Er mwyn sicrhau cyn lleied â phosibl o oedi ac aflonyddwch wrth i dwnelau Brynglas gael eu hatgyweirio dros y ddwy flynedd nesaf rwyf wedi gofyn i’m swyddogion ystyried dulliau blaengar o ymdrin â’r traffig yn ystod y cyfnod hwn. Roedd hyn yn cynnwys ystyried technolegau twnel newydd a allai olygu nad oes angen cau’r twnelau. Nid yw’n amlwg eto a fyddai’r technolegau hyn, o safbwynt twnelau Brynglas, yn economaidd ac o’r herwydd bydd angen cyflwyno mesurau eraill er mwyn sicrhau cyn lleied â phosibl o effaith ar deithwyr.
To minimise the delays and disruption when the Brynglas tunnels are refurbished over the next two years, I asked my officials to consider innovative ways of dealing with the traffic during the repair works.  This included exploring new tunnel technologies that may have the ability to remove the need for tunnel closures.  Early indicators are that these technologies, in the instance of the Brynglas tunnels, will prove uneconomic and therefore other measures to minimise the effect on the travelling public will be required.
