The belt bridge and the foot­bridge had to be tem­pora­ri­ly sup­por­ted for the refur­bish­ment and/or exchan­ge of the bridge supports.
Modu­lar scaf­fol­ding ele­ments were uti­li­sed to trans­fer the loads from the brid­ges into the scaffolding.
Lif­ting loads were over­co­me by using bal­las­ting. Hori­zon­tal she­ar loads were trans­fer­red into the con­struc­tion site ground by uti­li­sing pegs.
