Title: U.S. Route 1
Content:  U.S. Route 1 or U.S. Highway 1 (US 1) is a major north–south United States Numbered Highway that serves the East Coast of the United States. It runs 2,370 mi, from Key West, Florida north to Fort Kent, Maine, at the Canadian border, making it the longest north–south road in the United States. US 1 is generally paralleled by Interstate 95 (I-95), though the former is significantly farther west (inland) between Jacksonville, Florida, and Petersburg, Virginia. The highway connects most of the major cities of the East Coast—including Miami, Jacksonville, Raleigh, Richmond, Washington, D.C., Baltimore, Philadelphia, New York City, and Boston passing from the Southeastern United States to New England. While US 1

Title: U.S. Route 1 in Georgia
Content:  U.S. Route 1 (US 1) in the U.S. state of Georgia, which is concurrent for almost its entire length with State Route 4 (SR 4), is a highway traversing south-to-north through portions of Charlton, Ware, Bacon, Appling, Toombs, Emanuel, Jefferson, and Richmond counties in the southeastern and east-central parts of the state. In Georgia, the highway originates at US 1/US 23/US 301/SR 15 at the St. Marys River and the Florida state line, where SR 4 and SR 15 reach their southern terminus. It travels to its northern terminus at US 1/US 25/US 78/US 278/SC 121 at the Savannah River and the South Carolina state line in Augusta. Here, SR 10 reaches its eastern terminus.
Title: U.S. Route 1 in New York
Content:  U.S. Route 1 (US 1) is a part of the U.S. Highway System that extends from Key West, Florida, to the Canada–United States border at Fort Kent, Maine. In the U.S. state of New York, US 1 extends 21.54 mi from the George Washington Bridge in Manhattan to the Connecticut state line at Port Chester. It closely parallels Interstate 95 (I-95) for much of its course, and does not serve as a major trunk road within the state. It is not concurrent with any other highways besides I-95 and (briefly) US 9, and few other state highways intersect it. It travels through a variety of different terrain within 
Title: U.S. Route 51
Content:  U.S. Route 51 or U.S. Highway 51 (US 51) is a major south-north United States highway that extends 1277 mi from the western suburbs of New Orleans, Louisiana, to within 150 ft of the Wisconsin–Michigan state line. As most of the United States Numbered Highways ending with "1", it is a cross-country north-south route extending from the Gulf Coast region to the Great Lakes region. Much of the highway in northern Illinois and southern Wisconsin runs parallel to or is cosigned with Interstate 39 (I-39) and much of the route in several states also parallels the Illinois Central Railroad. From LaPlace, Louisiana, 
Title: U.S. Route 1 in South Carolina
Content:  U.S. Route 1 (US 1) is a 170.540 mi north–south United States highway that crosses South Carolina from southwest to northeast and connects the cities of North Augusta, Aiken, Lexington, Columbia, Camden, and Cheraw. The route parallels I-20 closely from the Georgia border to Camden, where I-20 turns to a more directly easterly direction. From Camden to the North Carolina border, U.S. 1 is the highest capacity route through much of the Sandhills region.

Content:  generally the easternmost of the main north-south U.S. Highways, parts of several others occupy corridors closer to the ocean. When the road system was laid out in the 1920s, US 1 was mostly assigned to the existing Atlantic Highway, which followed the Fall Line between the Piedmont and the Atlantic Coastal Plain north of Augusta, Georgia. At the time, the highways farther east were of lower quality and did not serve the major population centers. From Henderson, North Carolina, to Petersburg, Virginia, it parallels I-85. Construction of the Interstate Highway system gradually changed the use and character of US 1, and I-95 became the major north–south East Coast highway by the late 1960s.

Title: U.S. Route 1 in Virginia
Content:  U.S. Route 1 (US 1) is a major north–south U.S. Highway that serves the East Coast of the United States. In the U.S. state of Virginia, US 1 runs north–south through South Hill, Petersburg, Richmond, Fredericksburg, and Alexandria on its way from North Carolina to the 14th Street Bridge into the District of Columbia. It is completely paralleled by Interstate Highways in Virginia – Interstate 85 (I-85) south of Petersburg, I-95 north to Alexandria, and I-395 into the District of Columbia – and now serves mainly local traffic. At its north end, on the approach to the 14th Street Bridge, US 1 is concurrent with I-395; the rest of US 1 is on surface roads.

Content:  line. In 1925, the Joint Board on Interstate Highways created a preliminary list of interstate routes to be marked by the states, including US 1 along the Atlantic. This highway began at Fort Kent, Maine and followed the existing Route 24 to Houlton, as well as Route 15 to Bangor, beyond which it generally followed the Atlantic Highway to Miami. In all states but Georgia that had numbered their state highways, Route 1 followed only 1 or 2 numbers across the state. The only significant deviation from the Atlantic Highway was between Augusta, Georgia, and Jacksonville, Florida, where Route 1 was assigned to a more inland route, rather than
