Original 1932 route In 1932, the A4050 was a short road along the
Rhymney Valley, connecting
Bargoed with the
A4049 in both directions. Starting on the
A4049 at
Pengam, the road headed west across the river before turning northwards. The road ran through the centre of
Bargoed before detouring west to cross the narrow
Darran Valley. After rejoining the
Rhymney Valley the road continued upstream via
Brithdir to end back on the
A4049 at
Tir-Phil. The original northern end of the
A469 was in
Ystrad Mynach. Later in the 1920s, that road was extended north to meet the A4050 near
Pengam railway station and then, in 1935, the entire A4050 was renumbered as part of a northern extension of the
A469, giving that road the spur that survives to this day.
Bargoed has since been bypassed. ==References==
