The challenge

To carry out major full width repairs and resurfacing operations on both east and westbound carriageways whilst maintaining a through route for mainline traffic with access and egress to and from all frontages, businesses and affected stakeholders within the site, surrounding areas and diversion routes. In the mist of the Covid 19 pandemic.

Our solution

The Covid 19 pandemic proved to be an unexpected ally due to travel restrictions imposed which reduced traffic counts by over 50%. This enabled us to impose single lane running 24/7 without producing any delays. With the assistance of the Welsh Government and Flintshire County Council suitable diversion routes were identified which allowed us to completely close either the east or westbound carriageway overnight and from Friday at 7pm to Monday at 6am over the weekends.

Gatemen complete with body cameras were allocated to each entry point when the A55 was closed. Additional mitigation signs were erected explaining to the traveling public the essential work we were carrying out and that we were conforming to social distancing requirements.


Results and benefits

The works were completed on time within budget with minimum distribution.
