Highway Design Manual
What's New
Would you like to be notified automatically of any changes or updates to the Highway Design Manual? If "YES" Click Here.
The latest English Version of the Highway Design Manual (HDM) is available on-line below in two formats.
The first format available is a .pdf file of the complete manual which will allow you to perform word searches of the complete manual and/or allow you to download or print the complete HDM cover to cover all at one time. This file is very large and may take some time to download.
A second format that is available below, in both Metric and English Versions, is the traditional chapter by chapter format. This format is easier to download and/or print. However, the traditional versions only allow for chapter by chapter word searches.
No matter which of the formats is used to download and/or print, if the HDM Holder chooses to do so, the Holder is responsible for keeping their electronic and/or paper copy up to date and current. For this reason, HDM Holders are encouraged to use the on-line versions of the HDM because they are the most current.
If you want to purchase a HDM binder, the chapter/section tabs, the original loose leaf pages, and loose leaf copies of all the manual change transmittals and errata memoranda to date, these are available through the Caltrans Publication Unit . If this option is chosen, the HDM Holder and not the Publications Unit is responsible for obtaining and inserting all of the change-sheets that are available on the Department Design website.
Design Information Bulletins (DIB's) and Design Memos may supercede this Manual
