NC 885 begins at the interchange with NC 540. The whole route carries the moniker of the
Triangle Expressway, which it inherits from the portion of NC 540 south of the aforementioned interchange. It has a single interchange with Davis Drive and Hopson Road between its termini. NC 885 ends at the interchange with I-40, at which I-885 promptly begins. Running north on the Durham Freeway (former NC 147) through the
Research Triangle Park, three closely-spaced interchanges link the route to East Cornwallis Road, T.W. Alexander Drive, and Ellis Road. At the Durham city line, NC 147 begins and diverges toward downtown Durham, while I-885 heads northeast on the East End Connector before joining US 70, curving to the northwest concurrent with the latter route. The freeway turns due north as it comes to
US 70 Business (US 70 Bus)/
NC 98 at a junction that was reconstructed as a compressed
diamond interchange. After continuing north and meeting Cheek Road, the Interstate ends at a
semi-directional T interchange with its parent route, I-85. ==Tolls==
