|Route outline (key)|
The original route of the B4237 bypassed Newport to the south.
The road started on the A437 (renumbered A48 in 1935) Chepstow Road and headed south along Somerton Road and west along Cromwell Road to Corporation Road. The section of Corporation Road north of Spytty Road was later renumbered A455.
Continuing south the B4237 turned into Stephenson Street to meet the Newport Transporter Bridge. As a toll bridge this did not receive a number in the 1922 classification and so the road ended here, with the B4239 continuing on the far side. Sanity prevailed later on (at the latest by 1935 when the B4239 number was used elsewhere) and the B4237 was extended over the bridge and what was the B4239 to end on the A4052 (later A4042) Alexandra Road.
The original B4237 became unclassified in the 2000s on the opening of the Newport Southern Distributor Road, which largely paralleled its route.
