The road safety audit was independently created for and held by UK Highways (A55) Ltd. It is not the Welsh Government’s document to publish. The design, location and implementation of the temporary speed cushions were developed in accordance with the audit's findings and any recommendations.

To assess the effectiveness of the measures, average vehicle speeds were monitored both before and after the installation of the speed cushions. The post-installation assessment demonstrated that average vehicle speeds had reduced to 20 mph, bringing driver behaviour in line with the posted speed limit. This reduction in vehicle speeds has enhanced safety for both bridge users and the workforce undertaking the Phase 2 works, supporting safer operations and reducing the risk of incidents in the work area.
