 Mae Llywodraeth Cymru wedi buddsoddi £42 miliwn er mwyn gwella diogelwch yn y twnneli a’u gwneud yn fwy cydnerth ac fel rhan o’r buddsoddiad hwnnw, bu Dawnus yn gwneud gwaith i wella’r goleuadau rhwng cyffyrdd 16 ac 17\. Roedd Ysgrifennydd y Cabinet yn awyddus i bwysleisio bod rhagor o welliannau i’r A55 yn flaenoriaeth i’r adran.

 Dywedodd Ken Skates:

 
> “Mae’r gwaith adnewyddu ar y ffyrdd dynesu at y twnneli yn rhan o’n hymrwymiad i sicrhau bod pob un o’r tri thwnnel ar yr A55 yn cyrraedd y safonau sydd ohoni’r dyddiad hyn. Ers 2014, pan gafodd y twnneli eu gwella er mwyn cydymffurfio â chyfarwyddyd yr UE ar dwnneli, rydym wedi buddsoddi mewn systemau awyru newydd, systemau mecanyddol a thrydanol modern ac wedi gwella’r rhwystrau diogelwch. Mae gwaith wedi’i wneud hefyd i osod wyneb newydd ar y ffordd ac i wella arwyddion a seilwaith y twnnel, a bu’r canlyniadau’n rhai arbennig o dda.

>  “Ond nid dyna ddiwedd y gwaith o bell ffordd. Bydd proses debyg o gydgysylltu gwaith yn cael ei chynnal ar gyfer cam nesaf y gwaith rhwng Abergwyngregyn a Thai’r Meibion a Chyffyrdd 15 ac 16\. Hefyd, mae rhagor o welliannau ar y gweill eisoes neu yn yr arfaeth ar gyfer trydedd bont dros y Fenai a gwelliannau i Goridor Glannau Dyfrdwy. 
> 
>  “Dw i wedi dweud droeon bod angen i’r A55 wasanaethu cymunedau a busnesau ar draws y Gogledd a dw i’n hynod falch bod y gwelliannau wedi’u cwblhau ac y llwyddwyd i darfu cyn lleied â phosibl ar y cymunedau a’r busnesau hynny wrth i’r gwaith fynd rhagddo. Byddwn yn mynd ati bellach i fwrw ymlaen â rhagor o welliannau, gan wneud y gwaith dros nos eto os bydd modd, gan anelu at gwblhau’r gwaith ar bob un o’r tri thwnnel yn 2017”.

Lighting improvements between junctions 16 and 17 were carried out by Dawnus as part of Welsh Government’s £42 million investment in the safety and resilience of the tunnels and the Cabinet Secretary was keen emphasise that further A55 improvements were a priority for the department.

 Ken Skates said:

 
> “The refurbishment works to the tunnel approaches form part of our commitment to bringing all three A55 tunnels up to current day standards. Since 2014, when the tunnels were improved to be brought inline with the EU tunnel directive, we’ve invested in new ventilation, LED lighting, up to date mechanical and electrical systems and safety barrier improvements. In addition to this, resurfacing works, improved signing and works to the tunnel infrastructure have all taken place with first class results.
> 
>  “But the work must not and does not stop there. A similar coordination process will be undertaken for the next phase of works between Abergwyngregyn and Tai ‘r Meibion and Junction 15 and 16, with further improvements to a third crossing over the Menai Strait and the Deeside corridor also under way or in the pipeline. 
> 
>  “I’ve been very vocal about the need for the A55 to deliver for communities and businesses across North Wales and am delighted that these improvements have been completed with minimum disruption. We will now press ahead with further improvements, again overnight wherever possible, with a view to completing work on all three tunnels in 2017”
