Dixie Highway

The Dixie Highway was a United States automobile highway, first planned in 1914 to connect the US Midwest with the Southern United States. It was part of the National Auto Trail system, and grew out of an earlier Miami to Montreal highway. The final result is better understood as a network of connected paved roads, rather than one single highway. It was constructed and expanded from 1915 to 1927.

The Dixie Highway was inspired by the example of the slightly earlier Lincoln Highway, the first road across the United States. The prime booster of both projects was promoter and businessman Carl G. Fisher. It was overseen by the Dixie Highway Association, and funded by a group of individuals, businesses, local governments, and states. In the early years the U.S. federal government played little role, but from the early 1920s on it provided increasing funding, until 1927 when the Dixie Highway Association was disbanded and the highway was taken over as part of the U.S. Route system, with some portions becoming state roads.

U.S. Route 1 in Florida

U.S. Route 1 (US 1) in Florida runs 545 miles (877 km) along the state's east coast from Key West to its crossing of the St. Marys River into Georgia north of Boulogne, and south of Folkston. US 1 was designated through Florida when the U.S. Highway System was established in 1926. The road is maintained by the Florida Department of Transportation (FDOT).

From its national southern terminus in Key West, US 1 carries the Overseas Highway—the Keys main highway north to the mainland, entering South Florida. From South Florida to Jacksonville, US 1 runs close to the coastline of the Atlantic Ocean and the Intracoastal Waterway, generally east of I-95 and west of State Road A1A, running roughly parallel with both roads. North of Jacksonville, US 1 curves inland towards the St. Mary's River as it enters Georgia.

As is the case with all Florida roads with Federal designations, the entirety of US 1 has a hidden Florida Department of Transportation designation:

U.S. Route 31W

U.S. Route 31W (US-31W) is the westernmost of two parallel routes for U.S. Route 31 from Nashville, Tennessee to Louisville, Kentucky. At one time, it split with U.S. Route 31E at Sellersburg, Indiana, crossing into nearby Louisville via the Kentucky & Indiana Terminal Bridge.

Route description

US 31W begins in Nashville, at an interchange with Ellington Parkway and US 31 / US 31E. The route continues west as Spring Street, signed with US 41, US 431, and SR 11. US 31W, US 41, US 431, and SR 11 continue north onto Dickerson Pike, closely paralleling I-24 through Nashville. At an intersection with Trinity Lane, all the routes but SR 11 and US 41 split from US 31W and continue west, while US 31W continues north, away from I-24. The roadway has an interchange with I-65 and SR 155 before an intersection with SR 45 in Bellshire Terrace. The highway passes through Goodlettsville, where US 31W splits from the other two routes and crosses I-65; it also passes through White House, Tennessee.
