English: Thank you for raising that. We're fully aware of the importance of the A470 strategic corridor. The section around Trago Mills is currently being investigated and appraised to the requirements of the Welsh transport appraisal guidance, known as WelTAG. Studies are on hold at the present time whilst the unsettled traffic patterns and demand return back to average conditions following the opening of the Trago Mills store, which we know increased demand considerably. The bedding-in period is expected to last about six months, by which time the study will recommence by testing projected trends with those known post-opening of Trago Mills. The sensitivity testing will better inform the appropriateness of the longer term solutions that are proposed. Once the stage 2 studies along the corridor have been completed and appraised, transport interventions to address congestion will be addressed. That's expected to be completed by early 2019, and in the meantime there are medium-term measures to be progressed. The issue about the time limits for planning consent relating to major developments is a matter for local planning authorities to consider. I know the Cabinet Secretary has a consultation out at the moment, and I'm sure that the local authority and you will be responding to that. In this case, as you know, the decision for planning consent was made in 1994 by the Mid Glamorgan planning authority and included highway improvements appropriate to the scale of development at that time, but, as the Member has highlighted, that situation has changed very much. So, the studies will inform improvements in the road once the traffic has settled again.
Welsh: Diolch am godi hynna. Rydym ni'n gwbl ymwybodol o bwysigrwydd coridor strategol yr A470. Mae'r darn o'r ffordd o gwmpas Trago Mills wrthi'n cael ei ymchwilio a'i arfarnu y unol â gofynion canllawiau arfarnu trafnidiaeth Cymru, a adnabyddir fel WelTAG. Mae seibiant yn yr astudiaethau ar hyn o bryd tra bod y patrymau traffig a'r galw ansefydlog yn dychwelyd i'r amodau cyfartalog ar ôl agor siop Trago Mills, y gwyddom ei fod wedi cynyddu galw yn sylweddol. Disgwylir i'r cyfnod ymsefydlu bara tua chwe mis, ac ar yr adeg honno bydd yr astudiaeth yn ailddechrau trwy brofi tueddiadau a ragwelir gyda'r rhai sy'n hysbys ar ôl agor Trago Mills. Bydd y profion sensitifrwydd yn hysbysu'n well priodoldeb yr atebion tymor hwy a gynigir. Ar ôl i'r astudiaethau cyfnod 2 ar hyd y coridor gael eu cwblhau a'u harfarnu, bydd ymyraethau trafnidiaeth i fynd i'r afael â thagfeydd yn cael sylw. Disgwylir i hynny gael ei gwblhau erbyn dechrau 2019, a cheir mesurau tymor canolig i fwrw ymlaen â nhw yn y cyfamser. Mater i awdurdodau cynllunio lleol ei ystyried yw'r mater ynghylch y terfynau amser ar gyfer caniatâd cynllunio yn ymwneud â datblygiadau mawr. Gwn fod gan Ysgrifennydd y Cabinet ymgynghoriad ar waith ar hyn o bryd, ac rwy'n siŵr y bydd yr awdurdod lleol a chithau yn ymateb i hwnnw. Yn yr achos hwn, fel y gwyddoch, gwnaed y penderfyniad ynghylch caniatâd cynllunio ym 1994 gan awdurdod cynllunio Morgannwg Ganol ac roedd yn cynnwys gwelliannau i'r briffordd a oedd yn briodol i raddfa'r datblygiad ar y pryd, ond, fel y mae'r Aelod wedi ei amlygu, mae'r sefyllfa honno wedi newid i raddau helaeth iawn. Felly, bydd yr astudiaethau yn llywio gwelliannau i'r ffordd ar ôl i'r traffig ymsefydlu unwaith eto.
