Roger of 'The Rhondda' !
I am a LOCAL RESIDENT in the NEAR VICINITY to this LOCATION !

N.B. Road layout changed here for this location recently : HEADING in a NORTHERLY DIRECTION, there is now NO RIGHT TURN from the A4058 onto the B4278 at this set of Traffic Lights ( Right Turn Filter Lane / Traffic Light Signal has BEEN REMOVED ! ) . . . . . . to get round this minor problem, CONTINUE HEADING NORTH to the following Roundabout Junction ( A4058 / A4233 ) & take the 4th EXIT from this Roundabout, to get back to the PREVIOUS SET of Traffic Lights, this time from a NORTHERLY DIRECTION & then TURN LEFT onto the B4278 to enable you, to enter & go around the PORTH ONE-WAY SYSTEM from this NORTHERLY DIRECTION / POSITION / LOCATION !

N.B. "Good Luck !"
