This Interim Advice Note (IAN) implements an Interim Management Strategy for reinforced concrete and steel/concrete composite half-joint deck detailing in suspended span and propped-cantilever bridges.

The risk based strategy is necessary to ensure that all structures of this type, which are particularly vulnerable to deterioration and difficult to inspect, are recorded, specially inspected, and remedial works planned, and to allow the future maintenance funding requirements to be identified.
