Major
Intersections:

NC 96 while multiplexed with US 64 in Zebulon.
NC 97 just outside Zebulon.
NC 39 2 miles east of Zebulon.

History:

264 hasn't changed much since its introduction in the early '30s.  The only differences that I can tell is that there is an old routing of 264 (signed Alternate 264 in Franklin and Nash counties; unnumbered in Wake) paralleling the 264 freeway outside Zebulon, and it didn't extend all the way to Raleigh (it ended at the US 64 interchange) until 1995.

Comments:

I had originally thought that 264 would take over the New Bern Ave. routing by itself once the 64 bypass opened, but that route carries an extension of Business 64 instead. 264 continues to run along the new bypass with 64, and ends at the Beltline (complete with an END 264 sign).

The only reason I can think of that 264 runs with 64 from Zebulon west is that people heading to Greenville and Wilson can follow one route number from Raleigh to wherever they're going. It makes enough sense, except I wonder how people found their way to points east before 264 was extended along 64 westward...

How many roads begin and end multiplexed with the same highway?  264 does--its other end (along with US 64's) is at US 158 and NC 12 in Nags Head.
