One of the first sections of Interstate Highway to be built in the country was a section of four-lane which bisected downtown Winston-Salem, NC. The project was completed in 1955,
Because of Business 40’s age and outdated design standards, as well as increasing traffic volumes and wrecks, N.C. Department of Transportation decided in 2006 to rebuild the section of Business 40 from west of Fourth Street to east of Church Street – a distance of 1.5 miles.
The new Business 40, expected to be completed in 2020, will meet current design standards so that it can function safely and effectively for the next 50 years – the typical lifespan of an interstate highway. Construction costs are $99.2 million.
