| Durham's not a control city of I-40 but I-85! The routes do run concurrently a great distance, requiring both highway's control cities to be shown on signs together (Greensboro for south/west, Durham for I-85 north, and Raleigh for I-40 east). On I-40 eastbound on the west side of Greensboro you can clearly see this distinction with their sign for "I-40 East, Greensboro, Raleigh", not Durham. |
