressway and joins westbound US 82 Bus and SR 520 Bus. From there, US 19 Bus./US 82 Bus./SR 520 Bus. turn north at SR 234, which briefly joins the concurrency. The three business routes continue to the north until they end at exit 6 which is the western end of the US 19/US 82 concurrency.

The entire length of US 19 Bus. 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.

Leesburg bypass route
U.S. Highway 19 Bypass (US 19 Byp.) is a 1.8 mi western bypass of the city of Leesburg in Lee County, Georgia, which was completed in 2009. It is concurrent with State Route 3 Bypass (SR 3 Byp.) and briefly with SR 32. The entire length of US 19 Byp. 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. Highway 19 Business (US 19 Bus.) in Griffin, Georgia, is concurrent with US 41 Bus. It begins at the intersection of US 19/US 41/SR 3/SR 7 and 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 19 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.

Atlanta business loop
U.S. Highway 19 Business (US 19 Bus.) was a business route of US 19 that existed in Clayton and Fulton counties, Georgia. 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, or 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.

Dahlonega business loop
U.S. Highway 19 Business (US 19 Bus.) in Dahlonega, Georgia, is concurrent with both SR 9 and SR 52.

Ela–Lake Junaluska alternate route
U.S. Highway 19A (US 19A) was established in 1947, replacing part of North Carolina Highway 28 (NC 28), between Ela and Cherokee, North Carolina, and all of NC 293 between Cherokee and Lake Junaluska, via Soco Gap. In 1948, US 19 and US 19A swapped routes.

Bryson City–Lake Junaluska alternate route
U.S. Highway 19A (US 19A) was established in 1948 when US 19 swapped routes with the previous US 19A between Ela and Lake Junaluska, North Carolina, via Soco Gap. US 19A followed the old alignment of US 19 from Ela, through Dillsboro, Sylva, and Waynesville, to Lake Junaluska. Between 1954 and 1957, US 19A/US 23 was placed onto current routing bypassing Balsam. Between 1958 and 1962, US 19A/US 23 was placed on one-way streets through Sylva; northbound via Main Street and southbound via Mill Street. In 1967, US 19A/US 23 was rerouted on new freeway bypass west of Waynesville; its old alignment becoming US 23 Bus. In 1974, US 19A was placed on new freeway bypass north of Dillsboro and Sylva; its old alignment becoming US 23 Bus. In 1975, the relocation around Sylva was submitted to American Association of State Highway and Transportation Officials (AASHTO) for approval, but was denied by the subcommittee; despite the denial, North Carolina Department of Transportation (NCDOT) left signage as is. In 1976, US 19A was placed on new freeway bypass east of Bryson City, from Alarka Road to US 441; its old alignment from Ela to Whittier was downgraded to secondary road. In 1982, NCDOT submitted a request to AASHTO to switch US 19 and US 19A between Bryson City and Lake Junaluska; but was later withdrawn before the vote. In 1983, US 19A was redesignated US 19 Byp.; despite the change, signage along the route maintained US 19A during and after US 19 Byp. was also eliminated in 1987.

Bryson City–Lake Junaluska bypass route
U.S. Highway 19 Bypass (US 19 Byp.) was established in 1983 as a redesignation of US 19A between Bryson City and Lake Junaluska, North Carolina; this also coincides with the establishment of the Great Smoky Mountains Expressway. In 1987, US 19 Byp. was eliminated in favor for US 74, which was extended west of Asheville the prior year. Despite being officially US 19 Byp., signage along the route remained US 19A throughout, with some signs still marking the route until the mid-1990s.
