UK - Transportation - Bridges - Serious corrosion fears keep A4 Hammersmith flyover closed: London Bridge nursery rhyme instigates our mind

Transport for London has been forced to keep the vital A4 Hammersmith flyover closed for further inspections because of serious corrosion of steel supporting cables.

Problems with external concrete sprawling have been known about for several years, but engineers and maintenance contractor Amey have called for extra time to assess the extent of damage within the 900m bridge structure. The flyover was closed on 23 December due to concerns about a serious structural defect.

The damage to the ageing 1960′s structure has been caused by water ingress, including salt water due to grit laid during the winter months, which has corroded and weakened supporting cables.
