Bu Llywodraeth Cymru ac UK Highways A55 Ltd, ar y cyd â chwmnïau peirianneg Spencer Group a COWI, yn cydweithio i gyd-ddatblygu'r rhaglen frys. Roedd angen strategaeth ddylunio a chaffael bwrpasol ar gyfer y gwaith brys, a gafodd ei ddatblygu’n gyflym ar ôl i Bont Menai gael ei chau’n annisgwyl ar 21 Hydref 2022 oherwydd problem strwythurol a oedd yn peri risg i ddiogelwch y cyhoedd.
The Welsh Government and UK Highways A55 Ltd, alongside engineering firms Spencer Group and COWI, worked together to codevelop the emergency programme. The emergency works required a bespoke design and procurement strategy, which was developed at pace following the unexpected closure of the Menai Suspension Bridge on 21 October 2022 due to a structural issue that posed a risk to public safety.
