Bydd angen cau ffyrdd dros dro ar gyfer cyflawni rhai agweddau ar y gwaith. Ymgynghorir â thrigolion a busnesau lleol ar gynlluniau, a bydd rhybudd ymlaen llaw am unrhyw waith. Bydd lonydd presennol yn cael eu cadw ar agor ar adegau prysur i’r graddau y bydd hynny’n bosibl, a bydd lonydd yn cael eu cau yn ystod oriau allfrig.
Temporary road closures will be required for certain aspects of the work. Local residents and businesses will be consulted on plans, with advance notice provided of any works. Existing lanes will be maintained at peak times as much as possible, with lane closures implemented during off peak hours.
