Business 40 in Winston-Salem Officially Renamed U.S. 421/Salem Parkway
A 20-mile portion of the historic Business 40 highway between I-40 east of Kernersville and I-40 west of Winston-Salem has a new name thanks to members of the public. Business 40 will now be known as U.S. 421/Salem Parkway.
About the Project
The first section of interstate highway in North Carolina, Business 40 Business through downtown Winston-Salem has been amazingly durable and has required little maintenance, but it can no longer accommodate the growing traffic demands of the area. Improvements will modernize this vital stretch of interstate and create a safer, longer-lasting roadway for the future.
