    Brief

    National Highways is looking for suppliers to provide research services on Diverging Diamond Interchanges (DDIs). The initial phase (Stage 1) aims to assess the safety performance of DDIs compared to traditional junctions, identify potential risks such as Wrong Way Driving, review international standards for relevance to the UK, and analyze the current Design Manual for Roads and Bridges (DMRB) to determine necessary updates for DDIs. If further funding is secured, a second phase (Stage 2) will explore retrofitting DDIs at existing junctions, investigate risk mitigation strategies, measure environmental and economic benefits, and provide recommendations for updating the DMRB standards. The total value of this contract is approximately £94,496.76, and the deadline for submissions is June 18, 2025.
