|Get started||State Line|
According to watchtutorials, US 231 is a US Highway in the US state of Tennessee. The road forms a north-south route through the center of the state, from the Alabama border through Murfreesboro to the Kentucky border. US 231 is 193 kilometers long in Tennessee.

US 231 bisects the state from south to north and intersects two Interstate Highways, I-24 and I-40. The largest city on the route is Murfreesboro, and the route is roughly two-thirds divided between the Alabama border and Murfreesboro. North of Murfreesboro is US 231 single lane. The route avoids the Nashville metropolitan area and runs east of it. US 231 also crosses the Cumberland River.
US 231 was one of the original US Highways of 1926, but at the time it only ran in Florida and Alabama. In 1952 the northern terminus was extended far north from Montgomery, Alabama to St. John, Indiana. This established the current route through Tennessee.
Parts of the route were later upgraded to a 2×2 divided highway or 5-lane road with a center turn lane. The southern section between the Alabama and Fayetteville border was widened to a 5-lane road with a center turn lane in or before the 1980s. Around 2000, US 231 between Shelbyville and Murfreesboro was widened to 2×2/5 lanes.
US 27 in Tennessee
According to Citypopulationreview, US 27 is a US Highway in the US state of Tennessee. The road forms a north-south route in the center of the state and runs from the city of Chattanooga on the Georgia border to Winfield on the Kentucky border. US 27 is a freeway in Chattanooga . The total route is 232 kilometers long.
US 27 at Graysville, 25 miles north of Chattanooga.
US 27 crosses the Georgia – Tennessee border in the town of Chattanooga and then continues on to Interstate 24, the highway from Nashville. The US 27 and I-24 are then double-numbered for 3 kilometers after which the US 27 turns north and forms a highway itself. This highway section is 37 kilometers long. The highway runs in 2×3 lanes along the west side of downtown, then crosses the Tennessee River. The highway then serves the Chattanooga suburban area north of the city. At Soddy Daisy the SR-111 exits, this is the highway to Cookeville. US 27 then ends as a highway and continues as a 2×2 divided highwayfurther, parallel to the Tennessee River. One passes through Dayton, a small town, and then reaches Rockwood, where one crosses Interstate 40. The road then travels north through less populated areas to Winfield on the Kentucky border.
US 27 was one of the original US Highways of 1926. However, US 27 did not run through Tennessee at the time, which followed two years later when the southern terminus was extended to Chattanooga. A further southward extension followed in 1934, completing the entire Tennessee route.
The route of US 27 was proposed in the 1960s as Interstate 175, which was to run from Chattanooga to Lexington, Kentucky, as Corridor J of the Appalachian Development Highway System (AHDS). Much of the route in Tennessee was later redesigned with 2×2 lanes, but not as a highway. The route would be impractical mainly north of I-40 due to the mountainous terrain. The plans never got much further than a $3 billion cost estimate.
US 27 originally had limited 2×2 or 5 lane routes outside the Chattanooga area. In the mid-2000s, a fairly long stretch from Dayton to Rockwood was widened from a single-lane road to a 2×2 divided highway or a 5-lane road with a center turn lane. In the 2018-2019 period, a 10-kilometer stretch in the Appalachian Mountains north of Harriman was widened to 2×2 lanes.
US 27 in Chattanooga.
In 1959 the PR Olgiati Bridge over the Tennessee River in Chattanooga was opened. The freeway was built through Chattanooga in 1960-1963, along with the connecting I-24. Between 1975 and 1977, an eight-mile stretch of freeway was constructed north of Chattanooga, between SR-153 and SR-319, in the Soddy Daisy area. The missing section between US 127 in Chattanooga and SR-153 south of Soddy Daisy was originally supposed to have been built in 1980, but construction on this 14-kilometer stretch was delayed until 1987-1989. In the early 1990s, the highway section was extended another 2 kilometers to the north with the construction of State Route 111.
In 2002, the PR Olgiati Bridge over the Tennessee River was widened to 2×3 lanes. Between 2012 and early 2015, a short 3-kilometer stretch between the bridge and Signal Mountain Road was widened to 2×3 lanes. The project was completed on March 6, 2015. Between 2016 and 2021, the southern section of the highway was widened, a 3 km stretch between the interchange with I-24 and the Olgiati Bridge. The project was largely completed by February 2021.
Near the center of Chattanooga, 70,000 vehicles a day drive, decreasing slowly north to 36,000 at the north end of the freeway section.
A short stretch through Chattanooga is an unsigned Interstate Highway, namely Interstate 124.
