From the opening of a 1998 Greensboro News & Record Article:
"Say goodbye to U.S. 29. Say hello to Interstate 785.A few things have changed in the nine years. I'd love to say US 29 has now become fully integrated as Interstate 785, but that's not the item that is different today than nine years ago. Here's the change....North Carolina U.S. Representative Richard Burr is now North Carolina U.S. Senator Richard Burr.
In a name change billed as an enhancement of "economic development," Reps. Virgil Goode of Virginia and Richard Burr of North Carolina will speak today at a ceremony marking the designation of U.S. 29 as part of the interstate highway system.It begins at 10:30 a.m. at the Piedmont Triad Visitors..."
Other than that, there are a few "Future Interstate 785 Corridor" signs and nothing else. And it'll be that way for at least oh 10, 20, maybe 30 more years. I'd love to see the economic impact and development that has resulted from this designation.
Can "Future" Interstates be canceled?
