Road network

The A4042 is a trunk road that runs from Abergavenny to Newport in the United Kingdom.

It begins on junction of the A40 and A465 south of Abergavenny and then travels southwards towards Little Mill north of Pontypool. This section is a single carriageway and is notoriously winding and undulating. From Little Mill onwards the road becomes a dual carriageway, passing Pontypool and Cwmbran before crossing the city boundary into Newport. Here the road has a junction (25A) with the M4 motorway and south from there loses its primary status and becomes an urban road. The first section of which, called Heidenheim Drive,[1] is an elevated roadway through the Crindau district. It then becomes a surface street called Kingsway that passes through the city centre, and continues on as Usk Way until its junction with the A48 Southern Distributor Road in the south of the city.
