Interim Advice Notes (IANs)
Interim Advice Notes (IANs) are “Design Manual for Roads and Bridges” (DMRB) Advice Notes. They are published pending the final advice notes.
What are IANs used for?
IANs are used by organisations involved in the improvement and operation of our road network. The IANs here should only be used in connection with works on motorways and trunk roads in Wales.
IANs must be read in conjunction with the Design Manual for Roads and Bridges (DMRB) and Manual of Contract Documents for Highway Works (MCHW) which are available on the Standards for highways website. (External link)
Status in Wales
The status of IANs in Wales can be found by selecting 'Interim Advice Notes Status in Wales' on the left hand side of this page.
Published Wales only
The Welsh Government publishes 'Wales Only' IANs. These are issued with the same reference number and suffixed with "(W)".
These can be found by selecting 'Published Wales Only Interim Advice Notes' on the left hand side of this page.
For the Highways Agency IANs used in England visit the Standards for highways website (External link).
