Florida US 19 first entered Florida in 1929. It underwent two route shifts, the first in 1933 and the second in 1946, which adjusted it to its current alignment. US 19 was extended to its southern terminus of Memphis in September 1954, when the original Sunshine Skyway Bridge opened to traffic. Starting around 1956, US 19 was four-laned, initially in the Perry area, working north toward the Georgia border. The entire route in Florida was four-laned by 1972. The planned St. Petersburg–Clearwater Expressway, or Pinellas Beltway, would have followed the current alignment of
US 19 Alt. from
I-275 to
Clearwater, Florida. The intersection of Seminole Boulevard and Bay Pines Boulevard is a remnant of this proposed road. The beltway road was proposed in 1974, but it was dead by 1980.
North Carolina In North Carolina, US 19 was
North Carolina Highway 10 (NC 10) from the Georgia state line to Asheville, NC 29 from Asheville to
Madison County, NC 69 to a point near the Tennessee state line, and either NC 194 or NC 694 for a short distance south of the Tennessee state line. The original US 19 in
Yancey,
Mitchell, and
Avery counties mostly followed the route now designated US 19E. US 19W in Yancey County was US 19-23 in 1935, and what is now US 19E was US 19A. The US 19E and US 19W designations have been used since 1930. Prior to 1948, US 19 between
Ela and
Waynesville essentially followed the route of present-day US 74. Then, this road was called
US 19A and the section of
NC 28. From Ela to
Cherokee and the section of
NC 293 from Cherokee to near Waynesville became US 19. Improvements were made, including a new section of highway west of
Lake Junaluska. Around 1956, US 19/US 23 was widened to four lanes from Lake Junaluska to
Canton. By 1970, a section of US 19 west of
Murphy, also designated
US 64 (and later
US 74), was widened to four lanes. In January 1983, after improvements to US 19A had made it similar to an
Interstate Highway, the state proposed designating US 19A as US 19 Bypass. At one point, changing US 19A to US 19 was considered, but businesses in
Maggie Valley opposed the idea of their highway being changed to US 19A. US 19A became the
Great Smoky Mountains Expressway.
Tennessee US 19 originally went from the North Carolina state line to
US 511. In 1928, US 19 was extended with US 511 to Bristol and into Virginia. In 1930, US 19 south was truncated to Bluff City (the current
State Route 44 [SR 44]/
SR 390 junction), as US 19E was assigned to US 19 south to North Carolina. This is still US 19E except Old Highway 19E/Buck Creek Road east of Shell Creek; Carter Street, Main Street, Conway Street, and Cloud Land Drive in Roan Mountain; Crabtree and Old Rock Quarry roads west of Roan Mountain; Little Mountain Church Road; Holtsclaw Road; Herman Johnson Loop; J D Whitehead Road; Old Highway 19E, Schoolhouse Road, and Dave Simerly Road in Tiger Valley; Rittertown Road south of Hampton; Church and 1st streets through Hampton; and Mill Pond Road in the Valley Forge area. The quite winding alignment where it crosses the Doe River twice is completely abandoned; State Line Road/Johnson Avenue/Sycamore Street/Broad Street through Elizabethton, plus today's
SR 400 and Bristol/Elizabethton/Old Elizabethton highways to Bluff City. In 1931 or 1932, US 19 south was extended over US 19W to the new US 19E/US 19W split in Hillcrest (the current SR 44/Elizabethton Highway junction)
Virginia Although an original U.S. Highway, US 19 does not appear on the 1926 official road atlas (which shows other U.S. Highways) nor the 1927
Clason road atlas. It does appear on a mid-1927 official map. It ran generally as it does today. In this routing, US 19 was added to US 11 and State Route 10 (SR 10) from the Tennessee state line to
Abingdon, SR 106 from Abingdon to
Hansonville, SR 112 from Hansonville to
Lebanon, and SR 11 from Lebanon to the West Virginia state line. Initially, US 19 entered Virginia via Pennsylvania Avenue in Bristol, Tennessee, then used State Street west to Front Street north to Spencer Street northeast to Mary Street east to Goodson Street north to Danville Avenue east to Fairview Street north to Massachusetts Avenue east to Texas Avenue north, which became Old Abingdon Highway ran back into US 11/US 19 near the I-81 interchange. US 19 followed today's US 11 approaching Abingdon, then used Colonial Avenue and crossed the railroad to modern US 11 at roughly the Bytt Street location, then
US 58 Alt. northwest. US 19 followed today's US 19/US 58 Alt. to Hansonville except SR 766 near Abingdon, SR 633 loop at Butts, SR 775 at Greendale, and SR 876/SR 802 at Holton. Leaving Hansonville, US 19 used today's US 19 up to SR 674, then abandoned alignment on the north side to Sunset Drive, US 19, SR 841 (except initially used SR 758 loop) to
US 19 Business (US 19 Bus.), some of US 19 Bus., Gilbert Street/Old Fincastle Road, SR 82, and US 19 Bus. through Lebanon. East of Lebanon, US 19 used SR 656 loop back to US 19. After a brief stretch of today's US 19, US 19 followed the SR 872 loop near SR 80 eastbound. US 19 followed more of today's US 19 but near SR 80 westbound stayed north of the creek on Old Rosedale Highway and some abandoned alignments until around SR 644. East of here, US 19 more closely followed it current path although in the field it appears old alignment pieces are visible to the north side. Before SR 369, US 19 originally used SR 770 to cross into Tazewell County, then SR 609 north back to US 19. US 19 followed its current path to Claypool Hill except it used the SR 705 loop. At Pounding Mill, US 19 used SR 637 but otherwise followed US 19/
US 460 and then
US 19 Bus./
US 460 Bus. to SR 16 Alt. Initially, US 19 followed Old Fincastle Turnpike in western Tazewell, then current US 19 Bus. through Tazewell, then Ben Bolt Road east to SR 61. US 19 then followed SR 61 north to SR 678 (Market Street). US 19 followed SR 678 north to SR 645 east which used to connect back to modern US 19/US 460. US 19 followed today's US 19 to Bluefield, West Virginia, except SR 781, SR 680 loops in
Springville, SR 665, and SR 744/SR 1520 Shannandale. There are other visible unnumbered loops that are visible to the north side of US 19/US 460. In Bluefield, US 19 used Greever and East streets.
West Virginia Appeared in December 1926 as an original U.S. Highway, replacing West Virginia Route 4 (WV 4) from Bluefield to
Westover and WV 30 from Westover to Pennsylvania. The original description of US 19 in the 1925
West Virginia Department of Transportation (WVDOT) annual report had US 19 ending at
US 60 in
Gauley Bridge and the 1926 official maps of both Virginia and West Virginia show this, but, by the time the U.S. Numbered Highway System went live in late 1926, US 19 did extend all the way through West Virginia. The road from
Beckwith to US 60 was completed as new construction in 1926. It is unclear if US 19 was briefly part of the old route via Kanawha Falls which became part of WV 61 (now County Route 13, or CR 13). In 1929, US 19 was rerouted at Belva to the current WV 39 crossing of Twentymile Creek. The old route used today's CR 16/6 which no longer crosses the railroad and abandoned routing northwest to the Creek crossing which remained many decades past but is now gone along WV 16 north of the WV 39 junction. In about 1931, according to that year's WVDOT annual report, US 19/US 21 was removed from CR 19/19 (Cherry Creek Circle) and CR 119/8 (Lamar Circle) in Cherry Creek; CR 19/17 (Marshall Circle) all between
Ghent and
Shady Spring; also CR 19/28 (Ransom Drive), CR 119/20 (Little Vine Drive), and CR 19/14. Old US 19 loops above Shady Spring. Also, in about 1931, according to that year's WVDOT annual report, US 19/US 21 was rebuilt from
Skelton to
Mount Hope and removed from CR 19/5 and CR 4 (Prosperity Road) through
Prosperity; CR 16/68 (Bradley School Road); and CR 19/1 (Maple Lane; no longer connects to), CR 1/25, CR 19/43 (Sherwood Road), and CR 21/8 (Sherwood Heights Road). In about 1934, US 19 was given a new routing between Bluefield and
Princeton. The old route became CR 25 (Old Princeton Road) out of Bluefield; CR 25 (Mercer Mall Road) to
Edison (some of this is now WV 123); WV 71 legs (now CR 19/33 [Maple Acres Road] to Glenwood; Glenwood/Green Valley/Old Bluefield roads [CR 19/29] from Glenwood to Princeton). Also, in about 1934, according to that year's WVDOT annual report, the original Beckley Bypass was completed. It is referred to as "Alternate Route" through at least 1936. Then, by 1940, it appears mainline US 19 was moved onto it, leaving behind US 19 Alt. (now WV 16, CR 21/5, more WV 16, and all of WV 210) through Beckley. Also, in about 1934, according to that year's WVDOT annual report, US 19/US 21 was put on mostly new construction from
Oak Hill to
Fayetteville, leaving behind CR 19/2 (Broadway Avenue) and CR 19/1 (Nickelville Road). In about 1935, according to that year's WVDOT annual report, US 19/US 21 was removed from Covington and Piney Creek roads near
Raleigh (south edge of Beckley) Also, in about 1935, according to that year's WVDOT annual report, US 19/US 21 was put on new construction between
Glen Jean and Oak Hill leaving behind CR 20 (now CR 21/20) from Glen Jean to Whipple Junction and CR 15 from Whipple Junction to Oak Hill. Also, in about 1935, according to that year's WVDOT annual report, US 19/US 21 was removed from CR 21/4 (Old Court Street) north of Fayetteville. Also, in about 1935, according to that year's WVDOT annual report, US 19 was removed from Colasessano Drive which no longer crosses Buffalo Creek to Old Pennsylvania Avenue north of
Fairmont. In about 1936, according to that year's WVDOT annual report, US 19/US 21 was removed from today's CR 119/6 (Sheloh Circle) and CR 119/2 (Madoc Circle) in
Cool Ridge. In 1936 or 1937, US 19 was removed from CR 19/9 and CR 19/10 (Robinson Run Road) in
Bowlby. Between 1947 and 1949, US 19 was rerouted to run directly from Beckley to Summersville as an addition to WV 41. The old route through Fayetteville to Gauley Bridge remained part of US 21 (now WV 16 except US 19 used WV 211 through Mount Hope) while Gauley River to Summersville became an extended WV 39.
Pennsylvania For many years, the
Venango Path was a Native American trail between the
Forks of the Ohio (present day Pittsburgh) and
Presque Isle Bay. This trail follows modern US 19 from Pittsburgh across the
Allegheny River to
Perrysville. It continues to
Wexford and crosses Brush Creek at
Warrendale. Here, the path and modern road separate for a time. The path goes across fields while the road parallels it—from a distance of to the west—for about to Ogle. US 19 in Pennsylvania has maintained a similar alignment for much of its history. In 1928, US 19 was moved to its current route between Pittsburgh and
Meadville. The West End Bridge in Pittsburgh was completed in 1932, and US 19 was realigned to cross the bridge. In 1936, US 19 was moved to its current alignment between
Zelienople and
Harmony. Through the 1940s and 1950s, different parts of US 19 were widened. In 1987, the Phase One project started to connect two sections of Ohio River Boulevard near Western Avenue and Chateau Street. Phase Two of the project included a new interchange between the
Pennsylvania Route 65 (PA 65) expressway (concurrent with US 19 west of the interchange) and the West End Bridge. The bridge was closed for two years for construction but reopened in 1991 while construction finished in 1992. In 2003, the
Pennsylvania Department of Transportation (PennDOT) started a project to build a US 19 tunnel under the
Norfolk Southern Railway, as well as align the West End Bypass with the West End Circle, the intersection of US 19,
PA 51,
PA 60, and
PA 837. The project was completed in 2010. In 2016, a
diverging diamond interchange was built at the intersection of US 19 and I-70/I-79 in
South Strabane Township. PennDOT has started construction on a multilane roundabout at the intersection of
US 6, US 19,
US 322, and
PA 98 in
Vernon Township, near Meadville. Construction was expected to be completed in October 2019. PennDOT has also started construction on an intersection improvement project at the northern intersection of US 19 and
PA 97. PA 97 were realigned to meet US 19 at a 90-degree angle, and new left-turn lanes and traffic signals were installed. Construction was expected to be completed in October 2019. ==Major intersections==
