First sections of new DMRB released

Highways England has published the first sections of its revised Design Manual for Roads and Bridges. The four sections cover: introductory text; requirements for safety risk assessment; use of compressive membrane action in bridge decks; and management of corrugated steel buried structures. The DMRB was first published in 1992 and now comprises more than 350 documents and associated interim advice notes. The updating process began last April and is due for completion by March 2020. HE’s chief highway engineer Mike Wilson thanked the devolved administrations and HE’s supply chain for supporting the review. Several UK consultants are working with HE on the update.
