A4042 road


The A4042 is a trunk road that runs from Abergavenny to Newport in south Wales.
Starting at the junction of the A40 and A465 south of Abergavenny, the A4042 travels south towards Little Mill north of Pontypool. This section is a single carriageway and is winding and undulating. From Little Mill onwards the road is dual carriageway, bypassing Pontypool and Cwmbran before crossing the city boundary into Newport. The road has a junction with the M4 motorway and south from there loses its primary status and becomes an urban road. The first section of which, Heidenheim Drive, is an elevated roadway through the Crindau district. The road then becomes the Kingsway that passes through Newport city centre, and continues on as Usk Way until its junction with the A48 Southern Distributor Road to the south of Newport.

History

In the 1920s, the A4042 only ran between Newport to Pontypool. From Croesyceiliog it ran through the village of New Inn. From the mid-1930s the road was extended to Abergavenny.
Due to major congestion in and around Cwmbran and Pontypool, during the mid-1980s and through into the 1990s phases of dual carriageway building replaced the A4042 and created new junctions into Cwmbran and Pontypool.
