Aecom Technology Corporation (ATC) has developed a dehumidification system to prevent corrosion on the Humber Bridge in East Yorkshire, UK.

Aecom designed the dehumidification system and monitored the installation and commissioning process, following a $9.6m contract award from the Humber Bridge Board.

The dehumidification system will remove moisture from the suspension bridge’s main cables, maintain structural capacity, prolong the life-span of the bridge and prevent any further corrosion of the cables.

The cable-wrapping process was carried out from four separate gantries designed and manufactured by the contractor, C. Spencer, while Cableguard, an elastomeric membrane, supplied by the DS Brown Company, was also installed.
