Interstate 85 Business (I-85 Bus; commonly referred to as Business 85) in the US state of North Carolina is a business loop of Interstate 85 (I-85) which serves several cities in the Piedmont Triad. Route description I-85 Bus, which completely runs concurrently with US Highway 29 (US 29) and US 70, begins at a partial Y interchange with I-85 (exit 87) in Lexington. Heading north for , along with I-285 and US 52, it goes through another partial Y interchange (exit 87) before leaving the freeway. Changing to a semi-limited expressway, it serves as a northern bypass of downtown Lexington, briefly running concurrently with US 64. After leaving the city limits, I-85 Bus heads in a northeast direction in parallel to I-85 further south. After it travels through Thomasville, it enters the city of High Point in Davidson–Randolph county line. Briefly in Randolph County for , it enters Guilford County. East of downtown High Point, I-85 Bus shares a unique three-level diamond interchange with I-74/US 311 before leaving the city limits. At the Greensboro city limit, I-85 Bus completes its journey with a trumpet interchange with I-85 (exit 118). History Established in 1984 as redesignation of Temp I-85, I-85 Bus traveled from Lexington to Greensboro, in a complete concurrency with US 29 and US 70, when I-85 was completed on a more southern parallel routing. In May 2005, I-85 was redirected southeast around Greensboro along the Greensboro Urban Loop; its old routing through Greensboro became an extension of I-85 Bus, extending it from to . The extension included a hidden concurrency along I-85 (between exits 118–120A) before splitting off again with US 29 and US 70. In merging onto I-40 (exit 219), it continued easterly before meeting back with I-85 (exit 227) near McLeansville. For a brief period in 2008, I-40 was also decommissioned through Greensboro and rerouted around the Urban Loop, with its old routing replaced by I-40 Bus, but its former in-town route was eventually restored, resulting once again in a regular and business Interstate sharing the same alignment. In October 2018, I-85 Bus was reverted to its original alignment, ending near Jamestown. The justification was to eliminate a redundant route and decrease the number of routing shields and overhead signs through Greensboro. Temporary Interstate 85 Temporary Interstate 85 (Temp I-85) was established by 1961 as a temporary designation that directed travelers along US 29/US 70, from the
