King Jr. Boulevard, and then as the John Bragg Highway, the two routes leave the city and continue east through forested areas and farmland for several miles. In the town of Woodbury, the highway intersects with SR 145, and passes through the town as Main Street, also briefly running concurrently with SR 53. The road then winds through foothills before intersecting SR 281, SR 146 (both in the Bluewing community), and SR 287 (in the town of Centertown). Main Street comes to an interchange with SR 380 and SR 55, and US 70S and SR 1 continue northeast on the Bobby Ray Memorial Parkway. The parkway continues along the outskirts of McMinnville, intersecting SR 56 and SR 380. As Sparta Highway, the routes continue east, intersecting SR 30 and SR 288 before passing near Campaign and becoming first Bone Cave Parkway and then Memorial Highway. After several miles, the routes run concurrently with SR 111 before heading due north on Spencer Highway before SR 1 exits from the divided highway. US 70S and SR 111 continue north to the diamond interchange with US 70 and SR 26 just west of downtown Sparta. History Route improvements During the 1980s, the section of the route between Belle Meade and Smyrna was upgraded from two to four lanes. In 1991, the portion from Smyrna to Murfreesboro was also upgraded to four lanes. In the early 1990s, the stretch from Murfreesboro to Woodbury was widened from two to four lanes. Between 1994 and 2002, the section between McMinnville and Sparta was widened to four lanes and a four lane bypass around McMinnville was built. The former routing through downtown McMinnville is now designated State Route 380. In 2006, besides the two-mile (3.2 km) western terminus near Bellevue past Interstate 40 to the intersection with US 70, the only section of US 70S that lacked four lanes was between Woodbury and McMinnville. Construction began outside McMinnville on widening to five lanes (including one left turn lane) for three miles (5 km) as a way to avoid congestion. In 2018, most of the section between McMinnville and Woodbury had been upgraded to a four-lane divided highway. From McMinnville west to where the road starts up the ridge is four-laned. The stretch of highway going through Woodbury proper is still two-lanes. As the remaining two-lane portion will be adjacent to the site chosen in late January 2017
