DMRB updates – new documents published – December 2019

The Design Manual for Roads and Bridges is being transformed into a consistent and concise format that is clear and easy to use, with content that is up to date and more efficient to maintain, and arranged using the data structure and connectivity that is needed to realise Highways England’s digital roads vision.

This significant improvement to the usability, structure and content of the DMRB is happening now, at an unprecedented rate. The 15,000 pages of the DMRB and the associated Interim Advice Notes are being updated and improved in time for the March 2020 deadline, and as we approach the final stage of this project, the rate of publication of the new documents is ramping up considerably. The message for all users of the DMRB is to be vigilant and check for the latest versions; at the end of every month there are many new documents being published, and many documents being withdrawn.
