According to Iamaccepted, US 421 is a US Highway in the US state of Tennessee. The road forms an east-west route through the east of the state, from the North Carolina border to the Virginia border at Bristol. US 421 is 69 kilometers long.

Travel directions

US 421 in North Carolina comes from Boone and heads north to Mountain City and then west to Bristol. US 421 is Tennessee’s easternmost US Highway and is largely a single-lane highway through the Appalachian Mountains. The road leads over two mountain passes, the 1,177 meter high Sandy Gap and then the approximately 1,030 meter high Low Gap. The route crosses Holston Lake where the road merges with US 11. US 421 in Virginia continues to Pennington Gap.

History

US 421 was added to the network in 1930, but at the time only ran in North Carolina. US 421 then began in Boone, on the east side of the Appalachian Mountains. In 1932 the route was extended to Cumberland Gap, Virginia, with US 421 running a short distance through the extreme northeast of Tennessee.

The bridge over the Holston River was built in the period 1949-1950, this bridge was built because of the construction of a dam that created Holston Lake. The only upgrade of US 421 was a short stretch of 2×2 divided highway south of Bristol that was completed over a new route between 1984-1986.

US 43 is a US Highway in the US state of Tennessee. The road forms a north-south route in the central south of the state, from the Alabama border to Columbia. US 43 is 93 kilometers long in Tennessee.

Travel directions

US 43 in Alabama comes from Florence and heads north as a 2×2 divided highway to Columbia, where US 43 ends at US 31. The route is almost entirely a 2×2 road, although parts are also 5-lane with center turn lane. The route leads through semi-wooded area with some agriculture as well. There is a northern bypass around Columbia, but you have to go through the center of Lawrenceburg.

History

US 43 was added to the network in 1934, but at the time only ran in Alabama. In 1939, the northern terminus was changed from Greenhill, Alabama to Columbia, Tennessee, creating the current route. In later years, the terminus of US 43 has been modified on a small scale in and around Columbia.

The northern part of the route has been rerouted on a large scale. Originally there was only a diversion at Mount Pleasant, which was extended to the west side of Columbia in the late 1980s and around the north side of Columbia in the early 1990s. Of this 17-mile route, only the Mount Pleasant and Columbia diversions were made directly with 2×2 lanes, the intermediate section was widened to 2×2 lanes in the early 2000s.

At the end of the 1990s, the section between Summertown and Mount Pleasant was also widened to 2×2 lanes, because of the hilly landscape this section was laid out on a new route. The section between Lawrenceburg and Summertown has already been widened to 4 lanes before that. In the early to mid-2000s, the southern portion between the Alabama and Lawrenceburg borders was widened to a 5-lane center turn lane. This meant that the entire US 43 in Tennesee had at least 4 lanes.
