Fel y nodwyd uchod, mae ffordd gyswllt Dwyrain Bae Caerdydd a gwelliannau ar hyd yr M4 yn bwysig iawn ar gyfer llwyddiant Ardal Fenter Canol Caerdydd. Yn yr un modd, bydd gwelliannau i Five Mile Lane a datblygu gorsaf reilffordd newydd ac estyniad i linell Glynebwy yn fanteisiol i Ardaloedd Menter Sain Tathan - Maes Awyr Caerdydd a Glynebwy.
As noted earlier in this statement, the Eastern Bay link and improvements along the M4 have an important role to play in stimulating the Central Cardiff Enterprise Zone.  Similarly, improvements to Five Mile Lane and the development of a new railway station and line extension to Ebbw Town will benefit the Enterprise Zones in St Athan – Cardiff Airport and at Ebbw Vale respectively.
