The C5 is a complicated road. Following several modern developments it has now been severed into many different segments. The road starts on the A520 and follows the western edge of Lisburn. Before long, the road diagonally crosses the A30 and encounters its first break where it meets the modern A519 which cut Nettlehill Road into two parts when it was built. The eastern segment of Nettlehill Road is now merely a dead end stump off of the B101. Moving eastwards, the C5 covers three different parts of Magheralave Road which runs north from the city centre. The southernmost part is terminated upon reaching the entrance to Thiepval Barracks, an army complex through which the road is closed to the public. North of here, the road is severed once again as it reaches the edge of the city on one side of the modern A513 North Lisbon Feeder road. The C5 continues north of the A513 via Derriaghy Road from which the detached dead end stump of Magheralave Road can also be accessed. The final, and perhaps the most straightforward section to describe, simply turns east through Milltown and crosses the A512 to reach the A1 in Derriaghy.
