In May 2013 the 2010 Guide to Road Design Part 5: Drainage Design was substantially expanded and republished in three parts as:
- Part 5: Drainage – General and Hydrology Considerations
- Part 5A: Drainage – Road Surface, Networks, Basins and Subsurface
- Part 5B: Drainage – Open Channels, Culverts and Floodways
The three drainage Guides can be purchased individually or as a Drainage Set in hardcopy or PDF.
