Yn rhan o'r gwaith hwn, gwnaed cais penodol mewn perthynas â chynllun gwella Cyffyrdd 14/15 a 16/16A ar yr A55. Gofynnwyd i'r Panel Adolygu Ffyrdd fynegi barn ynghylch a ddylai’r prosiect hwnnw gael blaenoriaeth ai peidio. Argymhellodd y Panel, yn hytrach na bwrw ymlaen â’r cynllun ar ei ffurf bresennol, fod achos cryf dros ystyried coridor cyfan Gogledd Cymru, fel yr argymhellwyd yn adroddiad terfynol Adolygiad Cysylltedd yr Undeb. Rwy’n cytuno â'r achos hwnnw ac, ar y sail honno, byddaf yn sefydlu Comisiwn Trafnidiaeth Gogledd Cymru, dan arweiniad yr Arglwydd Burns, a fydd yn gyfrifol am fynd ati ar sail tystiolaeth i ddatblygu argymhellion ar atebion integredig aml-ddull ym maes trafnidiaeth.
As part of the work, a specific request was made in relation to the A55 Junction 14/15 and 16/16A improvements scheme.  The Roads Review Panel was asked to provide its view on this project as a priority. The Panel recommended that instead of progressing in its current form, that there is a strong case for considering the whole North Wales corridor, as recommended in the Union Connectivity Review final report. I agree with this case and on this basis, I will be establishing a North Wales Transport Commission, led by Lord Burns, which will be responsible for taking an evidence-led approach to develop recommendations for multi-modal, integrated transport solutions.
