Will the Cabinet Minister confirm whether the GG 119 Road Safety Audit for the A5 Menai suspension bridge approaches was accompanied by an engineering assessment of the potential structural and vibration impacts of the speed cushions on the bridge and masonry approach spans, and if so, will it be published?
A GG 119 - Road Safety Audit (RSA) was carried out which recommended that speed cushions be installed within the legally established 20 mph zone. It also concluded that that the prohibition on road cushions within 25 meters of a bridge does not apply under Regulation 7. The placement of the speed cushions is on the masonry approaches and not the Main Span of the Bridge, which removed the need to complete an engineering assessment. The RSA has not been published as there is no requirement for Welsh Government or UK Highways A55 Ltd. to publish them.
These measures have successfully reduced the average speeds on the bridge in line with the 20mph speed limit. This contributes to safer operations on the bridge and fewer closures.
