History: The freeway that is now NC 147 was shown as a dotted line on the 1962 Durham County map, running from US 70 Bus Hillendale Blvd just west of Erwin southeast through Durham to about Briggs Rd, then cut east to end at US 70 near the east end of US 70 Bus.
The 1968 Durham County map shows the dotted line extended south to SR 1121 inside the RTP. The segment's original routing over to US 70 remained a dotted line as well, and is today under design as the East End Connector.
The first official map to show it in any way was the 1968 issue, as under construction from Chapel Hill Ave southeast to NC 55.
The 1969 Official shows construction extending southeast to RTP.
The 1970 Official shows the freeway open from Chapel Hill Ave to NC 55.
In 1973 construction extended northwest to Erwin Dr.
In 1974, the freeway was opened from NC 55 to what is now I-40 (unnumbered freeway then).

Between 1985-87, the freeway construction began again northwest to US 15-501.
In May 1987 (NCDOT) NC 147 was assigned to the freeway and the new section out to US 15-501.
Around 1992, NC 147 was opened northwest to US 15-501 and construction was extended northwest to I-85.
In Feb 2001 (NCDOT), NC 147 was opened to I-85, although official maps as early as 1997 show it as a completed freeway.
In Sept 2011 (NCDOT), NC 147 was extended south as a toll road to NC 540, as part of the Triangle Expressway.

The 1st NC 147 was created in June 1978 as a replacement of SR 2404/2174/1009 from NC 97 near Zebulon east to US 264 Sims. This had previously been the mainline US 264.
By the end of 1978 it appears this became US 264 Business. Today it is US 264-A.

Comment: NC 147 is shown on officials back to 1987 as being the Buck Dean Durham Freeway. Maps before that just labeled it "freeway" and "expwy". Steffora reported it was called East-West Expwy prior to this.
NC 147 ended at I-40 per the current on-line NCDOT Durham County map. The stub over to Alexander Blvd was shown as SR 2145.
NC 147 has exit numbers.
