Interim Advice Notes (IANs)

IANs are issued by Highways England from time to time. They contain specific guidance, which shall only be used in connection with works on motorways and trunk roads in England, subject to any specific implementation instructions contained within an IAN.

While IANs must be read together with the DMRB and MCHW for the above works, and may incorporate amendments or additions to documents in these publications, they are not part of the DMRB or MCHW.
