O dan yr amgylchiadau presennol, gweithredu gwrthlif dros dro ar yr A55 yw’r unig opsiwn penodol i sicrhau bod cerbydau nwyddau trwm nad ydynt yn barod yn gallu cael eu parcio mewn ffordd sy’n ddiogel o ran COVID-19 ac y gall traffig lleol barhau i lifo o amgylch Caergybi o 1 Ionawr.
In current circumstances, operating a temporary contraflow on the A55 is the only certain option to ensure unready HGVs can be parked in a Covid-secure way and local traffic can continue to flow around Holyhead from 1 January.
