|Route outline (key)|
The B4283 is a short B-road near the south Welsh coast.
It starts at a roundabout on the A4229 South Cornelly Bypass, with the road into the village being unclassified. Our road then goes in a Northerly direction, passing under the M4 before going through North Cornelly. It crosses the grass-covered sand dunes of the Kenfig Burrows before passing under the Cardiff-Carmarthen Railway Line and then another freight-only line. The road then runs parallel to the M4 for about a mile before ending on the A48 at Cwrt-y-Defaid.
Most of the above was unclassified in 1922. As originally defined, the B4283 started on the A48 in Pyle and ran south via North Cornelly (along a short section still numbered B4283) before continuing on to end on the B4282 on the northern edge of Porthcawl.
In the early 1920s the road from North Cornelly to Gael was classified and numbered B4433. In 1935, this road was renumbered as a spur of the B4283 - and round this time the southern end of the B4283 was extended into Porthcawl as the A4106 (the renumbered B4282) was rerouted.
Most of the original section of the B4283 has now been upgraded to Class I status, becoming the A4229, leaving just the 1935 extension as the B4283.
