As work continues on the Business 40 Improvements Project, not only does the corridor get a new name, Salem Parkway, but it also gets new exit numbers.

The current signage shows the Business 40 exit numbers. However, if weather permits, workers will close one lane in either direction of the highway between 9 p.m. and 6 a.m. from Tuesday, Dec. 17 until the morning of Friday, Dec. 20 so they can safely change the exit numbers to show those for U.S. 421.

Crews will begin on eastbound Business 40 at U.S. 52 and work toward Sandy Ridge Road near Greensboro. They will then shift the closure to the westbound side to work back to U.S. 52.

N.C. Department of Transportation Resident Engineer Larry Shaver explained that drivers will not see double exit number signs. Because all of the work will not take place in one night, drivers are likely to notice new U.S. 421 exit signs directly followed by the Business 40 exit signs being replaced.

“We do not want to startle drivers,” Shaver said. “We want to alert them that this is a work in progress and to expect sudden exit sign changes from the new to the old. We anticipate the work from U.S. 52 to the eastern split and back will be complete by the end of the week, depending on the weather. Crews will then move to the west side of the project and change the exit numbers between Cloverdale Avenue and Interstate 40.”

Shaver noted the name Business 40 will no longer be used. Before the project is completed, new signs will show the road to be Salem Parkway/U.S. 421.
