District of Rhymney Valley
Welsh: Cwm Rhymni
|• Succeeded by||Caerphilly County Borough|
From Glamorgan came:
- The urban district of Caerphilly, less Taff's Well ward
- The urban district of Gelligaer, except the Bedlinog ward
- Part of Cardiff Rural District (the parishes of Llanfedw, Rhydygwern, Rudry and Van.
From Monmouthshire came:
- The urban district of Bedwas and Machen
- The urban district of Rhymney
- Part of Bedwellty urban district, (Aberbargoed, Cwmsyfiog, New Tredegar and Phillipstown wards)
In 1996 the district was abolished, with its area becoming part of the unitary Caerphilly County Borough.
The district council inherited the municipal bus fleets of Bedwas and Machen, Caerphilly and Gelligaer urban district councils. The united operation was given a dark brown, cream and gold livery, and ran operations throughout the valley and into Merthyr Tydfil and Newport.
With bus deregulation in 1986 the buses passed to Inter Valley Link Limited, owned by the district council at "arms length". Competition was very strong in the South Wales Valleys, and Inter Valley Link was sold to National Welsh Omnibus Services on 21 March 1989. National Welsh subsequently went into receivership in 1991.
